| 1 | A comparison between acute large vessel occlusion in the posterior circulation and anterior circulation after endovascular treatment:the ANGEL-ACT registry experience显示文摘Background and purpose Endovascular treatment(EVT)has shown an overwhelming benefit for acute anterior circulation artery occlusion(ACO).Whether it can achieve the same outcomes in posterior circulation artery occlusion(PCO)has not been well explained.We aimed to evaluate the characteristics and prognosis of ACO and PCO after EVT in a nationwide registry.Method The present analysis was based on the prospective ANGEL-ACT Registry in China between November 2017 and March 2019.Demographic data,periprocedural times,recanalisation rate,intracranial haemorrhage(ICH)and 90-day functional outcomes were compared between the ACO and PCO groups.Results A total of 1793 patients were analysed including 397(22.1%)consecutive patients with PCO and 1396(77.9%)patients with ACO treated with EVT.A larger proportion of patients with PCO had intracranial atherosclerotic disease and received extra angioplasty during EVT.Successful recanalisation and 90-day favourable functional outcomes did not differ significantly between the two groups.Patients with PCO showed lower 24-hour ICH and symptomatic ICH rates.There was a trend towards higher mortality rate in the PCO group(22.09%vs 14.44%;adjusted OR 1.286(95%CI 0.820 to 2.017),p=0.2731),especially when the onset to puncture time was over 6 hours(30.77%vs 11.13%;adjusted OR 2.673(95%CI 1.280 to 5.583),p=0.0089,interactive p=0.0002).Conclusions In this large prospective multicentre registry,there was a significant difference in the characteristics and periprocedural features between patients with PCO and ACO.However,successful recanalisation and 90-day favourable functional outcomes in PCO were equivalent to those in ACO. | Xuan Sun Jingyu Zhang Xu Tong Baixue Jia Dapeng Mo Ning Ma Feng Gao Lian Liu Xiaochuan Huo Ligang Song Yiming Deng Zhongrong Miao | 2022 | Stroke & Vascular Neurology2022，7，4： | 4 |
| 2 | Unstable Ni leaching in MOF-derived PtNi-C catalyst with improved performance for alcohols fuel electro-oxidation显示文摘Significance of unstable species leaching was for the first time demonstrated on MOF-derived catalysts by taking PtNi-C as an example,that was instructive for the relevant catalyst fabrication and performance study.PtNi-C catalyst was synthesized by combining Pt nanoparticles with Ni-BTC after annealing in the tube furnace and the unstable Ni species can be easily leached out in nitric acid,and the stable PtNi nanoparticles trapped in the graphite carbon layer were obtained.The greatly improved catalytic ability for alcohol fuels oxidation was verified by comparing the fresh and acid leached catalysts in terms of the high peak current density,specific and mass activity and rapid charge transfer kinetics and high catalytic stability.The current work guides the importance of unstable assistant promoter removal for the MOF derived catalysts. | Bo Fang Zong Liu Yufei Bao Ligang Feng | 2020 | Chinese Chemical Letters2020，31，9： | 3 |
| 3 | Staged angioplasty versus regular carotid artery stenting in patients with carotid artery stenosis at high risk of hyperperfusion:a randomised clinical trial显示文摘Background and purpose Hyperperfusion(HP)is a devastating complication associated with carotid artery stenting(CAS)or endarterectomy.The efficacy and safety of staged angioplasty(SAP)in patients with CAS at high risk of HP remains unclear.We sought to determine whether SAP is superior to regular CAS in patients with high risk of HP.Methods A randomised,multicentre open-label clinical trial with blinded outcome assessment(STEP)was conducted.Patients with severe carotid stenosis at high risk of HP were randomly assigned(1:1)to the SAP or regular CAS group.The primary endpoint was hyperperfusion syndrome(HPS)and intracerebral haemorrhage(ICH)within 30 days after the procedure.Results From November 