This work examined the possibility of using SnO2hollow spheres mediated by carbon microspheres for the efficient detection of NO2gas. The influences of gas concentration, operating temperature, crystallite (grain) size and structure feature on the sensing performance of the sensors based on SnO2hollow spheres were comprehensively studied. The SnO2hollow spheres had a mean crystallite size of 12.7, 14.1 and 22.8nm when calcined at 450, 500 and 550°C, respectively. It was found that the SnO2hollow spheres calcined at 450°C with a crystallite size of 12.7nm were the most sensitive to NO2gas. The sensor also had a better selectivity to NO2than to ethanol, methanol, gasoline, acetone, CCl4and NH3when operated at 160°C.
