Abstract

Ceria (CeO2) hollow fibers with Pt nanoparticles (Pt NPs) embedded in their inner surfaces were prepared by sequentially depositing Pt NPs and CeO2 sheaths on electrospun fibers of polystyrene, followed by calcination in air at 400 °C. Despite a relatively low Pt loading in this system, the turnover frequency for CO oxidation was 2-3 orders of magnitude higher than those of other systems, and the reactivity was also stable up to 700 °C.
