| Abstract: | The supported catalysts of CuO over stannic oxidetitania mixed oxides (CuO/SnO2TiO2) have been prepared and tested for carbon monoxide oxidation in mixtures of carbon monoxide and air in feed gases by TPR method.The effects of preparation methods of the support,the mole ratio of stannic oxide and titania in mixed supports,calcination temperature as well as CuO loading upon the catalytic activity of CO oxidation were investigated.The results showed that,among the CuO/SnO2TiO2 catalysts,the most favorable one was prepared with the CuO loading of 10%15%,and the mole ratio of stannic oxide and titania of 40%.The added SnO2 have the synergistic ability in TiO2 support. |
