| 摘 要： | 以四氯化钛为前驱体,采用水解沉淀法在海泡石粉体上负载纳米TiO2,从而制备纳米TiO2-海泡石复合材料,并以罗丹明B废水为降解对象,通过试验研究各种影响因素对纳米TiO2-海泡石复合粉体材料光催化性能的影响。结果表明:当各影响因素在适当的反应条件下时,纳米TiO2-海泡石复合粉体材料对罗丹明B废水的光降解率达到95%以上。

| Abstract: | TiO2 nano-particles were loaded on the supporting body of sepiolite particles by the hydrolysis precipitation method using TiCl4 as precursor and the nano-meter TiO2-sepiolite composite powder was prepared. The influence of the elements on the photocatalytic activities of TiO2 films were investigated by the degradation of rhodamine B. The results indicated that the degradation rate of the composite powder for rhodamine B was more than 95% in the proper conditions. |
