Preparation of PtNi/C electrocatalysts for direct methanol fuel cell via pulse microwave assisted polyol method

Abstract

PtNi/C nanoparticles with different atomic ratios of Pt/Ni were produced in pulse microwave assisted polyol process. Transmission electron microscopy (TEM) images show uniform morphology. X-ray diffraction( XRD) pattern plus energy dispersive X-ray (EDX) spectroscopy suggests pure composition. Cyclic voltammogram study reveals that PtNi/C nanoparticles synthesized in pulse microwave assisted polyol process have better catalytic activity for the oxidation of methanol to carbon dioxide than those synthesized in continuous process.
