Method of preparing anatase structured highlight catalytic active nano-TiO2

The invention discloses a preparation method for a high photo-catalytic activity nano-TiO2 with anatase structure, which comprises the following steps: (1) weighing organic titanium compounds or titanium inorganic salt which is dissolved in glacial acetic acid to prepare the mixed solution and dissolving the mixed solution in anhydrous alcohol to obtain solution 1; (2) selecting two or three templates, dissolving the templates in the anhydrous alcohol to obtain solution 2; (3) mixing the solution 1 and solution 2, adding distilled water, stirring, obtaining settled solution, standing for 2-5 days, forming gel and drying; (4) calcining the dried matter to remove the templates and obtaining the high photo-catalytic activity nano-TiO2 with anatase structure. The high photo-catalytic activity nano-TiO2 with anatase structure prepared by the method of the invention has smaller grain diameter smaller, larger specific surface and higher photo-catalytic activity than P-25, which can be widely used in the fields such
