Abstract

Abstract: In this work, we put forward a simple and green strategy to design and synthetic a highly efficient Au@GQDs@Pt3.5 Bi nano-catalyst with a novel nanostructure composed of an Au@GQDs core and Pt3.5 Bi alloy shell. This material showed outstanding catalytic capability for the oxidation of methanol (MOR) than that of the commercial Pt/C catalyst. The sequence of the mass activity was arranged to be commercial Pt/C (0.29 A mgPt −1 ) < Au@Pt3.5 Bi (1.6 A mgPt −1 ) < Au@GQDs@Pt (1.81 A mgPt −1 ) < Au@GQDs@Pt3.5 Bi (17.45 A mgPt −1 ). The outcomes ascribed to the unique core-shell structure with dendrites, interior electronic and synergistic effect with Bi and Pt. This work enlightens on the delicate proposal of novel core-shell nano-material for improving the electro-catalytic performance of MOR.
