The invention discloses a doped visible light catalytic net and a preparation method thereof, comprising: step 1, adding tetrabutyl titanate to an organic solvent containing a hydrolysis inhibitor, and after dissolving, adding silicon-containing raw materials and iron salts in sequence to carry out Doping with silicon and iron, and stirring to obtain solution A; dissolving the pore-forming agent in water, and diluting with absolute ethanol to obtain solution B; the silicon-containing raw materials include ethyl orthosilicate, silicon tetrachloride, ortho-silicon methyl acid and propyl orthosilicate; step 2, under the condition of continuous stirring, add solution B dropwise to solution A, continue stirring for 1 to 5 hours, and obtain titanium dioxide sol after aging; step 3, add the acid solution treated The metal mesh is immersed in the titanium dioxide sol, pulled, dried, and then calcined at 200-1000° C. for 0.5-10 hours to obtain the doped visible light catalytic mesh. The doped visible light catalytic net of the present invention solves the problem that the titanium dioxide powder is difficult to separate and recycle during use, and has the ability of photocatalytic degradation under visible light. |
