text: Acetaldehyde (CASRN 75-07-0) is a VOC with the formula CH 3 CHO.
text: Thus, due to having a higher dipole moment, the number of molecules of acetaldehyde that were adsorbed on the surface of the gas sensor was more than that of other gases [ Since acetaldehyde is a VOC and there are some other VOCs with almost the same formula, it is very difficult to gain high selectivity to acetaldehyde in metal-oxide-based gas sensors; however, some strategies such as optimization of the sensing temperature, noble metal decoration, doping, use of heterojunctions and use of membranes can enhance the selectivity to acetaldehyde.
