| 摘 要： | 采用实验室合成的掺锡TiO2作为光催化剂，以罗丹明B降解反应为模型，研究了不同制备条件(反应时间、反应温度、氨水用量和掺杂量)和不同反应降解体系(催化剂用量、pH值)对掺锡TiO2降解罗丹明B的影响,实验结果表明，不同制备条件对产品的光催化活性有较大的影响，是决定产品光催化活性的关键因素,催化剂用量对罗丹明B降解起双重作用,酸性强的反应体系有利于罗丹明B的降解。

| Abstract: | The various affecting factors on sunlight degradation of Rhodamine B in the presence of doped-Sn TiO2 photocatalyst were studied.The results show that different preparation conditions,induding reaction temperature and time,the use level of aqua ammonia and doping-Sn amount,bring about important effect on catalytic activity of photocatalyst and were key factors to photocatalytic activity of doped-Sn titania.In addition,the number of catalyst had double-effect on degradating Rhodamine B. The degradation rate of Rhodamine B in the strongly acidic solution was higher. |
