Abstract The non-heating gas sensing elements of SnO2 doped a-Fe2O3 and CeO2 have been prepared successfully. It indicates that the greater(142m2 / g) the specific surface area of gas sensing element is,the more the adsorbed OH- (O2-) is, thus the better the gas s

Key words: non-heating gas sensing element gas sensing mechanism
