摘　　要：用沉淀-沉积法制备了一系列x Au/La_2O_3催化剂,并采用H2-TPR方法表征了催化剂的还原性,并评价了催化剂丙烷低温完全燃烧催化性能。结果表明:沉积沉淀法制备的3%Au/La_2O_3催化剂,丙烷低温催化燃烧活性最好,起燃温度为300℃,完全转化温度为435℃。A series of xAu/La2O3 catalysts were prepared by deposition-precipitation method. The reducibility of the catalysts was characterized by H2-TPR technique. Their catalytic performances for the combustion of Propane had been investigated. 3%Au/La2O3 showed the highest catalytic activity, and its light-off temperature was 300℃ , complete conversion temperature was 435℃.
