Abstract
The invention relates to a method for preparing titanium dioxide, in particular to a method for preparing the titanium dioxide by utilizing a hydrothermal synthesis method. N-butyl titanate is added into an anhydrous alcohol solution, is evenly stirred, is slowly dripped with a carboxylic acid aqueous solution containing sulfhydryl groups and is acutely stirred for 20 to 60 minutes to obtain a transparent hydrothermal precursor solution. The precursor solution is added into a hydrothermal reaction kettle, is cooled to the room temperature and is taken out to obtain a nanometer titanium dioxide colloid solution. TiO2 prepared by the method can be applied to the fields of dye-sensitized solar cell, cosmetic, painting and the like.
