In this work, we prepared porous WO3 nanofibers (NFs) functionalized by bio-inspired catalytic and nanoparticles as highly sensitive and selective gas sensing layers. Highly porous 3-dimensional (3D) NFs networks decorated by well-dispersed catalyst NPs exhibited superior gas response ( = 46 at 5 ppm) in high humidity environment (95 %RH). In particular, the sensors showed outstanding selectivity against other interfering analytes (such as acetone, toluene, CO, , ethanol). Exhaled breath sensors using and catalysts-loaded NFs are highly promising for the accurate detection of halitosis.
