Modified transition metal catalysts for hydrogen and oxygen evolution

过渡金属二卤化物(TMD，如MoS_2、WS_2)作为一种低成本的析氢催化剂，近年来已成为研究热点。目前，人们对催化活性中心的化学有了更多的了解，该项目试图通过以下方式在这些最新进展的基础上：(I)通过可控的TMD电沉积形成多孔结构来最大化边缘中心，(Ii)通过金属掺杂来修饰催化中心，(Iii)优化活性中心的稳定性。交付成果：-通过不同的方法制造一系列层状TM化合物，先进行物理表征，然后进行电化学表征，作为HER/ORR和其他相关反应的催化剂，以及对机理细节进行定量评估

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
