• The decomposition rate of toxic acetonitrile (CH3CN) in the presence of SnO2 sensor elements was greatly affected by the addition of a Pd dopant. When the PdCl2 was doped into the SnO2 sensor elements, the oxidation reaction was predominant owing to both the enhanced oxygen adsorption and the effective oxygen supply in the presence of Pd catalysts. To clarify such effects, we analyzed the mechanisms of the reaction between CH3CN gas and the PdCl2-doped SnO2 elements using gas chromatography. From the results of the analysis of the decomposition products of CH3CN gas in the presence of the doped SnO2 sensor elements, we suggested a possible surface reaction mechanism of acetonitrile gas decomposition.
