Highly sensitive and selective ethanol sensors using porous SnO2 hollow spheres
Source abstract
Abstract
Abstract Porous SnO 2 hollow nanospheres have been prepared by a direct precipitation method using carbon spheres as template. The structural and morphological are investigated by XRD, SEM, TEM and BET. Both of the formation and sensing mechanism have been discussed. Most importantly, the gas sensor based on these porous SnO 2 hollow nanospheres exhibited perfect sensing performance toward ethanol. The enhancement in gas sensing properties was attributed to their unique structures, including the large specific surface area (41.42 m 2 /g), hollow structure and porous feature. The results obtained in this study indicate that porous SnO 2 hollow nanospheres are potential candidates for fabricating effective ethanol sensors.
