Abstract: Single-atom catalysis is the “hot spot” in the field of catalysis due to the special geometries, electronic states, and their unique catalytic performance. Single-atom catalysts(SACs), isolated metal atoms dispersed on the support, show the highest atom efficiency, cutting down the potential cost in the industrial process. Consequently, this “homo-hetero” catalyst could be a promising candidate for the next-generation catalysts. The applications for the SACs are widely reported, like gas-solid reactions, organic reactions, and electro-catalysis. In this mini- review, we will focus on the recent work of SACs on electro-catalysis, including hydrogen evolution reaction(HER), oxygen reduction reaction(ORR), oxygen evolution reaction(OER), CO2 reduction reaction(CO2 RR), and nitrogen reduction reaction(NRR).

Key words: Sing-atom catalyst, Hydrogen evolution reaction, Oxygen reduction reaction, Oxygen evolution reaction, CO2 reduction reaction, Nitrogen reduction reaction
