Highly Sensitive SnO2 Nanorods Ethanol Sensors with the Adsorption of Au Nanoparticles
Flower-liked SnO2 nanorods were prepared by a hydrothermal method. The sensors were fabricated using SnO2 nanorods adsorption of Au nanoparticles through sputtering deposition. We found that the loading of a small amount of Au nanoparticles on the surface of SnO2 nanorods can effectively enhance and functionalize the gas sensing performance of SnO2 nanorods, which due to the Au adsorption make the surface-depletion effect more pronounced. Such enhanced surface depletion increases the sensitivity, lowers the operation temperature and decreases the response time.
