Description
Technical field
The present invention relates to a kind of chemical material technical field, more particularly to a kind of nano combined mineral matter except formaldehyde agent and its
Preparation method.
Background technology
In recent years, after interior decoration, ammonia that the formaldehyde in adhesive, the benzene homologues in paint, wall discharge etc. is changed
Learning pollutant can slowly be discharged for a long time, and indoor occupant health is constituted a serious threat.People stays in room can feel for a period of time
Dizzy, dizzy, breathing discomfort, the health of indoor occupant is directly affected, so, indoor environment is carried out after finishing comprehensive
Close and administer, be a urgent health engineering.In the prior art, indoor environment, solid are improved in order to remove ski dome
The products such as activated carbon, photocatalyst, formaldehyde lyase are current relatively widely used products.It is clear mainly by way of absorption
Except chemical pollutant, the chemical reactions such as oxidation, decomposition occur due to no, so elimination effect is not known.And the master of photocatalyst
It is titanium dioxide to want composition, and nano titanium oxide is stable, nontoxic and effectively can remove in air and water because of its chemical property
Pollutant and as solving the ideal material of the energy and environmental problem.However, larger (the Eg=of the energy gap of titanium dioxide
3.2eV), light-catalyzed reaction only could occur under ultraviolet light of the wavelength less than 387nm, it means that titanium dioxide can only profit
With a small amount of part in sunshine（About 5%）, and the visible ray (about 45%) being in the great majority in sunshine can not utilize.
Doping vario-property is titanium dioxide is had one of important means of visible light catalysis activity, although can realize can for metal ion mixing
See photocatalytic activity, but because metal ion turns into complex centre, make the catalytic activity of ultraviolet light wave band reduce.2001
Asahi etc. has found that nitrogen substitutes a small amount of Lattice Oxygen and the band gap of titanium dioxide can be made to narrow, active in the case where not reducing ultraviolet light
While make titanium dioxide that there is visible light activity so that turn into a big study hotspot for the doping vario-property of titanium dioxide,
Therefore the principle for removing depollution can be catalytically decomposed in visible ray using the titanium dioxide of doping, exploitation and composition is a visible
The photocatalyst formaldehyde agent for removing formaldehyde can be effectively decomposed under light.Current photocatalyst formaldehyde agent is general all only in the irradiation of ultraviolet light
