摘要
合成了La2-x Ba x CuO4系列催化剂,应用一系列仪器测试结果分析得到,掺杂Ba量为0.6时在850℃催化NO活性最高。TG-DTA分析表明在450℃焙烧后样品中的有机组分完全消失。XRD结果显示了当x=1钙钛矿型为主相。H2-TPR研究结果显示催化剂活性与中心离子有很大关系。
La2-x BaxCuO4 series catalyst was synthesized. Application of a series of instruments test, through analysis, the results were obtained that the amount of doped Ba was 0. 6 in 850 ℃ and activity was the highest temperature. TG - DTA analysis showed that in 450 ℃ after roasting in a sample of organic components completely disappeared. XRD results showed that when x = 1 perovskite phase was the main phase. H2 - TPR results showed that the catalyst activity center ion had the very big relations.
