摘要 对不同晶型纳米二氧化钛的合成方法和及其形貌控制作了简要综述 .前驱体的种类和浓度 ,溶剂的极性 ,pH值 ,反应温度 ,添加剂等反应条件对所得纳米二氧化钛的晶型 ,颗粒大小及形貌有很大影响 .通过选择不同种类的模板剂和控制反应条件可以制得具有不同晶型的介孔二氧化钛 . this paper makes a brief review on the synthesis of nanostructured titania with different crystallinities and controlling of their morphology. Experimental conditions, which involve both the type and concentrations of the precursors, polarity of the solvent, pH, reaction temperature, additive, etc, have important effect on crystallinity, particle size and morphology of the obtained titania. Mesoporous titania with different crystallinities has been synthesized under different conditions by choosing different template agents.
