Abstract

Proper design of support materials is an important approach to improve the utilization efficiency and regulate the electronic properties of Pt electrocatalysts. Herein, we have successfully prepared ultrathin WO₃ nanosheets by Ar plasma exfoliation as a support to anchor Pt nanoparticles. Owing to the unique structure, both electronic and physical interactions between Pt and WO₃ nanosheets are significantly modulated, resulting in enhanced electrocatalytic activity for methanol oxidation.
