以苯酚-双氧水的氧化反应为探针,评价了Ti-SiZSM-5(TS-1)的催化性能,并对反应条件的影响进行了考察。研究表明,在适宜的条件下,TS-1表现出较高的催化活性、高的反应选择性和良好的活性稳定性。用NH_3-TPD和IR法对TS-1沸石的酸性进行了研究,发现TS-1只具有弱酸性。与反应结果进行关联,可知反应过程主要是沸石骨架中存在的结构在起催化活性中心作用,而不是酸催化。 The catalytic performance of Ti-SiZSM-5 (TS-1) was evaluated by the oxidation of phenol-hydrogen peroxide as a probe, and the influence of the reaction conditions was investigated. The results showed that under appropriate conditions, TS-1 showed high catalytic activity, high reaction selectivity and good activity stability. The acidity of TS-1 zeolite was studied by NH_3-TPD and IR. It was found that TS-1 only had weak acidity. Associated with the reaction results, we can see that the reaction process is mainly the existence of the zeolite framework in the catalytic activity of the center, rather than acid-catalyzed.
