PdAu Nanoparticles Anchored on P and Se Codoped Carbon Support As an Efficacious Electrocatalyst Towards Glycerol Electrooxidation

To address increasingly energy and environment issues, fabricating some highly active and durable electrocatalysts by heteroatom-doped novel support materials substitutes are being actively pursued. Herein, a novel P and Se codoped-carbon (P-Se-C) is prepared as support for anchoring PdnAu (n refers to the molar Pd/Au ratio, n=1, 2, 3) alloy nanoparticles applied in glycerol electrooxidation reaction (GOR). Combined with the merits of P-Se-C support and PdnAu alloy nanoparticles, a series of PdnAu/P-Se-C show better catalytic activity and superior stability towards GOR relative to those of Pd/P-Se-C, Pd/Se-C and Pd/C. Thereinto, PdAu/P-Se-C (n=1) possesses the best catalytic performance towards GOR among as-obtained electrocatalysts. On account of all results, it is expected that the PdAu/P-Se-C would be a very suitable electrocatalyst towards GOR. (C) 2018 Taiwan Institute of Chemical Engineers. Published by Elsevier B.V.
