Modulating the Digital framework of Pt is a good strategy for maximizing the exercise and toughness of Pt-dependent electrocatalysts. Herein, we noted a type of intermetallic CeO2/PtBi nanoplates (NPs), which possessed Increased activity and longevity for methanol electro-oxidation reaction (MOR) as a result of robust p-d hybridization between the Pt and Bi. The surface area-deposited CeO2 can even further optimize the Digital construction of Pt, although providing extra hydroxyl adsorption websites. Particularly, the CeO2/PtBi NPs exhibited superb mass exercise for MOR in both equally acidic and alkaline environments, which have been one.
