The invention belongs to the technical field of material preparation processing, and concretely relates to a controllable nanocrystalline TiO2 particle, and a preparation method and a use thereof. A technical problem to be solved in the invention is to provide the preparation method of the controllable nanocrystalline TiO2 particle. The method comprises the following steps: 1, adding tetraisopropyl titanate into an acidic solution, and stirring and reacting to prepare a titanium sol; 2, carrying out a hydrothermal reaction on the titanium sol; and 3, removing the above obtained liquid phase after the hydrothermal reaction ends, washing until neutrality, and drying to prepare the nanocrystalline TiO2 particle. TiO2 particles with different morphologies, sizes and crystal forms can be prepared through the method as needed.
