Pt₂CeO₂ Heterojunction Supported on Multiwalled Carbon Nanotubes for Robust Electrocatalytic Oxidation of Methanol.

ABSTRACT: Herein, we prepared Pt₂CeO₂ heterojunction nanocluster (HJNS) on multiwalled carbon nanotubes (MWCNTs) in deep eutectic solvents (DESs) which is a special class of ionic liquids. The catalyst was then heat-treated at 400 °C in N₂ (refer to Pt₂CeO₂/CNTs-400). The Pt₂CeO₂/CNTs-400 catalyst showed remarkably improved electrocatalytic performance towards methanol oxidation reaction (MOR) (839.1 mA mg_Pt^-1) compared to Pt₂CeO₂/CNTs-500 (620.3 mA mg_Pt^-1), Pt₂CeO₂/CNTs-300 (459.2 mA mg_Pt^-1), Pt₂CeO₂/CNTs (641.6 mAmg^-1) (the catalyst which has not been heat-treated) and commercial P
