PdAu nanoparticles anchored on P and Se codoped carbon support as an efficacious electrocatalyst towards glycerol electrooxidation

Abstract

• A novel P and Se codoped-carbon (P–Se–C) support is developed. • Strong SMSI exists between P–Se–C support and PdAu NPs. • Obtained PdAu/P–Se–C has a favorable GOR performance. 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 Pd n Au ( 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 Pd n Au alloy nanoparticles, a series of Pd n Au/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. PdAu nanoparticles anchored on P and Se codoped carbon support as an efficacious electrocatalyst (the arrow) towards Glycerol Electrooxidation. (i) PdAu (the arrow head) expresses the active part; (ii) P–Se–C (the arrow tail) can trigger more sites for PdAu NPs anchoring.
