摘要：

In this paper, we report the synthesis and characterization of nanoparticles (NPs) of a PtxY alloy supported on a commercial mesoporous carbon (MC). The NPs were prepared following a solid state synthesis in a quartz tubular furnace under H-2 flow. The influence of Pt precursors on the NP shape and alloy formation was investigated together with the temperature and reaction time. The best synthesis afforded the obtainment of small spherical PtxY NPs (4 nm diameter) on the surface and inside pores of a MC with a maximum of alloy content of 41% with respect to the whole Pt loading. The electrochemical properties of PtxY NPs were investigated with special attention to their catalytic properties. The results in ORR studies showed that the catalyst containing the highest amount of PtxY alloy exhibits higher catalytic activity expressed in terms of mass and specific activity and comparable stability, after accelerated degradation tests, for oxygen reduction as compared to a standard Pt/C catalyst.
