Graphical abstractA kind of mixed ionic liquids (ILs) of 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4], IL1) and hexafluorophosphate ([bmim][PF6], IL2) was introduced to the functionalization of graphene (GN) nanosheets, which was used to the synthesis of platinum nanoparticles (Pt NPs) to obtain the Pt/IL1-IL2/GN nanocomposite. The as-prepared Pt/IL1-IL2/GN composites exhibited highly electrocatalytic activity (764.3mA mg−1Pt at 0.6V vs. SCE) and stability toward methanol oxidation, demonstrating their promising potential as the anode catalyst for direct methanol fuel cells (DMFCs).
