摘要： 采用多孔树脂和钛酸四丁酯为起始物制备出碳掺杂的纳米TiO2 (RN700A550). 该材料的SEM和比表面积测定表明, RN700A550具有与P25类似的高分散性,这归于多孔树脂的存在强烈限制了纳米粒子的团聚. 另外,多孔树脂的使用还造成了样品的碳掺杂(大约1.0%). 罗丹明B的光降解实验表明, RN700A550不仅在可见光而且在紫外光激发条件下都显示了比P25更高的光催化活性.

Abstract: Carbon-doped TiO2 with large surface area has been successfully synthesized b y h ydrolysis of tetrabutyl titanate in the pores of resin and calcination in nitrog en and air. The use of resin not only realizes carbon doping in TiO2 but also li mits the aggregation of TiO2 nanocrystals. The carbon-doped TiO2 exhibits h igher activity than P25 under the irradiation of both visible and UV light.
