| 1 | Ni/Al_2O_3 catalysts for CO methanation: Effect of Al_2O_3 supports calcined at different temperatures显示文摘The correlation between phase structures and surface acidity of Al2O3 supports calcined at different temperatures and the catalytic performance of Ni/Al2O3 catalysts in the production of synthetic natural gas(SNG) via CO methanation was systematically investigated. A series of 10 wt% NiO/Al2O3 catalysts were prepared by the conventional impregnation method, and the phase structures and surface acidity of Al2O3 supports were adjusted by calcining the commercial γ-Al2O3 at different temperatures(600–1200 C). CO methanation reaction was carried out in the temperature range of 300–600 C at different weight hourly space velocities(WHSV = 30000 and 120000 mL·g-1h-1) and pressures(0.1 and 3.0 MPa). It was found that high calcination temperature not only led to the growth in Ni particle size, but also weakened the interaction between Ni nanoparticles and Al2O3 supports due to the rapid decrease of the specific surface area and acidity of Al2O3 supports. Interestingly, Ni catalysts supported on Al2O3 calcined at 1200 C(Ni/Al2O3-1200) exhibited the best catalytic activity for CO methanation under different reaction conditions. Lifetime reaction tests also indicated that Ni/Al2O3-1200 was the most active and stable catalyst compared with the other three catalysts, whose supports were calcined at lower temperatures(600, 800 and 1000 C). These findings would therefore be helpful to develop Ni/Al2O3 methanation catalyst for SNG production. | Jiajian Gao Chunmiao Jia Jing Li Meiju Zhang Fangna Gu Guangwen Xu Ziyi Zhong Fabing Su | 2013 | Journal of Energy Chemistry2013，22，6： | 16 |
| 2 | Atomically thin defect-rich Ni-Se-S hybrid nanosheets as hydrogen evolution reaction electrocatalysts显示文摘Facile design of economic-effective hydrogen evolution reaction(HER)catalysts with non-noble materials are promising for the production of renewable chemical fuels.Two-dimensional(2D)ultrathin transition metal dichalcogenides(TMDs)materials with large specific surface area and abundant catalytic active sites can significantly enhance their catalytic activities.Herein,we design and synthesize an atomically thin Ni-Se-S based hybrid nanosheet(NiSe1.2S0.8)via a simple solvothermal method,the thickness of NiSe1.2S0.8 nanosheets is only about 1.1 nm.Benefiting from the ultrathin nanostructure and rich defects,the optimal NiSe1.2S0.8 exhibits good electrocatalytic activity with the overpotential of 144 mV at−10 mA·cm−2,a small Tafel slope of 59 mV·dec−1,and outstanding catalytic stability in acid electrolyte for HER.The theoretical results show that hybrid electrocatalyst by S incorporation possesses the optimal adsorption free energy of hydrogen(ΔGH*).This study provides a simple method to synthesize a highperformance multicomponent electrocatalysts with the ultrathin nanostructures and abundant defects. | Jianpeng Sun Xiangting Hu Zhaodi Huang Tianxiang Huang Xiaokang Wang Hailing Guo Fangna Dai Daofeng Sun | 2020 | Nano Research2020，13，8： | 5 |
| 3 | Coking-resistant Ni-ZrO_2/Al_2O_3 catalyst for CO methanation显示文摘Highly coke-resisting Zr O2-decorated Ni/Al2O3 catalysts for CO methanation were prepared by a two-step process. The support was first loaded with Ni O by impregnating method and then modified with Zr O2 by deposition-precipitation method(IM-DP). Nitrogen adsorptiondesorption, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, H2 temperatureprogrammed reduction and desorption, NH3temperature-programmed desorption, and zeta potential analysis were employed to characterize the samples. The results revealed that, compared with the catalysts with the same composition prepared by co-impregnation(CI) and sequential impregnation(SI) methods, the Ni/Al2O3 catalyst prepared by IM-DP showed much enhanced catalytic performance for syngas methanation under the condition of atmospheric pressure and a high weight hourly space velocity of 120000 m L g-1 h-1. In a 80 h life time test