The oxophilic and electronic effects on anchored platinum nanoparticles on sp2 carbon sites: The hydrogen evolution and oxidation reactions in alkaline medium

Abstract The impact of sp 2 sites of amorphous carbon and carbon nanotubes toward the hydrogen evolution/oxidation reactions on Pt nanoparticles, in alkaline medium, is described. The kinetic enhancement is given through the induced UV-photons of selectively photo-deposited platinum nanoparticles (Pt NPs) onto sp 2 domains. The, henceforth, induced sp 2 strong metal support interaction favors the electronic, and the oxophilic effects boosting the kinetics of hydrogen reactions.
