研究了水解催化剂（HCl和C5H8O2）对凝胶法制备纳米TiO2粉体结构的影响。HCl催化的凝胶的结晶温度比C5H8O2催化的凝胶的结晶温度低约200 K。但在后一种凝胶中，金红石相在较低的温度下转变为金红石相，并且转变在更窄的温度范围内完成。
Effect of hydrolysis catalysts (HCl and C5H8O2) on structural evaluation of gelderived nanocrystalline TiO2 powders was studied. Crystallization temperature of the HCl catalyzed gel is about 200 K lower than that of the C5H8O2 catalyzed one. But in the later gel the anatase phase transforms to rutile at a lower temperature, and the transformation is completed in a much more narrow temperature range.
