Modulating the Digital framework of Pt is a highly effective strategy for improving the action and durability of Pt-primarily based electrocatalysts. Herein, we reported a variety of intermetallic CeO2/PtBi nanoplates (NPs), which possessed enhanced exercise check here and durability for methanol electro-oxidation reaction (MOR) by strong p-d hybridization involving the Pt and Bi. The surface-deposited CeO2 can even more enhance the electronic structure of Pt, even though furnishing much more hydroxyl adsorption sites. Exclusively, the CeO2/PtBi NPs exhibited outstanding mass action for MOR in each acidic and alkaline environments, which ended up 1.
