Porous Pt-M (M = Cu, Zn, Ni) nanoparticles as robust nanocatalysts

Porous Pt-M (M = Cu, Zn, Ni) nanoparticles (NPs) were obtained by reduction of [Pt(CH3NH2)(4)][PtCl4] and M(Ac)(2) (or MCl2) with oleylamine under mild conditions. The porous Pt-Cu NPs exhibited superior catalytic activities over a Pt/Cu NP mixture and Cu NPs as references for CO oxidation processes.
