We performed a systematic study of CO oxidation on a single Pt atom supported on penta-graphene (Pt/PG) by utilizing spin-polarized first-principles calculations. The results manifested that Pt/PG, as a single-atom catalyst, exhibited excellent catalytic activity toward CO oxidation and provided a novel strategy for the design of single-atom catalysts based on penta-graphene.
