Title: Preparation,Structural Characterization and Catalyst Activity of CuO-MnO_2/Al_2O_3 Catalysts
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.
