Technical field
The present invention relates to photocatalysis field, and in particular to a kind of titanium dioxide optical catalyst of adsorbable organic matter and preparation
Method.
Background technology
China industrial source VOCs (volatile organic matter) discharge capacity is about 1335.6 ten thousand tons, the wherein production of VOCs within 2010
Link discharge VOCs is about 263.0 ten thousand tons, and oil product and solvent storage and carrier have discharged 129.5 ten thousand tons of VOCs pollutants,
Technical process with VOCs as raw material discharges two 176.9 ten thousand tons, using containing VOCs products and discharges link and then discharges
766.63 ten thousand tons.Prediction the year two thousand twenty China VOCs discharge capacitys are up to 1785.31 ten thousand tons.At present, to the place of volatile organic matter
Reason method includes combustion method, catalytic oxidation, absorption process, absorption method.
Content, processing cost, treatment effeciency with reference to volatile organic matter etc. consider, at present, catalytic oxidation, suction
Attached method is common method；And catalytic oxidation typically selects optically catalytic TiO 2 method, catalysis material swashs in photon energy
Give, electronics transits to conduction band positions from valence band, conduction band formed light induced electron, valence band formed photohole, using electronics-
The oxidation in hole pair and reducing property, make oxygen and hydrone be excited into superoxide radical and hydroxyl radical free radical etc. with Strong oxdiative
The free radical of power, degraded environment in organic pollution, optically catalytic TiO 2 stable chemical nature and its there is automatically cleaning work(
Can, therefore, turn into current most promising environmentally friendly mode currently with titanium dioxide treatment organic pollution；But, it is traditional
Titanium dioxide optical catalyst is made up of metal oxides such as titanium dioxide, and catalyst is unfavorable for Adsorption of Organic amount very little
Had an effect with organic matter.
The content of the invention
The technical problems to be solved by the invention are current, using conventional gas processing method treatment organic pollution
Treatment effeciency is low, it is therefore intended that provide the titanium dioxide optical catalyst and preparation method of a kind of adsorbable organic matter, solves to remove
The low problem of organic pollution efficiency in gas.
The present invention is achieved through the following technical solutions：
A kind of titanium dioxide optical catalyst of adsorbable organic matter, preparing material includes organic matter sorbing material, titanium dioxide
Titanium colloidal sol, high-molecular resin solution, light-guide material, foaming agent.
In processing gas during volatile organic contaminant, catalytic oxidation is to separate with absorption method, catalysis oxidation side
Traditional titanium dioxide optical catalyst is made up of metal oxides such as titanium dioxide in method, to Adsorption of Organic amount very little not
Had an effect beneficial to catalyst and organic matter；And in adsorption method, can only be by changing sorbing material after sorbing material saturation
Absorption can just be ensured, and the sorbing material after saturation can form new pollution sources；The present invention can largely inhale adsorption method
Advantage with organic pollutants combines with the advantage of a large amount of degradation of organic substances of titanium dioxide optical catalyst energy, has invented one kind
Can largely adsorb and while be capable of the titanium dioxide optical catalyst of a large amount of degradable organic pollutant, solve titanium-dioxide photo and urge
Agent is small to the adsorbance of organic pollutants and problem that organic pollution removal efficiency that bring is low, and solves absorption simultaneously
The simple absorbing and storing organic pollution of material and the low problem of the degradation efficiency of organic pollution that brings；The present invention is a kind of new
The catalysis material of type, it is of the invention to prepare the works that organic matter sorbing material in material realizes a large amount of absorption organic pollutions
With solving the problems, such as that traditional titanium dioxide optical catalyst adsorbance is small；Titanium dioxide is that one kind is partly led in TiO 2 sol
Body, the electronics in making molecular orbit under the photon excitation with certain energy leaves valence band (Valence band) and transits to
Conduction band (conduction band).So as to form photohole [Hole+] in material valence band, light induced electron is formed in conduction band
[e-], because titanium dioxide granule is very big in body phase titanium dioxide, light induced electron starts to be lived to particle surface in arrival conduction band
Be easy in dynamic process it is compound with photohole, so as to from macroscopically we cannot observe the effect of photon excitation.But
The titanium dioxide granule of nanometer, so electronics is easier to be diffused into plane of crystal, is caused originally not charged due to small-sized
2 different pieces of plane of crystal occur in that opposite polarity 2 microcell-light induced electrons and photohole.Due to photoproduction electricity
Son and photohole have very strong energy, are much higher by the intensity of the strand of general organic pollution, it is possible to easily
Organic pollution is resolved into the state of most original；High-molecular resin solution, resin is main film forming matter, macromolecule resin
Solution is easy to the processing and forming in later stage, and adds the resin of foaming agent, bubble can be evenly distributed with resin matrix, finally
The product of formation can form small cells, can also contain in the titanium dioxide optical catalyst of a kind of adsorbable organic matter of meeting aftershaping
There are equally distributed small cells, increase the specific surface area of the titanium dioxide optical catalyst of adsorbable organic matter, so as to increase by two
The adsorption capacity of titania photocatalyst；Foaming agent is added in high-molecular resin solution so that；The resin of loose structure can be right
Organic matter carries out selection absorption；Light-guide material, is the material for referring to electromagnetic radiation to be converted into electric current, and electromagnetic radiation is often referred to
Ultraviolet light, visible ray and infrared light.Generally after this kind of material static electrification, by just can be by electrostatic after the light irradiation of special wavelength
Change into electric current.
In sum, compared with existing conventional gas processing method (catalytic oxidation, absorption method), the present invention can be obvious
Improve the treatment effeciency of organic pollution in dusty gas in ground.
The organic matter sorbing material is NACF or graphene oxide or carbon fiber.The present invention preferably can be with transparent
Graphene oxide solution, graphene oxide is a kind of new carbon of excellent performance, with specific surface area and table higher
The abundant functional group in face；NACF is then threadiness, and micropore is covered with fiber, and it compares particle to organic gas adsorption capacity
Activated carbon is high several times to tens times in atmosphere.
The light-guide material is optical fiber.Optical fiber is a kind of fiber being made up of glass or plastics, can be used as light
Conduction instrument.
The high-molecular resin solution is epoxy resin solution or acrylic resin soln.Epoxy resin has very strong interior
Poly- power, molecular structure is fine and close, so its mechanical property is higher than universal thermosetting resins such as phenolic resin and unsaturated polyester (UP)s,
Contain active great epoxy radicals, hydroxyl and ehter bond, amine key, ester bond isopolarity group in epoxy resin solidifying system, assign
Epoxy curing compound is to metal, ceramics, glass, concrete, timber isopolarity base material with excellent adhesive force；Acrylic resin film
Excellent performance, fast light, weatherability is good, heat-resisting, and resistance to paint baking over, chemical-resistant and the performance such as corrosion-resistant are all fabulous.
The material for preparing also includes foam stabiliser.Foam stabiliser makes stomata fine and closely woven uniform, when system is in low sticking
When spending the stage, it makes hole wall stabilization, and stomata can grow into the thickness for being suitable for perforate.
A kind of preparation method of the titanium dioxide optical catalyst of adsorbable organic matter, comprises the following steps：
