1钴-镍双金属磷化物中空纳米笼用于高效电解水显示文摘制备一种低成本、高效、稳定耐用的双功能电催化剂对于电催化水分解至关重要.本文采用自模板策略和原位磷化工艺相结合的方法构建了一种具有中空结构的钴镍双金属磷化物纳米笼(CoNiP_(x)).由于其独特的中空结构和钴镍双金属之间的协同效应,合成的CoNiP_(x)中空纳米笼催化剂在全pH值范围的电解质中对析氢反应均表现出优异的电催化活性和稳定性,并在1.0 mol L^(-1)氢氧化钾(KOH)中对析氧反应也表现出很好的电化学性能.CoNiP_(x)中空纳米笼作为阳极和阴极的双功能催化剂也显示出了优异的全解水性能,在20 mA cm^(-2)电流密度下,电压值为1.61 V,且稳定性良好.王志远 杨佳 王文玉 周方耀 周煌 薛正刚 熊灿 余振强 吴宇恩 2021Science China Materials2021,64,4:5

4Shining Light on Anion-Mixed Nanocatalysts for Efficient Water Electrolysis: Fundamentals, Progress, and Perspectives显示文摘Hydrogen with high energy density and zero carbon emission is widely acknowledged as the most promising candidate toward world’s carbon neutrality and future sustainable eco-society.Water-splitting is a constructive technology for unpolluted and high-purity H2 production,and a series of non-precious electrocatalysts have been developed over the past decade.To further improve the catalytic activities,metal doping is always adopted to modulate the 3d-electronic configuration and electron-donating/accepting(e-DA)properties,while for anion doping,the electronegativity variations among different non-metal elements would also bring some potential in the modulations of e-DA and metal valence for tuning the performances.In this review,we summarize the recent developments of the many different anion-mixed transition metal compounds(e.g.,nitrides,halides,phosphides,chalcogenides,oxyhydroxides,and borides/borates)for efficient water electrolysis applications.First,we have introduced the general information of water-splitting and the description of anion-mixed electrocatalysts and highlighted their complementary functions of mixed anions.Furthermore,some latest advances of anion-mixed compounds are also categorized for hydrogen and oxygen evolution electrocatalysis.The rationales behind their enhanced electrochemical performances are discussed.Last but not least,the challenges and future perspectives are briefly proposed for the anion-mixed water dissociation catalysts.Yaoda Liu Paranthaman Vijayakumar Qianyi Liu Thangavel Sakthivel Fuyi Chen Zhengfei Dai 2022Nano-Micro Letters2022,14,3:1

6A mini-review of noble-metal-free electrocatalysts for overall water splitting in non-alkaline electrolytes显示文摘Development of noble-metal-free materials with remarkable electrocatalytic water-splitting performance in acidic or neutral media has sparked considerable attention in recent years.Herein,we review the latest research on design and fabrication of precious-metal-free catalytic materials for overall water electrolysis in non-alkaline environment,especially highlighting several optimizing approaches to enhance the catalytic behavior and to realize effective bifunctional electrocatalysts.All these involved noble-metal-free electrocatalysts are classified into transition-metal oxides(TMOs),transition-metal nitrides(TMNs),transition-metal carbides(TMCs),transition-metal phosphides(TMPs),transition-metal chalcogenides,metal complexes,and metal-free carbons,as shown in the main part.Besides,the paper also offers an introduction of the fundamental electrochemistry of water splitting before entering the subject,as well as a prospective discussion on mechanism understanding,novel catalysts fabrication,and standardized performance measurements/evaluation in the last section.Jie Yu Yawen Dai Qijiao He Dongqi Zhao Zongping Shao Meng Ni 2021Materials Reports(Energy)2021,1,2:0
