Understanding of the various factors that influence the catalytic activity of the electrocatalysts can give a guideline on designing and developing advanced catalysts for fuel cells. In the present paper, we have investigated on the fundamental understanding of the origin of the enhanced ORR activity of the bimetallic PdxCo100x (x = 100, 70, 50, and 30) nanoparticles utilizing a borohydride reduction method with various heat treatments. In order to identify the intrinsic understanding, various state of the art X-ray analyses were used, including inductively coupled plasma-atomic emission spectrometer, transmission electron microscopy, high resolution powder diffractometer, and high resolution photoemission spectroscopy. |
