Beschreibung
Zusammenfassung:	The invention discloses a preparation method of a titanium dioxide photocatalyst. The method comprises the following steps: dissolving water-soluble carbohydrate and water-soluble macromolecules into water in a closed container, adding with organic acid or alkali, and then adding with a soluble titanium salt, and reacting at 140-300 DEG C, dewatering and calcining, so as to obtain the titanium dioxide photocatalyst. The titanium dioxide photocatalyst is cheap and easily available in raw material, and simple in preparation method; with three-dimensional net carbon aerogel as a template, a silver halide-doped titanium dioxide photocatalyst is hotly synthesized by a one-pot method; and the obtained titanium dioxide photocatalyst is good in crystallization degree, uniform in size and high in catalytic efficiency in a visible light region, and can be applied to degradation of organic pollutants.
