| 1 | Nickel cobalt phosphide with three-dimensional nanostructure as al highly efficient electrocatalyst for hydrogen evolution reaction in both I acidic and alkaline electrolytes显示文摘Transition metal phosphides (TMPs) are promising candidates for noble metal free electrocatalysts in water splitting applicati ons. In this work, we prese nt the facile syn thesis of nickel cobalt phosphide electrocatalyst with three-dime nsional nano structure (3D-NiCoP) on the nickel foam, via hydrothermal reaction and phosphorization. The as-prepared electrocatalyst exhibits an excellent activity for hydrogen evolution reaction (HER) in both acidic and alkaline electrolytes, with small overpotentials to drive 10 mA/cm^2 (80 mV for 0.5 M H2SO4, 105 mV for 1 M KOH), small Tafel slopes (37 mV/dec for 0.5 M H2SO4, 79 mV/dec for 1 M KOH), and satisfying durability in long-term electrolysis. 3D-NiCoP also shows a superior HER activity compared to single metal phosphide, such as cobalt phosphide and nickel phosphide. The outstanding performa nee for HER suggests the great pote ntial of 3D-NiCoP as a highly efficient electrocatalyst for water splitting technology. | Bo Ma Zhengchun Yang Yantao Chen Zhihao Yuan | 2019 | Nano Research2019，12，2： | 14 |
| 2 | Ni-_2P-MoS_2/γ-Al_2O_3 Catalyst for Deep Hydrodesulfurization via the Hydrogenation Reaction Pathway显示文摘A series of highly active Ni2P-Mo S2/γ-Al2O3 catalysts were prepared and characterized, the catalytic performance of which was evaluated through hydrodesulfurization of dibenzothiophene. The result indicated that when the amount of Ni2 P was 4%, the catalyst showed a relatively high activity to provide a reliable reference for the hydrodesulfurization pathway in comparison with the conventional Ni Mo and Ni Mo P catalysts. The physicochemical properties of the catalysts were correlated with their catalytic activity and selectivity on hydrodesulfurization. The stacking number of active Mo S2 phases was important for influencing the hydrogenation activity. | Liu Lihua Liu Shuqun | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，4： | 13 |
| 3 | Roles of Lewis and Brnsted acid sites in NO reduction with ammonia on CeO_2-ZrO_2-NiO-SO_4^(2-) catalyst显示文摘Nickel and sulfate co-modified CeO2-ZrO2 catalysts were prepared by sol-gel method. The catalysts were characterized by XRD, FTIR, XPS, NH3 chemisorption and NH3-SCR activity tests. The results showed that the enhanced acidity of CeO2-ZrO2 catalysts by nickel and sulfate co-modification was responsible for the broadened temperature window and improved the selectivity to N2 in NH3-SCR deNOx. The introduction of nickel to CeO2-ZrO2 solid solutions resulted in more Ce3+ on surface of catalyst, leading to an increased Lewis acidity of catalyst. Higher Lewis acidity of catalyst facilitated ammonia activation at low temperature (<300 oC) and thereby improved the NH3-SCR activity. The enhanced high-temperature (>300 oC) activity and selectivity of catalysts arose from the introduction of Brnsted acid sites (less oxidative than Lewis acid sites) by sulfate modification. | 司知蠢 翁端 吴晓东 江洋 | 2010 | Journal of Rare Earths2010，28，5： | 12 |
| 4 | A Phenol-containing α-Diimine Ligand for Nickel-and Palladium-Catalyzed Ethylene Polymerization显示文摘A phenol-containing dibenzhydryl-based α-diimine ligand bearing hydroxy group on para-position of aniline moiety was designed, synthesized, and investigated in Ni-and Pd-catalyzed ethylene polymerization. The Ni complex bearing hydroxy groups resulted in not only high polyethylene molecular weight(Mn up to 1.5 × 10^~6), but also significantly increased melting temperature(Tm up to 123℃) and greatly decreased branching density(33/1000 C) versus the Ni catalyst bearing OMe group on para-position of aniline moiety. This is consistent with the hypothesis that the deprotonation of the phenol moiety generated a phenoxide bearing strong electrondonating O-substituent by methylaluminoxane(MAO) cocatalyst. The Pd complexes bearing hydroxy groups exhibited similar catalytic properties to those of the Pd catalyst bearing OMe groups did. | Chen Tan Wen-Min Pang Chang-Le Chen | 2019 | Chinese Journal of Polymer Science2019，37，10： | 11 |
