A kind of preparation method of amorphous nanometer titanium dioxide photocatalyst |
| abstract |
The invention relates to a preparation method of an amorphous nano-titanium dioxide photocatalyst. The steps are: A. preparing metatitanic acid into a suspension of 600-800 g/L, adjusting the pH to 7-8 with 10% NaOH solution, The metatitanic acid slurry is prepared by stirring and dispersing; B. The metatitanic acid slurry is wet-ground with a sand mill for 2 to 3 hours; C. The metatitanic acid slurry after pressure filtration and grinding is washed again until the conductivity of the filtrate is less than 10 μs /cm, to obtain a filter cake; D. Dry the filter cake at 200-250° C. to obtain amorphous titanium dioxide; E. Perform airflow pulverization in a jet mill to obtain an amorphous nano-titanium dioxide photocatalyst. The amorphous nanometer titanium dioxide photocatalyst prepared by the invention has large specific surface area, good water dispersibility and low forbidden band width, is used for degrading pollutants, and has good photocatalytic performance under the condition of visible light irradiation . |
