| 摘 要： | 钛酸丁酯作为前驱体,Span80、Span85和TritonX-114作为模板剂合成介孔二氧化钛,以氮吸脱附方法表征材料织构特性,以光催化丙酮研究材料孔结构对光催化性能的影响。结果表明,模板剂用量和种类对孔结构和光催化性能有较大的影响。直通孔道结构的二氧化钛比狭缝或墨水瓶孔道的二氧化钛具有更好的光催化活性,大的比表面积和孔径也有利于光活性的提高。

| Abstract: | Mesoporous TiO2 with different textural properties was synthesized using tetrabutyl titanate as the precursor and Span80, Span85 as well as Triton X-114 as the structure-directing agents. Textural properties were characterized using N2 adsorption/desorption methods. Photocatalytic activity was determined using acetone as the reactant to study the influence of pore structure on the photocatalytic capability. The results show an evident effect of the type and amount of surfactant on the pore structure and pho... |