2014 to January 2017,a total of 64 patients were enrolled in 11 centres.33 patients were allocated to the SAP group and 31 to the regular CAS group.At 30 days,the rate of primary endpoint was 0.0%(0/33)in the SAP group and 9.7%(3/31)in the regular CAS group(absolute risk reduction(ARR),9.7%;95%CI−20.1% to 0.7%;p=0.11).As one of the secondary endpoints,the incidence of HP phenomenon(HPP)was lower in the SAP group than the regular CAS group(0.0%vs 22.6%,ARR,−22.6%;95% CI−36.8%to−10.2%;p=0.04).Conclusion The rate of HPS and ICH was not significantly lower in SAP group;the extended secondary endpoint of HPP,however,significantly reduced,which suggested that SAP may be a safe and effective carotid revascularisation procedure to prevent HP. | Dapeng Mo Baixue Jia Huaizhang Shi Yaxuan Sun Qingan Liu Chengzhe Fan Jianping Deng Jinglin Yuan Wei Wu Changchun Jiang Guilian Zhang Hanjun Du Ning Ma Feng Gao Xuan Sun Ligang Song Lian Liu Guangge Peng Yongjun Wang Yilong Wang Zhongrong Miao the STEP Study Group | 2021 | Stroke & Vascular Neurology2021，6，1： | 3 |

| 5 | PdNi/N-doped graphene aerogel with over wide potential activity for formic acid electrooxidation显示文摘Anti-CO poisoning ability is significant in formic acid oxidation in the fuel cell technique.Herein,Pd Ni alloy supported on N-doped graphene aerogel(Pd Ni/GA-N)was found to have catalytic ability toward formic acid electrooxidation over a wide potential range because of the improved anti-CO poisoning ability.This catalyst was fabricated by simple freeze-drying of mixture solution of graphene aerogel,polyvinylpyrrolidone,Pd^(2+)and Ni^(2+)and the subsequent thermal annealing reduction approach in the N2/H2 atmosphere.Pd-Ni alloy particles anchored over the folding N-doped graphene surface with a porous hierarchical architecture structure in the 3 D directions.It showed the catalytic performance of its maximum mass activity of 836 m A mg^(-1)in a broad potential range(0.2-0.6 V)for formic acid oxidation.The CO stripping experiment demonstrated its largely improved anti-CO poisoning ability with the peak potential of 0.67 V,approximately 60 and 40 m V less compared to those of Pd/GA-N and Pd/C samples.The high anti-CO poisoning ability and strong electronic effect resulting from the interaction between the3 D GA-N support and the Pd-Ni alloy makes it a promising catalyst for application in direct formic acid fuel cells. | Yufei Bao Meng Zha Pengliang Sun Guangzhi Hu Ligang Feng | 2021 | Journal of Energy Chemistry2021，30，8： | 3 |
| 6 | NiSe_(2)-CoSe_(2) with a Hybrid Nanorods and Nanoparticles Structure for Efficient Oxygen Evolution Reaction显示文摘Hetero-structure induced high performance catalyst for oxygen evolution reaction(OER)in the water splitting reaction has received increased attention.Herein,we demonstrated a novel catalyst system of NiSe_(2)-CoSe_(2) consisting of nanorods and nanoparticles for the efficient OER in the alkaline electrolyte.This catalyst system can be easily fabricated via a low-temperature selenization of the solvothermal synthesized NiCo(OH)x precursor and the unique morphology of hybrid nanorods and nanoparticles was found by the electron microscopy analysis.The high valence state of the metal species was indicated by X-ray photoelectron spectroscopy study and a strong electronic effect was found in the NiSe_(2)-CoSe_(2) catalyst system compared to their counterparts.As a result,NiSe_(2)-CoSe_(2) exhibited high catalytic performance with a low overpotential of 250 mV to reach 10 mA·cm^(-2) for OER in the alkaline solution.Furthermore,high catalytic stability and catalytic kinetics were also observed.The superior performance can be attributed to the high valence states of Ni and Co and their strong synergetic coupling effect between the nanorods and nanoparticles,which could accelerate the charge transfer and offer abundant electrocatalytic active sites.The current work offers an efficient hetero-structure catalyst system for OER,and the results are helpful for the catalysis understanding. | Meng Li Ligang Feng | 2022 | Chinese Journal of Structural Chemistry2022，41，1： | 3 |
