Hierarchical structure SnO(2) supported Pt nanoparticles as enhanced electrocatalyst for methanol oxidation

Hierarchical structure SnO(2) with two-dimensional (2D) nanosheets building blocks was employed as support material for Pt nanoparticles (NPs). The SnO(2) supported Pt catalyst was synthesized through a facile aqueous phase process using sodium borohydride as the reducing agent. The as-prepared Pt-S...

Summary:Hierarchical structure SnO(2) with two-dimensional (2D) nanosheets building blocks was employed as support material for Pt nanoparticles (NPs). The SnO(2) supported Pt catalyst was synthesized through a facile aqueous phase process using sodium borohydride as the reducing agent. The as-prepared Pt-SnO(2) catalyst exhibited remarkably improved electrocatalytic activity and stability toward methanol oxidation, in comparison with that of the commercial Pt/C catalyst and the commercial SnO(2) nanopowder supported Pt catalyst. The superior catalytic performance may arise from the unique multiscale structure and morphology of the SnO(2) support, which process extraordinary promotional effect on Pt catalyst.
