Microwave synthesis and characterization of Pt nanoparticles supported on undoped nanodiamond for methanol electrooxidation

► Undoped nanodiamond (ND) is used as a new stable catalytic support material. ► Pt particles are loaded on ND's surface with microwave-assisted polyol method. ► Pt particles are small and uniform in size, and highly dispersed on ND supports. ► Pt/ND exhibits a good electrocatalytic performance for methanol oxidation.
