摘要
The Fe2O3 nanoparticles activated V2O5 nanotubes were achieved via a hydrolysis method. The TEM and SEM images of the nanotubes indicated that the Fe2O3 nanoparticles with the particle size of about 15 nm were dispersed on the surface of the V2O5 nanotubes. The activated nanotubes exhibited excellent response and selectivity towards the ethanol gas. The lowest detection limit for ethanol gas was about 10 ppm at 230 degrees C, which suggested that the Fe2O3 nanoparticles activated V2O5 nanotubes would be a potential candidate for practical detector for ethanol.