| 5 | Electrochemical studies of nickel deposition from aqueous solution in super-gravity field显示文摘The effect of super-gravity on electrochemical deposition of nickel from aqueous solution was studied. The SEM pictures show that the microstructure of nickel film deposited under the super-gravity condition is finer and more uniform compared with that obtained in normal gravity condition, and the crystal grains diminish with the increase of super-gravity coefficient. The XRD patterns indicate that the ar-rangement of crystalline grains of nickel film deposited under the super-gravity field is more regular, and the crystalline grain sizes decrease with the increase of super-gravity coefficient. Toughness, tensile stress and hardness of the nickel film are markedly raised with the increase of super-gravity coefficient, and hydrogen content in the nickel film decreases with the increase of super-gravity coefficient. From the polarization curves of hydrogen evolution reaction under the su-per-gravity condition, a significant reduction of over-potential on electrode was found when current density increased. The process of hydrogen evolution reaction was enhanced under the super-gravity condition. The electro-deposition rate, the microstructure and properties of deposited nickel film under super-gravity condi-tion were still affected by the relative orientation between inertia force and depos-iting surface. It is favorable to gain the nickel film with better mechanic properties when inertia force orientates vertically towards depositing surface. | GUO ZhanCheng1,2, GONG YingPeng2 & LU WeiChang2 1 Metallurgical & Ecological School, University of Science and Technology, Beijing 100083, China 2 Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100080, China | 2007 | Science China(Technological Sciences)2007，50，1： | 10 |
| 6 | Enhancing hydrogen sorption in MgH_(2) by controlling particle size and contact of Ni catalysts显示文摘A comparative study based on MgH2 ball-milled with altered Ni particle sizes under different conditions was conducted to reveal the effect of close contact between hydrides and metal catalysts on their hydrogen sorption properties.It is found that the Mg+nano-Ni(5 at%)composites not only exhibit a substantial decreased onset desorption temperature by approximately 180℃ but also dramatically enhance the absorption kinetics by sixteen times in comparison with those of pure MgH_(2).This remarkable kinetics enhancement can be explained by the superior catalytic effect of Ni present in composites that highly depends on its particle size and its close contact with MgH2. | Ting-Zhi Si Xue-Yang Zhang Jing-Jing Feng Xiao-Li Ding Yong-Tao Li | 2021 | Rare Metals2021，40，4： | 8 |
| 7 | Facilitating Lithium-Ion Diffusion in Layered Cathode Materials by Introducing Li^(+)/Ni^(2+) Antisite Defects for High-Rate Li-Ion Batteries显示文摘Li^(+)/Ni^(2+) antisite defects mainly resulting from their similar ionic radii in the layered nickel-rich cathode materials belong to one of cation disordering scenarios.They are commonly considered harmful to the electrochemical properties,so a minimum degree of cation disordering is usually desired.However,this study indicates that LiNi_(0.8)Co_(0.15)Al_(0.05)O_(2)as the key material for Tesla batteries possesses the highest rate capability when there is a minor degree(2.3%)of Li^(+)/Ni^(2+) antisite defects existing in its layered structure.By combining a theoretical calculation,the improvement mechanism is attributed to two effects to decrease the activation barrier for lithium migration:(1)the anchoring of a low fraction of high-valence Ni^(2+) ions in the Li slab pushes uphill the nearest Li^(+)ions and(2)the same fraction of low-valence Li^(+) ions in the Ni slab weakens the repulsive interaction to the Li^(+) ions at the saddle point. | Zhongfeng Tang Sen Wang Jiaying Liao Shuo Wang Xiaodong He Bicai Pan Haiyan He Chunhua Chen | 2019 | Research2019，，1： | 8 |