| 7 | Plasmonic tip internally excited via an azimuthal vector beam for surface enhanced Raman spectroscopy显示文摘The synergy of a plasmonic tip and fiber-based structure light field excitation can provide a powerful tool for Raman examination. Here, we present a method of Raman spectrum enhancement with an Ag-nanoparticles(Ag-NPs)-coated fiber probe internally excited via an azimuthal vector beam(AVB), which is directly generated in a few-mode fiber by using an acoustically induced fiber grating. Theoretical analysis shows that gap mode can be effectively generated on the surface of the Ag-NPs-coated fiber probe excited via an AVB. The experimental result shows that the intensity of Raman signal obtained with analyte molecules of malachite green by exciting the Ag-NPs-coated fiber probe via an AVB is approximately eight times as strong as that via the linear polarization beam(LPB), and the activity of the AVB-excited fiber probe can reach 10^-11 mol∕L, which cannot be achieved by LPB excitation.Moreover, the time stability and reliability are also examined, respectively. | Min Liu Wending Zhang Fan fan Lu Tianyang Xue Xin Li Lu Zhang Dong Mao Ligang Huang Feng Gao Ting Mei Jianlin Zhao | 2019 | Photonics Research2019，7，5： | 3 |
| 8 | Hetero MOF-on-MOF-derived carbon nanotube interconnected nitrogen-doped carbon-encapsulated FeNi/FeF2 for efficient oxygen evolution reaction显示文摘Heterostructures derived from metal–organic frameworks(MOFs)with multicomponent synergism are significant in the energy conversion and catalysis reactions.Herein,we demonstrated such an efficient catalyst with the structure of self-catalyzed nitrogen-doped carbon nanotube interconnected FeNi/FeF2 derived from hetero-zeolite imidazolate frameworks 8(ZIF-8)on Fe2Ni MIL(MIL represents Materials of Institut Lavoisier)for oxygen evolution reaction.The obtained catalyst showed efficient synergism of the multicomponents,high polarity,more active sites exposure,increased intrinsic activity,and improved conductivity and stability by a carbon interconnected and confined structure as revealed by the spectroscopic analysis and electrochemical measurements.It required an overpotential of only ca.240mV(no iR correction)to reach the current density of 10mAcm^(−2) in a KOH solution when loaded on an inert glass carbon electrode,much better than similar kinds of catalysts.The improved catalytic performance can be well correlated to the structural transformation step by step from different MOFs to their derivatives by subsequent carbonation and fluorination.Because of the above-mentioned structural advantages,good catalysis performance of high activity and stability,faster catalytic kinetics,and facile active phase formation were observed compared to those of other similar materials.This work offers a new platform of derivatives from hetero MOF-on-MOF for catalysis reactions. | Yang Zhou Hui Liu Xiaocong Gu Xiang Wu Ligang Feng | 2022 | Carbon Energy2022，4，5： | 2 |
| 9 | Graphene aerogel supported Pt-Ni alloy as efficient electrocatalysts for alcohol fuel oxidation显示文摘Alcohol fuels oxidation plays a significant role in carbon sustainable cycling and high-performance cata-lyst with a strong anti-poisoning effect is desired.Herein,Pt-Ni alloy supported on the N-doped graphene aerogel synthesized by simple freeze-drying and annealing was demonstrated to have such catalytic abil-ity for alcohol fuel oxidation.Pt-Ni alloy particles were found uniformly dispersed over the surface of 3D N-doped graphene aerogel.High anti-poisoning ability for CO-like intermediates oxidation was demon-strated by the CO-stripping experiment.The as-prepared catalyst was found to have outstanding catalytic performance for methanol and ethanol oxidation with high catalytic activity,stability and catalytic ki-netics.Compared to the control samples,the improved catalytic ability could be due to the presence of oxophilic Ni species and the support effect of 3D N-doped graphene aerogel that combined multi-advantages of large surface area,facile mass transfer,and abundant defects. | Xiang Ding Meng Li Junling Jin Xiaobing Huang Xiang Wu Ligang Feng | 2022 | Chinese Chemical Letters2022，33，5： | 2 |
