Abstract

ceria hollow fibers

electrospinning

platinum nanoparticles

sinter resistance

Ceria (CeO ₂ ) hollow fibers with Pt nanoparticles (Pt NPs) embedded in their inner surfaces were prepared by sequentially depositing Pt NPs and CeO ₂ 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.
