Regulations of active moiety in single atom catalysts for electrochemical hydrogen evolution reaction

Peng Zhu et al.

Summary: Hydrogen production from water splitting using renewable electric energy is a key topic for achieving a carbon neutral future. Single atom catalysts (SACs) have emerged as a new frontier in catalysis, particularly in the hydrogen evolution reaction (HER), due to their high activity and excellent chemical selectivity. However, the influence of the neighboring coordinated atoms from the supports is often neglected in the classification of SACs. This review proposes a new classification method based on the type of supports and highlights the importance of the metal-support interaction and coordination environment. Structural designing strategies are also proposed to address the current challenges in SACs for HER.
