负载型钙钛矿la0.8sr0.2mno3/sba-15催化燃烧甲苯的研究
, PP. 1142-1146
Keywords: 钙钛矿,la0.8sr0.2mno3,sba-15,甲苯,孔道内氨/水蒸气原位羟化法
Abstract:
？采用逐层负载-孔道内氨/水蒸气原位羟化法制备了一系列负载型钙钛矿la0.8sr0.2mno3/sba-15催化剂,用xrd、bet、tg-dtg、xps、h2-tpr等手段对催化剂的物性结构等进行了表征,并在常压连续流动固定床反应器上评价了该催化剂对甲苯催化燃烧的催化性能。结果表明,逐层负载-孔道内氨/水蒸气原位羟化法的使用有助于活性组分la0.8sr0.2mno3进入sba-15的孔道,并在sba-15上形成钙钛矿结构。la0.8sr0.2mno3/sba-15上钙钛矿结构的形成和晶格氧的出现,可为催化剂提供较多的活性中心,有利于其催化燃烧甲苯的活性。
