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。 Titanate as precursor, Span80, Span85 and TritonX-114 as mesoporous mesoporous titania were synthesized. The texture properties were characterized by nitrogen adsorption and desorption. The effects of pore structure on photocatalytic activity were studied by photocatalytic acetone. The results showed that the amount of template agent and the type of pore structure and photocatalytic properties have a greater impact. Titanium dioxide with through-cell structure has better photocatalytic activity than titania with slits or inkwell openings. The large specific surface area and pore size also contribute to the enhancement of photoactivity.
