| 1 | Photo-assisted electrochemical hydrogen evolution by plasmonic Ag nanoparticle/nanorod heterogeneity显示文摘Transition metal sulfide-based hydrogen evolution electrocatalysts still lag in catalytic activity due to the zero-deviated free energy of*H adsorption.Plasmonic metals bridge the gap between light utilization and plasmon-mediated redox reactions for substantially enhanced electrocatalytic activity.In this work,a strategic broadband light utilization heterostructure,composed of two distinct Ag nanostructures(discontinuous Ag nanorods and monodispersed nanoparticles),is achieved through in situ sulfurization and metal leaching.The heterostructure benefits the electrocatalytic hydrogen evolution reactivity thanks to the localized surface plasmon resonance induced hot electrons injection and inter-gap electric fields revealed by the finite-difference time-domain simulation.Experimentally,the prudent heterostructured catalyst exhibits a significantly improved overpotential(at 10 mA cm−2)from 151 to 95 mV along with a Tafel slope from 74 to 45 mV dec−1 toward hydrogen evolution.Significantly,this instructional study sheds light on the design of hybrid photo-assisted electrocatalysts with cooperative effect of solar energy toward sustainable electrocatalysis. | Hao Wu Husam N.Alshareef Ting Zhu | 2019 | InfoMat2019，1，3： | 3 |
| 2 | Tungsten Blue Oxide as a Reusable Electrocatalyst for Acidic Water Oxidation by Plasma-Induced Vacancy Engineering显示文摘In contrast to alkaline water electrolysis,acidic water electrolysis remains an elusive goal due to the lack of earth-abundant,efficient,and acid-stable water oxidation electrocatalysts.Here,we show that materials with intrinsically poor electrocatalytic activity can be turned into active electrocatalysts that drive the acidic oxygen evolution reaction(OER)effectively.This development is achieved through ultrafast plasma sputtering,which introduces abundant oxygen vacancies that reconstruct the surface electronic structures,and thus,regulated the surface interactions of electrocatalysts and the OER intermediates.Using tungsten oxide(WO_(3))as an example,we present a broad spectrum of theoretical and experimental characterizations that show an improved energetics of OER originating from surface oxygen vacancies and resulting in a significantly boosted OER performance,compared with pristine WO_(3).Our result suggests the efficacy of using defect chemistry to modify electronic properties and hence to improve the OER performance of known materials with poor activity,providing a new direction for the discovery of acid-stable OER catalysts. | Hanfeng Liang Zhen Cao Chuan Xia Fangwang Ming Wenli Zhang Abdul-Hamid Emwas Luigi Cavallo Husam N.Alshareef | 2021 | CCS Chemistry2021，3，3： | 1 |

| 4 | An aqueous 2.1 V pseudocapacitor with MXene and V-MnO_(2) electrodes显示文摘MXenes have shown record-breaking redox capacitance in aqueous electrolytes,but in a limited voltage window due to oxidation under anodic potential and hydrogen evolution under high cathodic potential.Coupling Ti3C2Tx Xene negative electrode with RuO_(2) or carbon-based positive electrodes expanded the voltage window in sulfuric acid electrolyte to about 1.5 V.Here,we present an asymmetric pseudocapacitor using abundant and eco-friendly vanadium doped MnO_(2) as the positive and Ti_(3)C_(2)Tx MXene as the negative electrode in a neutral 1M Li2SO4 electrolyte.This all-pseudocapacitive asymmetric device not only uses a safer electrolyte and is a much less expensive counter-electrode than RuO_(2),but also can operate within a 2.1 V voltage window,leading to a maximum energy density of 46 Wh/kg.This study also demonstrates the possibility of using MXene electrodes to expand the working voltage window of traditional redox-capable materials. | Jiabin Wu Qun Li Christopher E.Shuck Kathleen Maleski Husam N.Alshareef Jun Zhou Yury Gogotsi Liang Huang | 2022 | Nano Research2022，15，1： | 0 |
| 5 | Defect Engineering of Disordered Carbon Anodes with Ultra-High Heteroatom Doping Through a Supermolecule-Mediated Strategy for Potassium-Ion Hybrid Capacitors显示文摘Amorphous carbons are promising anodes for high-rate potassium-ion batteries.Most low-temperature annealed amorphous carbons display unsatisfactory capacities.Heteroatom-induced defect engineering of amorphous carbons could enhance their reversible capacities.Nevertheless,most lignocellulose biomasses lack heteroatoms,making it a challenge to design highly heteroatom-doped carbons(>10 at%).Herein,we report a new preparation strategy for amorphous carbon anodes.Nitrogen/sulfur co-doped lignin-derived porous carbons(NSLPC)with ultra-high nitrogen doping levels(21.6 at%of N and 0.8 at%of S)from renewable lignin biomacromolecule precursors were prepared through a supramolecule-mediated pyrolysis strategy.This supermolecule/lignin composite decomposes forming a covalently bonded graphitic carbon/amorphous carbon intermediate product,which induces the formation of high heteroatom doping in the obtained NSLPC.This unique pyrolysis chemistry and high heteroatom doping of NSLPC enable abundant defective active sites for the adsorption of K+and improved kinetics.The NSLPC anode delivered a high reversible capacity of 419 mAh g^(-1)and superior cycling stability(capacity retention of 96.6%at 1 A g^(-1)for 1000 cycles).Potassiumion hybrid capacitors assembled by NSLPC anode exhibited excellent cycling stability(91%capacity retention for 2000 cycles)and a high energy density of 71 Wh kg^(-1)at a power density of 92 W kg^(-1). | Lei Zhao Shirong Sun Jinxin Lin Lei Zhong Liheng Chen Jing Guo Jian Yin Husam N.Alshareef Xueqing Qiu Wenli Zhang | 2023 | Nano-Micro Letters2023，15，3： | 0 |
| 6 | Recent developments in three-dimensional Zn metal anodes for battery applications显示文摘Aqueous zinc(Zn)ion batteries(AZIBs)are regarded as one of the promising candidates for next-generation electrochemical energy storage systems due to their low cost,high safety,and environmental friendliness.However,the commercialization of AZIBs has been severely restricted by the growth of dendrite at the Zn metal anode.Tailoring the planar-structured Zn anodes into threedimensional(3D)structures has proven to be an effective way to modulate the plating/stripping behavior of Zn anodes,resulting in the suppression of dendrite formation.This review provides an up-to-date review of 3D structured Zn metal anodes,including working principles,design,current status,and future prospects.We aim to give the readers a comprehensive understanding of 3D-structured Zn anodes and their effective usage to enhance AZIB performance. | Jianyu Chen Yizhou Wang Zhengnan Tian Jin Zhao Yanwen Ma Husam N.Alshareef | 2024 | InfoMat2024，6，1： | 0 |
