80～90 DEG C it are warmed up under stirring condition, return stirring 6～18h, natural cooling, obtain stable transparent boehmite sol；
B, the preparation of complex sol
Under stirring condition, the mixed solution that tetrabutyl titanate that mol ratio is 1:20～100 and alcohol are made into is slowly added dropwise to
In a step gained boehmite sol, room temperature is stirred vigorously 1～3h, obtains homogeneous transparent complex sol；
Wherein, aluminum isopropylate. is 1:0.1～2 with the mol ratio of tetrabutyl titanate；
C, the preparation of loaded photocatalyst
After the complex sol of b step gained is sealed ageing 12～48h at normal temperatures, in the drying baker ventilated in 80～
Dry 6～8h, be then placed in Muffle furnace being heated to 450～550 DEG C for 100 DEG C, be incubated 3～5h, naturally cool to room temperature, finally
Grind the titanium dioxide optical catalyst obtaining the load of adsorbent class carrier gama-alumina；
Above-mentioned alcohol is ethanol, or isopropanol, or n-butyl alcohol, or propylene glycol；
Above-mentioned acid is hydrochloric acid, or nitric acid, or acetic acid, or oxalic acid.
The present invention is according in certain acid range, and boehmite sol is stable, and TiO 2 sol this characteristic of easy gel,
Use titania gel cutting boehmite sol, then prepare carrier and loaded article by high temperature sintering, it is achieved dioxy simultaneously
Change titanium and be carried on gama-alumina with chemical bond.Not only increase titanium dioxide in photocatalytic process with catalysis the contacting of object
Area, also gives the absorption property of catalyst gama-alumina, improves photocatalytic speed and the effect of titanium dioxide.
The present invention compared with prior art, has the advantage that:
1, the present invention is with aluminum isopropylate. and tetrabutyl titanate as primary raw material, prepares gama-alumina carried titanium dioxide light
Catalyst, as one of primary raw material preparing gama-alumina, aluminum isopropylate. price is relatively cheap, it replace gama-alumina
Directly prepare photocatalyst can reduce cost with tetrabutyl titanate.
2, in photocatalyst prepared by the present invention, titanium dioxide may be up to 2:1, greatly with the mol ratio of carrier gama-alumina
Improve greatly titanium dioxide load capacity on gamma-alumina.
3, photocatalyst prepared by the present invention, can be used for bisphenol-A, or methyl orange, or methylene blue, or Congo red, or sieve
The catalytic degradation of red bright gas chromatography, applied range.
4, the photocatalyst prepared by the present invention, after 8 times recycle, removes organic catalytic degradation in sewage
Rate, still more than 80%, can be used for organic catalytic degradation in sewage.