| 8 | Closed-loop hydrometallurgical treatment of end-of-life lithium ion batteries: Towards zero-waste process and metal recycling in advanced batteries显示文摘This work presents an enhanced hydrometallurgical process for recycling lithium ion batteries. First, endof-life batteries were processed in a physical pre-treatment plant to obtain a representative electrode material. The resulting leachate was purified forth by iron-precipitation, liquid–liquid extractions, and an innovative Li–Na separation, in order to obtain valuable products. These products include high-grade graphite, cobalt oxide(Co3O4, purity 83%), cobalt oxalate(CoC2O4, purity 96%), nickel oxide(Ni O, purity89%), and lithium carbonate(Li2CO3, purity 99.8%). The recovery rate was quantitative for graphite, between 80% and 85% for cobalt depending on the nature of the recovery method, 90% for nickel, and 72%for lithium. Secondary streams were also valorized to obtain sodium sulfate(Na2SO4, purity 96%), and MnCoFe2O4 magnetic nano-sorbents according to the zero-waste concept. In order to close the loop, recycled Co3O4 and NiO were used as conversion-type anode materials for advanced lithium ion batteries showing promising performances. | Thomas Abo Atia Giuseppe Elia Robert Hahn Pietro Altimari Francesca Pagnanelli | 2019 | Journal of Energy Chemistry2019，28，8： | 8 |
| 9 | Effect of Ni on the corrosion resistance of bridge steel in a simulated hot and humid coastal-industrial atmosphere显示文摘The corrosion resistance of weathering bridge steels containing conventional contents of Ni(0.20 wt%, 0.42 wt%, 1.50 wt%) and a higher content of Ni(3.55 wt%) in a simulated hot and humid coastal-industrial atmosphere was investigated by corrosion depth loss, scanning electron microscopy–energy-dispersive X-ray spectroscopy, Raman spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and electrochemical methods. The results showed that, with increasing Ni content, the mechanical properties of the bridge steel were markedly improved, the welding parameters were satisfactory at room temperature, and the corrosion resistance was enhanced. When the Ni content was low(≤0.42 wt%), the crystallization process of the corrosion products was substantially promoted, enhancing the stability of the rust layer. When the Ni content was higher(~3.55 wt%), the corrosion reaction of the steel quickly reached a balance, because the initial rapid corrosion induced the formation of a protective rust layer in the early stage. Simultaneously, NiO and NiFe_2O_4 were generated in large quantities; they not only formed a stable, compact, and continuous oxide protective layer, but also strongly inhibited the transformation process of the corrosion products. This inhibition reduced the structural changes in the rust layer, thereby enhancing the protection. However, when the Ni content ranged from 0.42 wt% to 1.50 wt%, the corrosion resistance of the bridge steel increased only slightly. | Dong-liang Li Gui-qin Fu Miao-yong Zhu Qing Li Cheng-xiang Yin | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，3： | 7 |
| 10 | Surface engineering at the interface of core/shell nanoparticles promotes hydrogen peroxide generation显示文摘Hydrogen peroxide(H_2O_2), an environmentally friendly oxidant, has already been widely used in many chemical synthesis and industrials as an alternative to replace traditional oxidants including chlorinated oxidizers and strong acids. However, the conventional synthesis method confronts intense energy cost,tedious separation procedures and high cost, which is not competitive with traditional oxidants. Although direct H_2O_2 synthesis from H_2 and O_2 is a green and atomically economic reaction, satisfactory activity and desirable selectivity still remain formidable challenges. Herein, for the first time, a class of Pd@NiO-x nanoparticles(NPs)(x = 1, 2, 3 and 4) with a unique core@shell interface structure has been created to achieve high activity, selectivity and stability for the direct H_2O_2 synthesis. A precise thermal annealing on Pd@Ni-x NPs revealed that the resulting Pd@Ni O-x NPs exhibited the volcano-like activity toward direct H_2O_2 synthesis as a function of annealing temperature and time. By tuning the composition of Pd@Ni O-x NPs and the reaction condition, the efficiency of H_2O-2 synthesis could be well optimized with 5 wt%Pd@NiO-3/TiO_2 exhibiting the highest productivity(89 mol/(kg_(cat) h)) and selectivity(91%) to H_2O_2 as well as excellent stability, making it one of the best catalysts for direct H_2O_2 synthesis reported to date. | Yonggang Feng Qi Shao Bolong Huang Junbo Zhang Xiaoqing Huang | 2018 | National Science Review2018，5，6： | 7 |
| 11 | Extraction of metals from complex sulfide nickel concentrates by low-temperature chlorination roasting and water leaching显示文摘The recovery of valuable metals from complex sulfide concentrates was investigated via chlorination roasting followed by water leaching. A reaction process is proposed on the basis of previous studies and the results of our preliminary experiments. During the process,various process parameters were studied,including the roasting temperature,the addition of NH_4 Cl,the roasting time,the leaching time,and the liquid-to-solid ratio. The roasted products and leach residues were characterized by X-ray diffraction and vibrational spectroscopy. Under the optimum condition,95% of Ni,98% of Cu,and 88% of Co were recovered. In addition,the removal of iron was studied in the water leaching stage. The results demonstrate that this process provides an effective approach for extracting multiple metals from complex concentrates or ores. | Cong Xu Hong-wei Cheng Guang-shi Li Chang-yuan Lu Xiong-gang Lu Xing-li Zou Qian Xu | 2017 | International Journal of Minerals,Metallurgy and Materials2017，24，4： | 7 |
| 12 | The microscopic mechanical performance for nonuniform welded joint of nickel-based alloy with nanoindentation显示文摘To quantify the nonuniform micromechanical performance of welded joint,the load-displacement curves by nanoindentation test were introduced to examine different zones including base metal,coarse grained heat affected zone,partially melted zone,weld metal near the fusion boundary and weld metal center.The results showed that the strengthening effect of weld metal was more obvious than that of heat affected zone for nickel based welded joint and especially in coarse grained heat affected zone,the hardening resulted from overheating was not apparent.Nickel based weld metal with high content of alloying elements which were often segregated at interdendritic regions or precipitated in grain interior under nonequilibrium solidification contributed to the characteristics that differ from conventional low alloy steel welded joint. | 李晓泉 郝本行 陈一鑫 云叶菱 杨宗辉 | 2019 | China Welding2019，28，2： | 6 |
| 13 | A nanostructured Ni/T-Nb_(2)O_(5)@carbon nanofibers as a long-life anode material for lithium-ion batteries显示文摘In this work,nickel/T-Nb_(2)O_(5)nanoparticles encapsulated in mesoporous carbon nanofibers(denoted as Ni/T-Nb_(2)O_(5)@CNFs)are successfully prepared through a simple electrospinning route and succedent heating treatment.The presence of Ni in carbon nanofibers is beneficial for enhancing the electronic conductivity and the initial Coulombic efficiency.Ni/T-Nb_(2)O_(5)nanoparticles are homogeneously incorporated in carbon nanofibers to form a nanocomposite system,which provides effective buffering during the lithiation/delithiation process for cycling stability.The Ni/TNb_(2)O_(5)@CNFs show high surface area(26.321 m^(2)·g^(-1))and mesoporous microstructure,resulting in higher capacity and excellent rate performance.The Ni/T-Nb_(2)O_(5)@CNFs exhibit a remarkable capacity of 437 mAh·g^(-1)at a current density of0.5 A·g^(-1)after 230 cycles and a capacity of 173 mAh·g^(-1)at a current density up to 10.0 A·g^(-1)after 1400 cycles.This work indicates that nickel/T-Nb_(2)O_(5)nanoparticles encapsulated in carbon nanofibers can be a promising candidate for anode material in high-power LIBs. | Si-Ru He Jian-Peng Zou Li-Bao Chen Yue-Jiao Chen | 2021 | Rare Metals2021，40，2： | 6 |
