摘要 The effects of pH,temperature and stir rate on the coprecipitation of gas-sensitive Sn Zn Fe composite oxide were studied with the method of orthogonal experiment.The results showed that the gas-sensitive Sn Zn Fe composite oxides prepared in different reaction conditions were different to different gases.The coprecipitation conditions for preparing the Sn Zn Fe composite oxide were chosen for more sensitive to C 2H 5OH and H 2S.
