| The development of new energy sources using electrocatalytic technologies is a new strategy that can replace conventional energy sources, thus further addressing the massive use of fossil fuels and the associated environmental problems. Thus searching for stable and efficient electrocatalyst is crucial for the diffusion of these technologies. Single-atom catalysts (SACs) with distributed atomic active sites on a vector are novel materials in the field of catalysis with promising applications and have now become a research niche in electrocatalysis. The current review describes the general carriers, preparation methods of single-atom electrocatalyst, and their advanced characterization methods in detail. The single-atom electrocatalysts for energy transformation and environmental protection (CO2 reduction, water splitting) applications are also comprehensively summarized systematically. We briefly describe the catalytic mechanism based on the recent progress of various single-atom catalyst studies. And finally, in discussing the challenges and prospects for developing single-atom catalysts in the direction of electrocatalysis, we expect to contribute to the synthesis, design and application of single-atom electrocatalysts to facilitate better development in electrocatalytic energy conversion. |
