Comparison of electrocatalytic activity of Pt_1-x Pd _x /C catalysts for ethanol electro-oxidation in acidic and alkaline media.

ABSTRACT: In this paper, a comparision of Pt_1-x Pd _x /C catalysts for ethanol-oxidation in acidic and alkaline media has been investigated. We prepared Pt_1-x Pd _x /C catalysts with different ratios of Pt/Pd (x at% = 0, 27, 53, 77 and 100) by the formic acid reduction method. The obtained Pt_1-x Pd _x /C catalysts were characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), induced coupled plasma-atomic emission spectroscopy (ICP-AES), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). Structural and morphological investigations of the as-prepared catalysts revealed that the metallic particle size increases with increasing Pd co
