Reduced graphene oxide-supported tungsten carbide (WC/RGO) was prepared in a fine structure with nanocrystallites WC fixing on the layers of RGO. Pt and Ru nanoparticles were loaded on WC/RGO sequentially to synthesize electrocatalysts (Pt:Ru)n-WC/RGO via Cu underpotential deposition-redox replacement. Pt and Ru are supposed to present in the form of Pt-adatom and Ru-adatom layer by layer, which leads...
In this study, low loading platinum nanoparticles (Pt NPs) have been highly dispersed on reduced graphene oxide-supported WC nanocrystallites (Pt-WC/RGO) via program-controlled reduction-carburization technique and microwave-assisted method. The scanning electron microscopy and transmission electron microscopy results show that WC nanocrystallites are homogeneously decorated on RGO, and Pt NPs with...
