Abstract

Abstract : Ultrasmall two-dimensional Pd55 Pt18 Co27 trimetallic alloy nanorings with enriched low-coordinated edge sites exhibit greatly enhanced ORR electrocatalytic activity. Abstract : Ultrasmall two-dimensional (2D) PdPtCo trimetallic nanorings (NRs) with enriched low-coordinated edge sites were facilely synthesized through a template-directed approach. The resulting Pd55 Pt18 Co27 NRs/C, featured with the highest edge to surface ratio and optimized composition, exhibits obviously enhanced oxygen reduction reaction (ORR) electrocatalytic activity.
