摘要：

Well-defined interconnected porous Pt nanospheres (Pt-IPNSs) with average diameter around 43 nm are constructed by a facile one-step hydrothermal process using polyallylamine hydrochloride (PAH) as a stabilizing agent and HCHO as a reductant. The morphology, size, integrity and formation mechanism of the Pt-IPNSs are investigated. The results demonstrate that the as-prepared Pt-IPNSs have three-dimensional porous nanostructures with primary interconnected nanoparticles around 4 nm as building blocks. Electrocatalytic measurements indicate that Pt-IPNSs could catalyze FAOR predominantly through dehydrogenation pathway with better tolerance to CO poisoning and durability compared with commercial Pt-black, probably due to the unique porous assembly structure.
