摘要
本文是采用负载金属银对TiO2 改性后得到了载银TiO2 ,利用不同反应时间的胭脂红降解率反映光催化氧化反应的速率 ,结果表明 ,载银TiO2 比TiO2 的催化反应速率提高了 3倍。通过实验确定最佳含银量和催化剂最佳投加量 ,并讨论了载银TiO2 的催化机理 ,提出了制取载银TiO2 催化剂的方法。
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.
