A one-pot route for the synthesis of Au@Pd/PMo₁₂/rGO as a dual functional electrocatalyst for ethanol electro-oxidation and hydrogen evolution reaction.

ABSTRACT: An in situ one-pot synthetic route for the synthesis of a Au@Pd/PMo₁₂/reduced graphene oxide (rGO) nanocomposite is presented, where the Keggin-type polyoxometalate phosphomolybdic acid (PMo₁₂) is used as both reducing and stabilizing agent. High-angle annular dark-field scanning transmission electron microscopy (HAADT-STEM), transmission electron microscopy (TEM), and X-ray diffraction analysis were applied to fully characterize the core-shell structure of Au@Pd/PMo₁₂ on the rGO matrix. Electrochemical studies showed how this nanocomposite acts as a dual electrocatalyst for the ethanol electro-oxidation reaction (EOR) and the hydrogen evolution reaction (HER). For the EOR, the Au@Pd/PMo₁₂/rGO electrocatalyst offers a low onset potential o
