二噁英类含氯挥发性有机物（Cl-VOC）是毒性很强的环境污染物,为了筛选用于催化燃烧Cl-VOC的高效、稳定的催化剂,采用共沉淀法制备了（Fe、Co、Cu、V）-Mn催化剂,并负载于堇青石载体上,用邻二氯苯作为模型化合物对其催化性能进行评价,结果发现Cu-Mn/堇青石催化剂对气相邻二氯苯的催化燃烧性能最好。XRD结果显示Cu-Mn/堇青石催化剂煅烧之后有新的尖晶石CuMn2O4晶相出现;SEM结果表明Cu-Mn/堇青石催化剂颗粒分散均匀;反应前后EDS对比结果表明,反应后催化剂表面残留有少量氯,但是,寿命测试表明持续反应20h,邻二氯苯的降解率能稳定在65%,说明Cu-Mn/堇青石催化剂用于催化燃烧含氯有机挥发物具有较好的应用前景。

Volatile organic compounds contained chlorine（Cl-VOC） like dioxins is a kind of highly toxic gas phase environmental pollutants.For the purpose of choosing high efficiency and stable catalysts which is used for catalytic combustion of Cl-VOC,a series of（Fe,Co,Cu,V）-Mn catalysts supported on cordierite were synthesized and used for catalytic combustion of o-dichlorobenzene.The results showed that Cu-Mn/cordierite catalyst had the best catalytic performance in all catalysts.XRD results indicated that a new CuMn2O4 spinel phase presented in the Cu-Mn/cordierite catalyst and SEM results demonstrated that the particle distributed well.However,EDS results showed that the catalyst after reaction had a small amount of residual chlorine on its surface compared with before reaction.Further stability test result demonstrated that the degradation rate of o-dichlorobenzene is about 65% after 20h continued reaction,which showed that Cu-Mn/cordierite catalyst maybe have a good promise for catalytic combustion of volatile organic compounds contained chlorine.
