摘要

The idea of single-atom catalysts (SACs) has gained attention in electrocatalysis owing to its high efficien-cies in energy conversion reactions. Supported single-atoms (SAs) exhibit major advantages, such as high atom utilization, strong interfacial interaction, and well-defined active centers, compared with nanopar-ticles. From a practical point of view, SACs comprising non-noble metals seem to be an attractive alter-native to expensive noble-metal catalytic systems. As the intrinsic activity and the electronic structure of SACs are governed by the support material and coordination environment of the metal species. Two-dimensional (2D) materials could be a promising candidates for supporting SAs owing to their high chem-ical stabilities and layered structures. This review provides an overview of recent developments in 2D materials-supported non-noble metal SACs for electrochemical energy conversion applications. The rel-evance of performing the comprehensive characterization of the 2D supported catalysts to elucidate their catalytic activities under different reaction conditions were highlighted. In light of recent findings in the field, we discussed the existing challenges and future opportunities regarding the correlation between the 2D structures and activities of SACs toward electrochemical energy conversion reactions.(c) 2022 Elsevier B.V.
