Vanadium doped tin dioxide as a novel sulfur dioxide sensor

Apr 15, 2008· The effect of V 2 O 5 doping on sulfur dioxide sensitivity of SnO 2 samples has been depicted in Fig. 5, where the percent sensitivity (percent response) is given by: (2) S = R A − R G R A × 100 where R A and R G are the sensor resistance in air and gas (at the operating temperature), respectively. It is found that SnO 2 sensor containing wt.% V 2 O 5 shows the highest sensitivity …
