Electrochemical water splitting has received significant attention recently for the production of green hydrogen as a means to alleviate our need on fossil fuels. There has been immense progress on developing new catalysts that are active for the hydrogen evolution reaction (HER), the oxygen evolution reaction (OER) as well as materials that are bifunctional and are active for both reactions. In this perspective I detail recent developments in tailoring highly active interfacial regions in a variety of catalysts that are suitable for these reactions. In particular the doping of metal oxides and metal-chalcogenides with a secondary metal is discussed and how this influences the activity and stability of the catalyst and how in fact simple systems such as Ni/NiO are also highly active due to the presence of a metal/metal oxide interface. Finally the future direction in characterising electrocatalysts is discussed and the important role that spatially resolved electrochemical data ...

创建主动界面作为改善电化学水分解反应的策略

最近，电化学水分解技术已被广泛用于生产绿色氢，以减轻我们对化石燃料的需求。在开发对氢气析出反应（HER），氧气析出反应（OER）具有活性的新型催化剂以及双功能且对两个反应均具有活性的材料方面，已经取得了巨大进展。从这个角度讲，我详细介绍了在适合这些反应的各种催化剂中定制高活性界面区域的最新进展。尤其讨论了用二次金属掺杂金属氧化物和金属硫属元素化物，以及这如何影响催化剂的活性和稳定性，以及由于金属的存在，实际上简单的系统（如Ni / NiO）也具有很高的活性/金属氧化物界面。
