And (3) after light-shielding adsorption for 30min and adsorption balance, using a 500W xenon lamp to irradiate for 2h for photocatalytic degradation, and testing the degradation rate.
Examples 1 to 5 show that when the titanium dioxide dispersion is doped with nitrogen: 2-hydroxy-4- (3-allyloxy-2-hydroxypropoxy) benzotriazole: the mass ratio of benzoyl peroxide is 2:4:2, the moisture regain and the formaldehyde degradation rate are the highest.
Comparative examples 1 to 3 show that when the nitrogen-doped titanium dioxide dispersion or 2-hydroxy-4- (3-allyloxy-2-hydroxypropoxy) benzotriazole content is too high, the polymerization tendency of the monomer increases; when the benzoyl peroxide content is too high, excessive initiation can be caused, more monomer free radicals are generated, and the monomer free radicals collide with each other to be deactivated, so that the photocatalytic performance is reduced, and the formaldehyde degradation rate is reduced.
The excessive doping of nitrogen element in comparative example 4 promotes the recombination of electrons and holes, and the holes cannot effectively adsorb H2O to generate hydroxyl radicals, so that the photocatalytic efficiency of titanium dioxide is reduced.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
