本文研究碳纳米管改性TiO2光催化剂的制备和影响其光催化性能的因素.实验结果表明,CNT的加入方法,CNT的含量,催化剂的灼烧温度等均影响光催化剂的光催化性能.制备的CNT-TiO2光降解低浓度的甲胺膦农药(40.71mg/L)具有很好的效果,光催化降解过程符合一级反应动力学方程.

Specific surface area, pore structure and its adsorption behaviors of CNT were characterized.CNTTiO2 was prepared by using solgel method to enhance the catalytic activity of TiO2. The factors influencing its photocatalytic character and degradation of methamidophos were discussed in this paper.As a result, the CNT doped methods,CNT content, and calcination temperature affect the photocatalytic character of CNTTiO2. CNTTiO2 was used for degradation of methamidophos (initial concentration is 4071mg/L)in aqueous solution, and the...