under the condition of 300–600°C and 3.0 MPa, this catalyst showed high stability and resistance to coking, and the amount of deposited carbon was only 0.4 wt%. On the contrary, the deposited carbon over the catalyst without Zr O2 reached 1.5 wt% after a 60 h life time test. The improved catalytic performance was attributed to the selective deposition of Zr O2 nanoparticles on the surface of Ni O rather than Al2O3, which could be well controlled via changing the electrostatic interaction in the DP procedure. This unique structure could enhance the dissociation of CO2 and generate surface oxygen intermediates, thus preventing carbon deposition on the Ni particles in syngas methanation. | Qing Liu Fangna Gu Jiajian Gao Huifang Li Guangwen Xu Fabing Su | 2014 | Journal of Energy Chemistry2014，23，6： | 4 |
| 4 | Facile preparation of N-doped corncob-derived carbon nanofiber efficiently encapsulating Fe2O3 nanocrystals towards high ORR electrocatalytic activity显示文摘Facile preparation of cost-effective and durable porous carbon-supported non-precious-metal/nitrogen electrocatalysts for oxygen reduction reaction(ORR)is extremely important for promoting the commercialized applications of such catalysts.In this work,the FeCl3-containing porphyrinato iron-based covalent porous polymer(FeCl3·FeP or-CPP)was fabricated in-situ onto porous corncob biomass supports via a simple one-pot method.Subsequent thermal-reduction pyrolysis at 700℃-900℃with CO2 gas as an activating agent resulted in Fe2O3-decorated and N-doped graphitic carbon composite Fe2O3@NC&bio-C with a high degree of graphitization of Fe-involved promotion during pyrolysis(Fe2O3=FeCl3·FePor-CPP derived Fe2O3;NC=N-doped graphene analog;bio-C=the corncob-derived hierarchically porous graphitic biomass carbon framework).The derivedα-Fe2O3 andγ-Fe2O3 nanocrystals(5-10 nm particle diameter)were all immobilized on the N-doped bio-C micro/nanofibers.Notably,the Fe2O3@NC&bio-C obtained at the pyrolysis temperature of 800℃(Fe2O3@NC&bio-C-800),exhibited unusual ORR catalytic efficiency via a 4-electron pathway with the onset and half-wave potentials of 0.96 V and 0.85 V vs.RHE,respectively.In addition,Fe2O3@NC&bio-C-800 also exhibited a high and stable limiting current density of-6.0 mA cm-2,remarkably stability(larger than 91%retention after 10000 s),and good methanol tolerance.The present work represents one of the best results for iron-based biomass material ORR catalysts reported to date.The high ORR activity is attributed to the uniformly distributedα-Fe2O3 andγ-Fe2O3 nanoparticles on the N-enriched carbon matrix with a large specific surface area of 772.6 m^2 g^-1.This facilitates favor faster electron movement and better adsorption of oxygen molecules on the surface of the catalyst.Nevertheless,comparative studies on the structure and ORR catalytic activity of Fe2O3@NC&bioC-800 with Fe2O3@bio-C-800 and NC&bio-C-800 clearly highlight the synergistic effect of the coexisting Fe2O3 nanocrystals,NC,and bio-C on the ORR performance. | Wei Yan Yanling Wu Yanli Chen Qi Liu Kang Wang Ning Cao Fangna Dai Xiyou Li Jianzhuang Jiang | 2020 | Journal of Energy Chemistry2020，29，5： | 3 |
| 5 | Ordered mesoporous Cu-Ca-Zr:A superior catalyst for direct synthesis of methyl formate from syngas显示文摘It is still a big challenge to obtain both highly active and stable Cu-based catalysts for direct synthesis of methyl formate(MF)from syngas.To address the issue,we have designed and synthesized a series of ternary Cu-Ca-Zr catalysts,namely,the ordered mesoporous Cu-Ca-Zr catalyst prepared by one-pot evaporation-induced self-assembly(EISA)method,and the supported CuO/CaO-ZrO_(2)catalysts by impregnating with copper precursor or by immobilizing copper nanoparticles.In the latter two catalysts,the ordered mesoporous CaO-ZrO_(2)support was also prepared by the EISA method.The catalysts were characterized by techniques such as ICP,XRD,TEM,N2 isotherm adsorption-desorption,XPS and H2-TPR,and used for direct synthesis of MF.The results indicated that the catalyst prepared by onepot EISA method,in which the CuO species are highly dispersed in frame of CaO-ZrO_(2),exhibits much better activity and stability as compared with the other two catalysts with most of CuO located on the outer surface of the CaO-ZrO_(2)support,because the former has a higher specific surface area,enhanced synergistic effect and stronger interaction between the CaO-ZrO_(2)support and CuO active constituent. | Jiahao Zhuang Bin Lu Fangna Gu Ziyi Zhong Fabing Su | 2018 | Carbon Resources Conversion2018，1，2： | 2 |

