Abstract

Pore-loaded WO₃ nanofibers (NFs) functionalized with spherical catalyst films were achieved via electrospinning combined by the sacrificial templating route using layer-by-layer (LbL) catalyst assembled polystyrene (PS) colloids. The catalyst-loaded porous WO₃ NFs exhibited significantly improved toluene and acetone detection capability for potential application in exhaled breath analysis.