| 10 | Electrochemical oxygen evolution reaction efficiently boosted by selective fluoridation of FeNi3 alloy/oxide hybrid显示文摘Performance boosting of hybrid metal oxide and metal alloy catalyst is crucial to the water electrolysis for hydrogen generation. Herein, a novel concept of selective fluoridation of metal alloy/oxide hybrid is proposed to boost their catalytic performance for the oxygen evolution reaction(OER). A well-recognized OER catalyst system of FeNi3 alloy/oxide embedded in nitrogen-doped porous nanofibers(FeNiO/NCF) is employed as a proof of concept, and it is selectively fluoridated by transforming the metal oxide to metal fluoride(FeNiF/NCF). The crystal structure and surface chemical state transformation are well supported by the spectroscopic analysis and the improved electrochemical performance for OER can be well correlated to the phase and structure change. Specifically, FeNiF/NCF can drive the benchmark current density of 10 mA cm-2 at 260 mV with a Tafel slope of 67 mV dec-1, about 70 mV less than that of FeNiO/NCF.Increased catalytic kinetics, rapid charge transfer ability, high catalytic efficiency and stability are also probed by electrochemical analysis. The high surface area and roughness are found mainly generated via the high-temperature annealing for the metal alloy/metal oxide formation, and the low-temperature fluoridation process intrinsically contributes to the active structure formation. It is an efficient and universal approach to increase the catalytic performance of metal alloy/oxide for energy-relevant catalytic reactions. | Meng Zha Chengang Pei Quan Wang Guangzhi Hu Ligang Feng | 2020 | Journal of Energy Chemistry2020，29，8： | 2 |
| 11 | Electrochemical deposited amorphous FeNi hydroxide electrode for oxygen evolution reaction显示文摘The electrodeposition approach is significant in electrode fabrication for practical application.Herein,the electrodeposited amorphous NiFe hydroxide species for oxygen evolution reaction (OER) in water splitting reaction is demonstrated by revealing the synergistic effect influenced by the support electrode of Fe and Ni foil and the contents of Fe and Ni in the electrolyte.All the electrodeposited samples have an amorphous structure and similar profiles of binding energy and chemical states for Fe and Ni as characterized by the spectroscopic techniques.While the support effect and Fe/Ni synergistic effect are indeed observed for the varied catalytic performances observed for the different electrodes;the Ni foil supported catalyst exhibits much higher performance than that of the Fe foil supported catalyst,and the different redox potentials of Ni species in the different Fe/Ni electrode resulting from the Fe–Ni synergism are observed in the cyclic voltammetry curve analysis.The surface roughness and the electrochemical surface area are also influenced by the support effect and the Fe/Ni ratio in the plating electrolyte.The optimal electrode shows a very low overpotential of~200 mV to reach 10 mA cm^(-2),and very high catalytic stability by the consecutive cyclic voltammetry measurements and 20 h stability test.Though it has the largest electrochemical surface area,the highest catalytic efficiency for these active sites is also indicated by the specific activity and turnover frequency polarization curves.The current work shows the effective experience for the electrodeposited Fe/Ni based catalysts in large-scale fabrication,which can be more practical for hydrogen generation in the alkaline water electrolysis. | Zhengzhi Yin Runze He Yongcai Zhang Ligang Feng Xiang Wu Thomas Wågberg Guangzhi Hu | 2022 | Journal of Energy Chemistry2022，31，6： | 2 |
