The invention discloses a preparation method of a modified titanium dioxide catalytic film. Distilled water, modified TiO 2 to obtain modified titanium dioxide powder, then poured a certain amount of polyvinyl alcohol into a beaker, added deionized water and modified titanium dioxide powder, stirred, vacuum defoamed, and cast the composite sol coating Distribute to the mirror surface and dry to obtain the finished catalytic film. The beneficial effects of the invention are simple process, green and environmental protection, can be used for large-scale industrial production, high degradation efficiency of organic dye wastewater in the visible light range, and high practical value and application prospect. |
