Abstract
In this work, ZnO was decorated onto SnO2 microspheres via a facile solvothermal method, and the gas sensing characteristics of the ZnO/SnO2 composites was systematically studied. Results showed that the ZnO/SnO2 composites was highly responsive to NO2, with much lower response to interfering gases such as ethanol and acetone. At the optimum temperature (200 °C), the response of the ZnO/SnO2 composite to 100 ppm NO2 was about 3 times higher than that of pristine SnO2 microspheres. Furthermore, ZnO decoration on SnO2 microspheres led to significant reduction in the response time. The improvement of gas-sensing performance may be ascribed to the formation of more surface adsorption sites on the ZnO/SnO2 composite.
