介绍了各样模板及相关介孔制备体系,包含表面活性剂模板制备,非表面活性剂模板制备,其它模板制备及非模板制备。结果显示介孔结构可以很好的提高纳米TiO2的光催化活性,虽然在少数例子中介孔结构对光催化活性产生的影响很小或是没有影响。重点论述了上述研究方法的原理、优缺点和在改变TiO2性能中的应用,以及这些方法相结合所取得的一些研究进展;并指出这些方法在TiO2光催化剂的研究中发挥的重要作用。
Various templates and related mesoporous preparation systems are introduced, including preparations of surfactant templates, preparation of non-surfactant templates, preparation of other templates and preparation of non-templates. The results show that the mesoporous structure can improve the photocatalytic activity of nano-TiO2, although the mesoporous structure has little or no effect on the photocatalytic activity in a few cases. The principle, advantages and disadvantages of these methods and their applications in the modification of TiO2 properties are reviewed. Some progress made in the combination of these methods are also discussed. The importance of these methods in the research of TiO2 photocatalysts is also pointed out.
