多相电催化在能源供应和各种化学品生产的可持续、碳中和途径的发展中起着核心作用。它决定了涉及电极/电解质界面催化的电化学装置的总体效率。从这个角度来看，我们讨论了识别电催化剂表面活性中心的关键方面和影响它们的重要因素。在这项工作中，表面结构、纳米颗粒形状/大小和电解质组成在催化性能中的作用是特别感兴趣的。我们强调了从我们的角度来看需要解决的挑战，并为可再生能源供应系统的“现实生活”电催化剂的设计以及工业上重要化合物的生产提供指导。
Heterogeneous electrocatalysis plays a central role in the development of sustainable, carbon-neutral pathways for energy provision and the production of various chemicals. It determines the overall efficiency of electrochemical devices that involve catalysis at the electrode/electrolyte interface. In this perspective, we discuss key aspects for the identification of active centers at the surface of electrocatalysts and important factors that influence them. The role of the surface structure, nanoparticle shape/size and the electrolyte composition in the resulting catalytic performance is of particular interest in this work. We highlight challenges that from our point of view need to be tackled, and provide guidelines for the design of "real life" electrocatalysts for renewable energy provision systems as well as for the production of industrially important compounds.
