| 摘 要： | 自行合成了Zn1.5PW12O40纳米管催化剂,在臭氧体系中进行了催化氧化苯胺的实验。通过对苯胺的降解考察了Zn1.5PW12O40纳米管催化剂的催化性能,利用GC/MS对催化反应的途径和机理进行研究,并通过重复实验验证催化剂的回收利用效果。结果发现:在Zn1.5PW12O40的催化下,臭氧对苯胺降解效果有明显的提高,在8 min之内去除率可由单独氧化时的85%提高到99%;其臭氧氧化机理以羟基自由基为主,催化剂的重复利用性较好。

| Abstract: | The self-synthesized nanotube Zn1.5PW12O40 catalyst was used in the ozone oxidation of aniline.The catalytic performance was investigated through the degradation of aniline.The catalytic reaction pathway and mechanism were explored by GC / MS.The recycle of catalyst was tested by repeatied experiments.The result showed that with the help of Zn1.5PW12O40,the degradation of aniline has increased significantly.The removal rate increases from 85% to 99% within 8 min.The main mechanism of oxidation is the hydroxyl radical.The recycled catalyst after activated has little change in its catalytic characteristics. |