| 12 | High valence state of Ni and Mo synergism in NiS_(2);MoS_(2)hetero-nanorods catalyst with layered surface structure for urea electrocatalysis显示文摘High valence state species are significant in the energy-relevant electrochemical oxidation reactions.Herein,the high active state of Ni^(3+)formation induced by Mo^(6+)and their efficient synergism in NiS_(2)-MoS_(2)hetero-nanorods powder catalyst with the rough layered structure are demonstrated,as proof of concept,for the urea-assisted water electrolysis.This catalyst can be derived from the sulfidation of NiMoO_(4) nanorods that can realize individual metal sulfides sufficiently mixing at a domain size in the nanoscale which creates lots of active sites and nanointerfaces.The high valence state of Mo^(6+)and Ni^(3+)formation and increased conductive phase of 1 T MoS_(2)in the hetero-nanorods compared to the counterpart pure phases are revealed by spectral study and microscopic analysis;high electrochemical surface area and active site exposure are found due to the nano-interface formation and layered rough nanosheets over the surface of nanorods.They show much higher catalytic performance than their pure phases for urea oxidation,including high catalytic activity,stability,charge transfer ability and catalytic kinetics resulting from more active Ni^(3+)species formation and electronic synergism of high valence metals.Transformation of 1 T MoS_(2)to Mo^(6+)and increased amount of Mo^(6+)and Ni^(3+)after stability test indicate their involvement and synergism for the catalysis reaction.The current work offers a novel understanding of the synergistic effect based on the high valence state synergism for heterogeneous catalysts in electrocatalysis. | Shuli Wang Linyu Zhao Jiaxin Li Xinlong Tian Xiang Wu Ligang Feng | 2022 | Journal of Energy Chemistry2022，31，3： | 1 |
| 13 | Interface engineering of plasmonic induced Fe/N/C-F catalyst with enhanced oxygen catalysis performance for fuel cells application显示文摘The low intrinsic activity of Fe/N/C oxygen catalysts restricts their commercial application in the fuel cells technique;herein,we demonstrated the interface engineering of plasmonic induced Fe/N/C-F catalyst with primarily enhanced oxygen reduction performance for fuel cells applications.The strong interaction between F and Fe-N4 active sites modifies the catalyst interfacial properties as revealed by X-ray absorption structure spectrum and density functional theory calculations,which changes the electronic structure of Fe-N active site resulting from more atoms around the active site participating in the reaction as well as super-hydrophobicity from C–F covalent bond.The hybrid contribution from active sites and carbon support is proposed to optimize the three-phase microenvironment efficiently in the catalysis electrode,thereby facilitating efficient oxygen reduction performance.High catalytic performance for oxygen reduction and fuel cells practical application catalyzed by Fe/N/C-F catalyst is thus verified,which offers a novel catalyst system for fuel cells technique. | Xue Yin Ligang Feng Wen Yang Yuanxi Zhang Haiyan Wu Le Yang Lei Zhou Lin Gan Shaorui Sun | 2022 | Nano Research2022，15，3： | 1 |

| 16 | Surface modulated hierarchical graphene film via sulfur and phosphorus dual-doping for high performance flexible supercapacitors显示文摘Graphene surface modification by heteroatom incorporation is an attractive strategy to construct flexible electrochemical capacitors.Herein,the steam-assistant heteroatoms of sulfur and phosphorus dualdoped graphene film(s-SPG)is fabricated via an ice-template and thermal-activation approach and they demonstrate an excellent pseudocapacitive behavior in flexible electrochemical capacitors.As probed by various microscopic and spectroscopic analysis,well-maintained porosity structure is formed during the freeze-drying and