The invention relates to the technical field of titanium dioxide preparation, and particularly relates to a preparation method of high visible light response aqueous high dispersion titanium dioxide. The method comprises the following steps: (1) mixing a titanium source and a solvent, adding concentrated hydrochloric acid, and stirring to obtain a transparent liquid; (2) and (2) adding the doping auxiliary agent into the transparent liquid obtained in the step (1), stirring, and transferring into a reaction kettle for reaction to obtain a titanium dioxide concentrated solution. The invention provides a preparation method of high visible light response aqueous high dispersion titanium dioxide, the prepared titanium dioxide has high dispersibility in water, can be excited under visible light to generate photocatalytic reaction, and can be used for various aspects such as sewage treatment, atmosphere purification, self-cleaning materials and the like. |
