Catalytic Oxidation of Volatile Organic Compounds on nano Zeolite Catalysts

In this study, catalysts containing 2.5 wt.% of copper were compared towards toluene total oxidation using ZSM5 nano- Zeolite and TiO2 (Degussa). A 2.5 wt.% CuHZSM5 was found to be promising catalysts for this reaction. Copper oxide had a better affinity for zeolite. The performances of Cu based catalyst was related to oxygen mobility property of the support leading to copper oxide particles easily reducible. Therefore, 2.5wt% Cu-ZSM5 samples were found to be interesting catalysts for total VOC oxidation.
