- W2364148047 abstract "The platinum based alloy catalysts were prepared by aquous aggradation and high tempreture alloying method. The structure of the catalyst was studied by energy dissemination spectrum(EDS), X-ray diffraction(XRD). And the performances of catalysts in proton exchange membrane fuel cell (PEMFC) were tested. Results show that the platinum based alloy catalysts has a structure of face-center cubic, the atom ratio of platinum and transition metal is closed to 3:1, the prepared catalysts plays better performance than pure platinum, the activity order is Pt-Cr/CPt-Co/CPt-Ni/CPt/C. The effect of transition metal on the enhancement of catalytic activity was discussed. The result shows that the inducing of alloy element shorten the Pt-Pt distance, increases the d-vacancy of Pt, so it improves the performance of the catalysts." @default.