| 14 | TiO_2担载镍催化剂上硝基苯液相加氢(英文)显示文摘The catalytic hydrogenation of nitrobenzene to aniline employing nickel impregnated on rutile,anatase,and high surface area titania supports has been investigated.The nickel is present in elemental state as fcc phase on the catalyst as evidenced by X-ray diffraction results.The Ni crystallite size was found to be greater for Ni/anatase.The temperature-programmed reduction results suggest a greater metal-support interaction for Ni/rutile.The observed order of catalytic activity for the hydrogenation of nitrobenzene is Ni/rutile > Ni/anatase > Ni/TiO2.A conversion of 99% was observed for Ni/rutile at 140 oC and hydrogen pressure of 1.96 MPa.Interestingly,aniline is the only product formed which demonstrates the catalytic hydrogenation of nitrobenzene proceeds with atom economy.Both Ni/rutile and Ni/anatase exhibited a better stability than Ni/TiO2.The hydrogenation proceeds with the preferential adsorption of hydrogen on nickel present in the catalyst surface,possibly assisted by TiOx species. | K.Joseph Antony RAJ M.G.PRAKASH R.MAHALAKSHMY T.ELANGOVAN B.VISWANATHAN | 2012 | 催化学报2012，33，8： | 6 |
| 15 | 镍钼杂多酸制备NiMo/γ-Al_2O_3催化剂及硼、钴或镍改性氧化铝的影响(英文)显示文摘A hydrotreating NiMo/γ-Al2O3 catalyst(12 wt% Mo and 1.1 wt% Ni) was prepared by impregnation of the support with the Anderson-type heteropolyoxomolybdate(NH4)4Ni(OH)6Mo6O18.Before impregnation of the support,it was modified with an aqueous solution of H3BO3,Co(NO3)2,or Ni(NO3)2.The catalysts were investigated using N2 adsorption,O2 chemisorption,X-ray diffraction,UV-Vis spectroscopy,Fourier transform infrared spectroscopy,temperature-programmed reduction,temperature-programmed desorption,and X-ray photoelectron spectroscopy.The addition of Co,Ni,or B influenced the Al2O3 phase composition and gave increased catalytic activity for 1-benzothiophene hydrodesulfurization(HDS).X-ray photoelectron spectroscopy confirmed that the prior loading of Ni,Co or B increased the degree of sulfidation of the NiMo/γ-Al2O3 catalysts.The highest HDS activity was observed with the NiMo/γ-Al2O3 catalyst with prior loaded Ni. | Radostina PALCHEVA Luděk KALUZA Alla SPOJAKINA Květue JIRTOV Georgi TYULIEV | 2012 | 催化学报2012，33，6： | 6 |
| 16 | 镍催化剂用于超高分子量聚乙烯的制备显示文摘Ziegler and Natta won the Nobel Prize in 1963 due to their contributions in olefin polymerization catalysis.Subsequent studies into related catalysts have led to a multibillion-dollar polyolefin industry.Currently,more than 178 million tons of polyolefin materials are produced annually,which constitute more than half of global plastics production.Interestingly,the metal nickel was initially recognized as a“poison”for olefin polymerization.Alkyl aluminum species can oligomerize ethylene(degree of polymerization up to 100)at high temperature and pressure;while the addition of nickel salt to the system led to the exclusive formation of 1-butene.This famous“nickel effect”marks the starting point of the era of Ziegler catalysts[1].After decades of research,the situation of nickel has changed dramatically,and a large number of nickelbased catalysts have been shown with the capabilities of producing high-molecular-weight polyethylene.As an exceptional demonstration,some groups have recently developed nickel catalysts that are able to produce ultra-high molecular weight polyethylene(UHMWPE).UHMWPE,with molecular weight of above one-million,is a special class of advanced engineering plastics with superior properties and wide applications. | 谭忱 陈昶乐 | 2020 | Science Bulletin2020，65，14： | 6 |
