Abstract

Abstract: Al₂O₃ supported CuO-MnO₂ catalysts were prepared via immersion method, and their structures were characterized with SEM and XPS techniques. The effect of the preparation methods and conditions on the catalytic activities were studied and the best reaction conditions was obtained. The results show that the catalysts of CuO-MnO₂/Al₂O₃ have very high catalytic activity, when the immersion time is 5 h, the molar ratio of Cu(NO₃)₂ to Mn(NO₃)₂ is 3∶1, and the catalyst was dried at 70 ℃ for 2 h and roasted at 200 ℃ for 3 h.

Key words: Catalytic ozonation, CuO, MnO₂, Catalyst
