中文摘要：

文章通过回流法和固相法合成了隐钾锰矿八面体分子筛OMS-2催化剂,用BET-N2吸脱附曲线、X射线衍射、H2-TPR和透射电镜等方法对催化剂进行了表征。在常温常压下,将OMS-2催化剂涂覆在等离子放电管的余辉区,甲苯先经过介质阻挡放电（dielectric barrier discharge,DBD）得到初步降解;在余辉区,OMS-2吸附DBD产生的长寿命活性物种和臭氧进一步催化氧化甲苯。结果表明：OMS-2与DBD等离子体相结合可显著提高甲苯的转化效率;催化剂的合成方法对催化剂表面性质和催化氧化性能有显著影响,回流法制备的OMS-2对甲苯转化率（η）、CO2选择性、尾气中O3产生量及能量效率（Φ）等性能的影响表现更优异。

英文摘要：

Manganese oxide octahedral molecular sieve（OMS-2） for toluene catalytic combustion is syn- thesized by solvent-free solid-state and refluxing synthesis methods. BET-N2, XRD, H2-TPR and TEM techniques are applied to characterize catalysts. At room temperature and atmospheric pressure, the OMS-2 catalyst is coated on the afterglow section of the discharge tube. After the initial degrada- tion of toluene by dielectric barrier discharge（DBD）, OMS-2 can adsorb and catalyze long-lived active species and ozone produced by DBD for further removal of toluene. The results show that OMS-2 and DBD plasma can significantly improve the conversion efficiency Of toluene. Preparation method of cat- alyst has a significant impact on the surface properties and catalytic performance of catalyst. The OMS-2 catalyst prepared by refluxing method has excellent performance with regard to toluene remov- al efficiency（η）, carbon oxide selectivity, amounts of O3 in tail gas and energy efficiency（φ）.