| 17 | In-situ growth of vertically aligned nickel cobalt sulfide nanowires on carbon nanotube fibers for high capacitance all-solid-state asymmetric fiber-supercapacitors显示文摘Fiber-supercapacitors(FSCs)are promising power sources for miniature portable and wearable electronic devices.However,the development and practical application of these FSCs have been severely hindered by their low volumetric capacitance and narrow operating voltage.In this work,vertically aligned nickel cobalt sulfide(Ni Co2S4)nanowires grown on carbon nanotube(CNT)fibers were achieved through an in-situ two-step hydrothermal reaction method.The as-prepared Ni Co2S4@CNT fiber electrode exhibits a high volumetric capacitance of 2332 F cm-3,benefiting from its superior electric conductivity,large surface area,and rich Faradic redox reaction sites.Furthermore,a Ni Co2S4@CNT//VN@CNT(vanadium nitride nanosheets grown on CNT fibers)asymmetric fiber-supercapacitor(AFSC)was successfully fabricated.The device exhibits an operating voltage up to 1.6 V and a high volumetric energy density of 30.64m Wh cm-3.The device also possesses outstanding flexibility as evidenced by no obvious performance degradation under various bending angles and maintaining high capacitance after 5000 bending cycles.This work promotes the practical application of flexible wearable energy-storage devices. | Na Liu Zhenghui Pan Xiaoyu Ding Jie Yang Guoguang Xu Linge Li Qi Wang Meinan Liu Yuegang Zhang | 2020 | Journal of Energy Chemistry2020，29，2： | 5 |
| 18 | Effect of Partial Substitution of Ni by Cu in LaNiO_3 Perovskite Catalyst for Dry Methane Reforming显示文摘A series of ternary perovskite type oxides LaNi1-xCuxO3(x = 0.2,0.4,0.6,0.8,and 1.0) were synthesized via the sol-gel method in propionic acid.Partial substitution of Ni by Cu showed higher activities and selectivities towards syngas products.LaNi0.8Cu0.2O3 was the most active toward the CH4 and CO2 conversions,and was selective for syngas products.Temperature-programmed reduction results showed that the addition of Cu facilitates the reduction of Ni3+ to Ni0,which is the main reason for the higher performance of this catalyst. | G.R.MORADI F.KHOSRAVIAN M.RAHMANZADEH | 2012 | 催化学报2012，33，5： | 5 |
| 19 | Partial hydrogenation of adiponitrile to 6-aminocapronitrile over Ni/α-Al_2O_3 catalyst promoted with K_2O and La_2O_3显示文摘A novel K2O and La2O3 promoted nickel catalyst supported on a-Al2O3 was prepared by co-impregnation method, and it exhibited higher activity and 6-aminocapronitrile selectivity than Ni/a-Al2O3 during the hydrogenation of adiponitrile in the absence of ammonia, i.e., K2O and La2O3 improved the performance of the nickel-based catalyst. | Lei Zhao, Cai Yun Wang, Ji Xiang Chen , Ji Yan Zhang Department of Catalysis Science and Engineering, School of Chemical Engineering and Technology, Tianjin University, Tianjin 300072, China | 2007 | Chinese Chemical Letters2007，18，6： | 5 |
| 20 | Highly efficient and selective photocatalytic dehydrogenation of benzyl alcohol for simultaneous hydrogen and benzaldehyde production over Ni-decorated Zn_(0.5)Cd_(0.5)S solid solution显示文摘Photocatalytic conversion of solar energy into hydrogen and high value-added fine chemicals has attracted increasing attention. Herein, we demonstrate an efficient photocatalytic system for simultaneous hydrogen evolution and benzaldehyde production by dehydrogenation of benzyl alcohol over Nidecorated Zn_(0.5)Cd_(0.5)S solid solution under visible light. The photocatalytic system shows an excellent hydrogen production rate of 666.3 μmol h^(-1) with high stability. The optimal apparent quantum yield of52.5% is obtained at 420 nm. This noble-metal-free photocatalytic system displays much higher activity than pure Zn_(0.5)Cd_(0.5)S and Pt-loaded Zn_(0.5)Cd_(0.5)S solid solution. Further studies reveal that the metallic Ni nanocrystals play an important role in accelerating the separation of photogenerated charge carriers and the subsequent cleavage of α-C–H bond during dehydrogenation of benzyl alcohol. | Lei Zhang Daochuan Jiang Rana Muhammad Irfan Shan Tang Xin Chen Pingwu Du | 2019 | Journal of Energy Chemistry2019，28，3： | 5 |
