...When the SnO2 sensor was exposed to a reducing gas (HCHO), the adsorbed oxygen ions (O2 , O − or O2 ) at the SnO2 grains boundaries are removed for oxidizing with HCHO molecules, and electrons were transferred back into the conduction band of the SnO2, leading to increase conductivity of SnO2 materials [38]....

...The sensor response (S) to a test gas was defined as the relative percentage change of the resistance, calculated as, response (%) = [((Rg − Ra)/Ra)×100] [29], where Rg and Ra denote the resistance of the sensor when exposed to target gas and ambient air, respectively....
