| 英文摘要 | To promote the commercialization of direct formic acidfuel cell(DFAFC), it is vital to explore new types of direct formic acid oxidation(FAOR) catalysts with high activity and direct pathway. Here, we reportthe synthesis of intermetallic platinum-lead/platinum nanoplatesinlaid with sub-monolayer antimony oxide surface (PtPb/Pt@sub-SbO x NPs) for efficient catalytic applicationsin FAOR. Impressively, they can achieve the remarkable FAOR specificand mass activities of 28.7 mA cm(-2) and 7.2 A mg(Pt) (-1), which are 151 and 60 times higher thanthose of the state-of-the-art commercial Pt/C, respectively. Furthermore,the X-ray photoelectron spectroscopy and X-ray absorption spectroscopyresults collectively reveal the optimization of the local coordinationenvironment by the surface sub-monolayer SbO x , along with the electron transfer from Pb and Sb to Pt, drivingthe predominant dehydrogenation process. The sub-monolayer SbO x on the surface can effectively attenuatethe CO generation, largely improving the FAOR performance of PtPb/Pt@sub-SbO x NPs. This work develops a class of high-performancePt-based anodic catalyst for DFAFC via constructing the unique intermetalliccore/sub-monolayer shell structure. |
