Abstract
The invention discloses a kind of preparation method and applications of visible light catalytic coated fabric, it is adhesive that this method, which selects the neoprene rich in chlorine element, first it is coated onto fabric surface, photochemical catalyst titanium dioxide is sprayed into the fabric surface coated with adhesive again, photochemical catalyst is made to be stable at fabric surface.Neoprene, which makees adhesive, to be steadily fixed on fabric surface for titanium dioxide, and neoprene dechlorination, chloride ion is modified titanium dioxide simultaneously, part chloride ion, which can steadily be adsorbed on titanium dioxide surface, changed dramatically titanium dioxide surface charging property, promote titanium dioxide surface negatively charged, has preferably absorption to there is more preferably degradation property in the dye of positive ion.Part chlorine can enter titanium dioxide lattice and replace Lattice Oxygen, so that titanium dioxide generates oxygen defect, reduce titanium dioxide band gap and enhance absorption of the titanium dioxide to visible light, to improve TiO 2 visible light catalytic degradation performance.
Description
Technical field
The invention belongs to function fabric preparation and field of surface modification, are related to function fabric surface modified load photochemical catalyst
Preparation method, which is applied to other pollutants in photocatalytic degradation dyeing waste water and water body.
Background technique
With the rapid development of modern society's industry, the problem of environmental pollution is to become increasingly severe.Various water bodys are dirty
Dye such as comes from factory's organic dyestuff, in the waste water etc. of the generations such as synthetic paint, plastics, process hides, fabrication processes.Especially contain
The dyestuff of aromatic molecule structure is typically all to have good photostability and thermal stability.If these waste water from dyestuff cannot obtain
To being effectively treated, it will seriously destroy ecological environment, even threaten human health.Therefore, dyestuff is effectively removed from waste water
It is extremely important.There are many method for handling waste water containing dye, mainly there is absorption at present, flocculate, electrolysis, biodegrade and photocatalysis drop
Solution method.Wherein absorption method can be very good to remove dyestuff from waste water, but can not fundamentally solve dyestuff to ring
The harm in border.It is not the substance that dyestuff is decomposed into environmental sound because absorption only separates dyestuff with waste water.
Photocatalytic pollutant degradation technology is the means of the effective processing pollutant of one kind developed recently, it utilizes ultraviolet
For light even sunlight as the energy, vitalizing semiconductor catalyst generates strong oxidizing property free radical, in the water that can successfully degrade
Most of organic matters.Its operating cost is low, is a kind of high-efficiency energy-saving technology, has a good application prospect.TiO2Photocatalysis
Agent is widely used at present, it has the advantages that high chemical stability, nontoxic, inexpensive, high activity.But it there is
The disadvantages of forbidden band is wider, quantum yield is lower, weak to pollutant adsorption capacity, solid powder particle is small easy to reunite.In addition TiO2
Photocatalysis does not absorb visible light and after the completion of degradation of contaminant, and nano-photocatalyst can not recycle, limit they
Applicability in true water treatment system.Therefore, pass through modified TiO2Improve TiO2Absorption to visible light and by TiO2Photocatalysis
The upper recycling for realizing catalyst is most important above agent solid carrier.Textile fabric fabric can increase nanometer as support
Catalyst and pollutant contact area can be improved in the availability of photochemical catalyst, and textile fabric fabric has durability.This
Outside, the modification of nano-photocatalyst can increase absorption of the catalyst to dyestuff.
Researching and designing person solidifies TiO on cotton material2And Fe-C-TiO2Photochemical catalyst, with sodium metasilicate and nano-photocatalyst
Mixing is then coated on cotton fabric.Followed by phenol is carried out in the cotton material insertion flowing photo catalysis reactor of functionalization
It decomposes (Hazard.Mater.151 (2008) 62-64).This method has certain defect, and photochemical catalyst is mixed with adhesive
Afterwards, surface is covered with sodium silicate binder, it is poor to absorb light effect, and sodium metasilicate bonding force is not very easy to fall off in fabric surface by force
To reduce photocatalytic activity.
