Abstract

original image

A novel structural Pt/C-CeO2 catalyst synthesized using MP-CeO2 coated with carbon by in situ β-cyclodextrin carbonization and then depositing Pt nanoparticles using a fast and facile microwave-assisted polyol process. The increased electron conductivity and the more oxygen-containing species of carbon available for the Pt site contribute to the improved activity and stability for methanol oxidation compared to Pt/CeO2.
