Abstract Phosphorus is incorporated into graphene (PG) by thermal treating method, which is further employed as supports for Pt nanoparticles. The as-obtained Pt/PG catalyst exhibits over 2.4 times enhanced methanol electrooxidation activity compared with Pt/C, as well as desirable stability and remarkably improved CO-tolerance. These improvements are attributed to not only uniformly dispersed Pt nanoparticles that are anchored by introduced defects in PG, but also negative d-band center shift and weakened CO adsorption on Pt caused by strong interactions between Pt and PG. Consequently, PG is a promising support material for Pt-based catalysts towards methanol electrooxidation.
