Transition metal dichalcogenides (TMDs, eg MoS2, WS2) have been the subject of intense research in recent years as low-cost catalysts for H2/O2 evolution. The chemistry of the catalytically active sites is currently becoming more understood, and this project seeks to build on these recent advances through:(i) maximising edge sites through controlled TMD electrodeposition forming porous structures, (ii) modifying the catalytic sites through metal doping, (iii) optimising the stability of active sites.Deliverables:-Fabrication of range of layered TM compounds via different methods, with physical characterisation followed by electrochemical characterisation as catalysts for HER/ORR and other relevant reactions, and quantitative evaluation of mechanistic details

过渡金属二硫属化物（TMDs，如MoS 2，WS 2）作为低成本的H2/O2析氢催化剂，近年来成为研究热点。催化活性位点的化学性质目前已被越来越多的人所了解，该项目旨在通过以下方式建立在这些最新进展的基础上：（i）通过可控TMD电沉积形成多孔结构来最大化边缘位点，（ii）通过金属掺杂来修饰催化位点，（iii）优化活性位点的稳定性。产品：-通过不同方法制造一系列层状TM化合物，通过物理表征，然后通过电化学表征作为HER/ORR和其他相关反应的催化剂，并定量评估机理细节