| 9 | A 3D Ba-MOF for selective adsorption of CO_(2)/CH_(4)and CO_(2)/N_(2)显示文摘An unexpected in-situ hydrolysis reaction occurred during the solvothermal reaction of N,N’-bis(4-carboxy-2-methylphenyl)pyromellitic di-imide)and Ba(NO3)2,and a novel porous Ba-MOF,[H_(2)N(CH_(3))_(2)]_(0.5)[Ba_(1.5)(L)(DMA)]·1.5 DMA·1.5 H_(2)O(UPC-70,H_(3)L=2-(4-ca rboxy-2-methylphenyl)-1,3-dioxoisoindoline-5,6-dicarboxylic acid,DMA=N,N-dimethylacetamide),was obtained on the basis of the partial hydrolysate.The as-synthesized 3 D network with 1 D open channels of different sizes(24 A and 10 A)contains abundant open metal sites after removal of solvents,which is conducive to the preferential adsorption of CO_(2).The subsequent gas sorption measurement reveals the high separation selectivity of UPC-70 for CO_(2)/CH_(4)(15)and CO_(2)/N_(2)(32)at ambient conditions,and GCMC theoretical simulation provides good verification of the experimental results,indicating that UPC-70 is a potential candidate for CO_(2)capture from flue gas and natural gas. | Xiaokang Wang Yutong Wang Kebin Lu Weifeng Jiang Fangna Dai | 2021 | Chinese Chemical Letters2021，32，3： | 1 |

| 11 | Synthesis, structure, and magnetism of three manganese-organic framework with PtS topology显示文摘Three 3D manganese-organic frameworks, Mn2(BPTC)(DMF)2(H2O)·DMF·3H2O(1), Mn2(BPTC)(bipy)(DMF)·DMF·H2O(2), and Mn2(BPTC)(phen)(DMF)·EtOH(3), have been solvothermally synthesized using 3,3′,5,5′-biphenyltetracarboxylic acid(H4BPTC). All complexes are characterized by PXRD, EA, IR and TG. The results show that they all bear the PtS topology with(42.84)(42.84) for the vertex symbols of the planar and tetrahedral nodes, in which the BPTC ligand is considered as a square-planar 4-connected linker, and every binuclear SBU connected to the four BPTC ligands is simplified into tetrahedral 4-connected nodes. Because the three coordination sites of one metal center of SBU are occupied by the coordinated solvent molecules, complex 1 exhibits low stability. After substituting 2,2′-bipy or 1,10-phen for two coordinated solvent molecules, complexes 2 and 3 display evidently higher structure stability. The magnetism property of complex 2 is also discussed in detail. | MENG QingGuo DAI FangNa ZHANG LiangLiang WANG RongMing SUN DaoFeng | 2014 | Science China Chemistry2014，57，11： | 1 |

| 20 | Two alkynyl functionalized Co(Ⅱ)-MOFs as fluorescent sensors exhibiting selectivity and sensitivity for Fe3+ and nitroaromatic compounds显示文摘Two Co(II)-MOFs with different structures were successfully synthesized under the premise of designing two ligands containing alkynyl functional groups. Complexes 1 ([Co(TEPA)(TPT)2/3]·2DMF·H2O) and 2 ([Co(EPA)(TPT)]·1.5DMF·1.5H2O) show excellent luminescence properties. Meanwhile, as fluorescent sensors, complexes 1 and 2 exhibit selectivity and sensitivity for Fe3+ with the Ksv of 1.520 ×104 L/mol and 3.543 ×104 L/mol, which can rapidly detect nitroaromatic compounds in methanol and ethanol, especially for 2,4-NPH through fluorescence quenching with high quenching efficiency. In particular, the Ksv value of complexes 1 and 2 towards 2,4-NPH can reach up to 1.627 ×105 L/mol and 9.600 ×104 L/mol, demonstrating that complexes 1 and 2 are good candidates for the identification and detection of Fe3+and nitroaromatic compounds. | Yue Li Xia Wang Chengyong Xing Xiurong Zhang Zelong Liang Xiaokang Wang Kai Zhang Yutong Wang Di Liu Weidong Fan Fangna Dai | 2019 | Chinese Chemical Letters2019，30，7： | 0 |
