| Abstract: | We have designed a new Pt/SnO2/graphene nanomaterial by using L ‐arginine as a linker; this material shows the unique Pt‐around‐SnO2 structure. The Sn2+ cations reduce graphene oxide (GO), leading to the in situ formation of SnO2/graphene hybrids. L ‐Arginine is used as a linker and protector to induce the in situ growth of Pt nanoparticles (NPs) connected with SnO2 NPs and impede the agglomeration of Pt NPs. The obtained Pt/SnO2/graphene composites exhibit superior electrocatalytic activity and stability for the ethanol oxidation reaction as compared with the commercial Pt/C catalyst owing to the close‐connected structure between the Pt NPs and SnO2 NPs. This work should have a great impact on the rational design of future metal–metal oxide nanostructures with high catalytic activity and stability for fuel cell systems. |
