| Abstract: | In this paper, a preparation of Ag 2CO 3-TiO 2 catalyzer was posed. The reacting rate can be evaluated by the degradation velocity of carmine. The results showed that the catalytical reactive rate of Ag 2CO 3-TiO 2 was three times faster than TiO 2. The optimal quantity of Ag 2CO 3 and catalyzer was determined by experiments. The catalytical mechanism of Ag 2CO 3-TiO 2 was discussed. |
