摘要：

Pt-based nanodentries (NDs) have received substantial interest in catalysis because of their superior catalytic features. Herein, triple-layered Rh@Co@Pt-skin core-shell NDs (Rh@Co@Pt-skin NDs) were obtained by successive co-reduction of the Rh, Co and Pt salts in oleylamine (OAm) with the assistance of creatinine and cetyltrimethylammonium chloride (CTAC). The Rh@Co@Pt-skin NDs exhibited remarkable increase in the catalytic characters such as the more positive onset potential (E-onset) and the greater mass activity (MA) towards oxygen reduction reaction (ORR) than commercial Pt/C, homemade PtCo nano-particles (NPs), CoRh nanoflowers (NEs) and PtRh NDs. This work provides some novel insights for synthesis of advanced nanoassemblies as efficient and robust electrocatalysts in fuel cells. (C) 2019 Elsevier Ltd. All rights reserved.
