Influence of Pd and Au on Electrochemical Valorization of Glycerol over Ni-rich Surfaces

Abstract Herein we synthesized bi-metallic Pd@Ni and Au@Ni core-shell-like nanoparticles (NPs) for glycerol electrooxidation reaction (GEOR) in alkaline media. The morphological, structural and surface properties of the NPs were evaluated using a range of physicochemical techniques. The catalytic activity and stability were studied using the three-electrode electrochemical cell and 25 cm2- continuous electrolysis cell. Among different atomic ratios, Ni80Pd20 and Ni90Au10 nanoparticles showed the highest current densities which are ∼ 4.5 and 4.2 times higher than spherical Ni, respectively. The addition of Pd and Au (
