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

近年来，作为H2/O2进化的低成本催化剂，过渡金属二甲藻（TMD，EG MOS2，WS2）一直是激烈研究的主题。催化活性位点的化学反应目前越来越了解，该项目旨在通过以下方面的进步以：（i）通过形成多孔结构的受控TMD电沉积最大化边缘位点，（ii）通过金属掺杂，，通过金属掺杂，，修改催化位点（iii）优化活跃位点的稳定性。可交换： - 通过不同的方法对分层TM化合物的范围进行绘制，其物理表征随后是电化学表征，作为其/ORR和其他相关反应的催化剂，以及机械详细信息的定量评估
