Pt nanocrystals grown on three-dimensional architectures made from graphene and MoS2 nanosheets: Highly efficient multifunctional electrocatalysts toward hydrogen evolution and methanol oxidation reactions

A facile and cost-effective co-assembly approach is developed to synthesize Pt nanocrystals grown on 3D architectures built from ultrathin graphene and exfoliated MoS2 nanosheets. Owing to their attractive structural features, the resulting hybrids exhibit multifunctional electrocatalytic ability toward hydrogen evolution and methanol oxidation reactions.359
