This work has dealt with the efficient degradation of styrene in a reactor system comprised of non-thermal plasma and Pd/ZSM-5 catalyst at room temperature. The problems regarding the individual plasma and catalytic processes such as poor low-temperature activity of the catalytic process and incomplete oxidation of the plasma process were complemented by the combination of both. The results demonstrated that the plasma-coupled Pd/ZSM-5 catalyst significantly enhanced both the styrene oxidation and the CO2 selectivity as compared with the plasma-alone case, greatly reducing the byproducts. The styrene degradation efficiency proportionally increased with increasing the specific input energy. Ozone formed by the plasma played an important role in the oxidation of styrene. The Pd/ZSM5 catalyst could be activated by the plasma, which greatly enhanced the performance for the styrene removal.

在 Pd/ZSM-5 催化剂上非热等离子体催化系统中苯乙烯的有效降解

这项工作涉及在室温下由非热等离子体和 Pd/ZSM-5 催化剂组成的反应器系统中苯乙烯的有效降解。单独的等离子体和催化过程的问题，例如催化过程的低温活性差和等离子体过程的不完全氧化，通过两者的结合得到了补充。结果表明，与单独使用等离子体的情况相比，等离子体偶联的 Pd/ZSM-5 催化剂显着提高了苯乙烯氧化和 CO2 选择性，大大减少了副产物。苯乙烯降解效率随着比输入能量的增加而成比例地增加。等离子体形成的臭氧在苯乙烯的氧化中起重要作用。Pd/ZSM5 催化剂可以被等离子体激活，