steam-activation treatment;the increased surface roughness is ascribed to heteroatoms doping by the formation of S-and P-containing functional groups as electrochemical active sites.A flexible device integrated by porous s-SPG film shows high pseudocapacitive behavior with high specific capacitance(169 F/g),rate capability(91.7%)and cyclic stability(92.5%).Even at the bend angle of 120,no obvious change of specific capacitance is found indicating a good flexibility of s-SPG devices;the current study shows that s-SPG is a very promising electrode to realize the practical applications of all solid flexible supercapacitors. | Xu Yu Chengang Pei Ligang Feng | 2019 | Chinese Chemical Letters2019，30，5： | 1 |
| 17 | Active sites contribution from nanostructured interface of palladium and cerium oxide with enhanced catalytic performance for alcohols oxidation in alkaline solution显示文摘Nanostructured interface is significant for the electrocatalysis process. Here we comparatively studied the electrooxidation of alcohols catalyzed by nanostructured palladium or palladium-cerium oxide. Two kinds of active sites were observed in palladium-cerium oxide system, attributing to the co-action of Pd-cerium oxide interface and Pd sites alone, by CO stripping technique, a structure-sensitive process generally employed to probe the active sites. Active sites resulting from the nanostructured interfacial contact of Pd and cerium oxide were confirmed by high resolution transmission electron microscopy and electrochemical CO stripping approaches. Electrochemical measurements of cyclic voltammetry and chronometry results demonstrated that Pd-cerium oxide catalysts exhibited much higher catalytic performances for alcohols oxidation than Pd alone in terms of activity, stability and anti-poisoning ability.The improved performance was probably attributed to the nanostructured active interface in which the catalytic ability from each component can be maximized through the synergistic action of bi-functional mechanism and electronic effect. The calculated catalytic efficiency of such active sites was many times higher than that of the Pd active sites alone. The present work showed the significance of valid nanostructured interface design and fabrication in the advanced catalysis system. | Fulong Wang Huaguang Yu Zhiqun Tian Huaiguo Xue Ligang Feng | 2018 | Journal of Energy Chemistry2018，27，2： | 1 |
| 18 | Explicating the Role of Metal Centers in Porphyrin-Based MOFs of PCN-222(M) for Electrochemical Reduction of CO_(2)显示文摘The porphyrin-based MOFs formed by combining Zrclusters and porphyrin carboxylic acids with clear M-Nactive centers show unique advantages in electrocatalytic reduction of CO(CORR). However, its conductivity is still the bottleneck that limits its catalytic activity due to the electrical insulation of the Zr cluster. Therefore, the porphyrin-based MOFs of PCN-222(M)(M = Mn, Co, Ni, Zn) with explicit M-Ncoordination were combined with the highly conductive material carbon nanotube(CNT) for discussing the influence of metal centers on the CORR performance based on theoretical calculations and experimental observations. The results show that the PCN-222(Mn)/CNT, PCN-222(Co)/CNT, and PCN-222(Zn)/CNT all exhibit high selectivity to CO(FECO > 80%) in the range of-0.60 to-0.70 V vs. RHE. The FECOmax of PCN-222(Mn)/CNT(-0.60 V vs. RHE), PCN-222(Co)/CNT(-0.65 V vs. RHE), and PCN-222(Zn)/CNT(-0.70 V vs.RHE) are 88.5%, 89.3% and 92.5%, respectively. The high catalytic activity of PCN-222(Mn)/CNT and PCN-222(Co)/CNT comes from the excellent electron mobility of their porphyrin rings and their low ΔG*COOH(0.87 and 0.58 eV). It reveals that the strength of backbonding π of the transition metal and its influence on the electron mobility in the porphyrin ring can affect its CORR activity. | Mengjie Liu Mengting Peng Baoxia Dong Yunlei Teng Ligang Feng Qiang Xu | 2022 | Chinese Journal of Structural Chemistry2022，41，7： | 1 |
