Embodiment 1
[0025] ① In terms of volume ratio, prepare a mixed organic solvent according to the ratio of N,N-dimethylformamide: glacial acetic acid (DMF: HAc) = 6:4, the mixed organic solvent, LiAc·2H 2 O, tetrabutyl titanate mixed organic solvent by 10L, 200g LiAc 2H 2 O, the proportion of 2L tetrabutyl titanate is added to the hydrothermal reaction kettle in turn, the filling degree is controlled at 50% to 80% of the reaction kettle volume, and the stirring is even; then the hydrothermal reaction kettle is sealed and put into a dry In the box, control the hydrothermal temperature at 200±10°C, react for 20 hours, and naturally cool to room temperature after the reaction. The product obtained is washed repeatedly with absolute ethanol until it is neutral, then suction filtered and dried. The obtained white powder is ultrafine Titanium dioxide nanoribbons;
