▎ 摘　　要

Based on the ultrasonic cavitation assisted hydrogen implosion method, Pt nanoparticles (NPs)/nitrogen-doped graphene nanohybrid scrolls (Pt NPs/N-GNSs) were synthesized. As the results of the N-doping and high reduction degree of graphene, and scroll structure of the nanohybrids, the Pt NPs/N-GNSs electrocatalyst shows excellent performance in the direct oxidation of methanol: low onset and peak potentials, high oxidation current, and good long-term cycle stability. The Pt NPs/N-GNSs should have great promising applications in heterogeneous catalysis and fuel cells.
