Comparative examples 1 to 3 show that when the content of the nitrogen-doped titanium dioxide dispersion or 2-hydroxy-4- (3-allyloxy-2-hydroxypropoxy) benzotriazole is too high, the monomer polymerization tendency increases; when the content of the benzoyl peroxide is too high, the over initiation is caused, more monomer free radicals are generated, and the radicals collide with each other to be inactivated, so that the photocatalytic performance is reduced, and the formaldehyde degradation rate is reduced.
In comparative example 4, excessive doping of nitrogen promotes recombination of electrons and holes, and H cannot be effectively adsorbed by holes 2 O generates hydroxyl radicals to reduce the photocatalytic efficiency of titanium dioxide.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
