AbstractPopcorn-like PtAu nanoparticles were fabricated by a facile and green one-pot wet-chemical method, where H2PtCl4 and HAuCl4 were simultaneously reduced by glucosamine in alkaline media. The PtAu nanoparticles were further supported on reduced graphene oxide by simple ultrasonication. The nanocomposites showed an enhanced catalytic performance toward oxygen reduction reaction (ORR), dominated by a four-electron pathway, in comparison with Pt-rGO and commercial 10% Pt/C catalysts. Meanwhile, the nanocomposites displayed improved electrocatalytic properties and better stability for methanol oxidation over Pt-rGO and commercial Pt/C catalysts.; Popcorn-like PtAu nanoparticles were fabricated by a facile and green one-pot wet-chemical method, where H2PtCl4 and HAuCl4 were simultaneously reduced by glucosamine in alkaline media.
