Core-shell hierarchical WO2/WO3 microspheres as an electrocatalyst support for methanol electrooxidation.
Core-shell WO2/WO3 microspheres were prepared using a phase transformation route. The as-prepared Pt-WO2/WO3 catalyst exhibits excellent activity and stability towards methanol electrooxidation, compared with those of commercial PtRu/C and Pt/h-WO3, due to the decrease of the electron-transfer resistance by the modification of using WO2 as a conductive oxide.
