摘要
Gas-sensitive structures with nanoscale heterojunctions are formed by the co-deposition of WO3-x nanoneedles and Fe2O3 nanoparticles via aerosol-assisted chemical vapour deposition. These composite structures demonstrate enhanced gas sensor performance to ethanol, methanol, acetone, and toluene compared to bare WO3-x nanoneedles devoid of heterojunctions, with better selectivity for the group of analytes studied.
