Research indicates that single-atom catalysts (SACs) show great potential in promoting the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), but there are still some issues to be addressed, such as alloy-based SACs, carbon-based SACs, and SACs supported on other compounds. Therefore, the future direction should focus on further optimizing the activity and stability of SACs.
Electrochemical water splitting is regarded as the most promising approach to produce hydrogen. However, the sluggish electrochemical reactions occurring at the anode and cathode, namely, the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER), respectively, consume a tremendous amount of energy, seriously hampering its wide application. Recently, single-atom catalysts (SACs) have been proposed to effectively enhance the kinetics of these two reactions. In this minireview, we focus on the recent progress in SACs for OER and HER applications. Three classes of SACs have been reviewed, i.e., alloy-based SACs, carbon-based SACs and SACs supported on other compounds. Different factors affecting the activities of SACs are also highlighted, including the inherent element property, the coordination environment, the geometric structure and the loading amount of metal atoms. Finally, we summarize the current problems and directions for future development in SACs. (C) 2021, Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Published by Elsevier B.V.
