NO2 sensing performance of SnO2 hollow-sphere sensor

Abstract This work examined the possibility of using SnO 2 hollow spheres mediated by carbon microspheres for the efficient detection of NO 2 gas. The influences of gas concentration, operating temperature, crystallite (grain) size and structure feature on the sensing performance of the sensors based on SnO 2 hollow spheres were comprehensively studied. The SnO 2 hollow spheres had a mean crystallite size of 12.7, 14.1 and 22.8 nm when calcined at 450, 500 and 550 °C, respectively. It was found that the SnO 2 hollow spheres calcined at 450 °C with a crystallite size of 12.7 nm were the most sensitive to NO 2 gas. The sensor also had a better selectivity to NO 2 than to ethanol, methanol, gasoline, acetone, CCl 4 and NH 3 when operated at 160 °C.
