Description
Technical field
The invention belongs to field of polymer composite material, are related to a kind of light-catalyzed reaction gel mould.
Background technique
In recent years, as China's economy develops rapidly, the sustainable growth of simultaneous population, a large amount of pollutants are discharged into
In the earth's surfaces aquatic ecosystem such as rivers and lakes, river basin ecological environment is caused to be destroyed, it is serious to restrict the sustainable of economic society
Development, influences people's lives quality.Sewage disposal technology and its engineer application, which have become, maintains social economy's sustainable development
The necessary component of exhibition.Various sewage treatment process based on physics, chemistry and biology principle continuously emerge, for toxicity
Greatly, the organic industrial sewage of difficult for biological degradation, based on the Photocatalyst of the principles of chemistry because having treatment effeciency high and consumption
Can be small the advantages that, the extensive concern of numerous researchers and engineers and technicians are caused.
Organic matter method in traditional photocatalytic degradation water is that catalyst granules is distributed in reaction system, sufficiently benefit
With the pollutant in the huge specific surface area catalytic decomposition sewage of nano particle, to achieve the purpose that purify sewage, but this is utilized
The photo catalysis reactor of kind suspension form, the time for reacting needs is long, and the nano particle in reaction system is difficult to be recovered,
The end processing sequences both expensive that catalyst is separated and recycled from sewage, in addition to this, the catalyst of dispersion and dissolution
Organic matter so that the penetrability of ultraviolet light is restricted, Low emissivity utilization rate caused by light scatters and effect of mass transmitting limit
The whole sewage treatment capacity of photo catalysis reactor has been made, catalyst is possible to be passivated or be washed out, therefore, this form
Photo catalysis reactor is difficult to widely be promoted and applied.Researcher, which begins one's study, loads the catalysis material of nanoscale
The inside of insertion substrate can make the liquid of catalyst direct contact flow, and can be effective without being dispersed in extexine in this way
The wash-off probability for reducing catalyst also can be improved using the substrate with high adsorption (amount) and be removed organic contamination from waste water
The efficiency of object avoids the last handling process for separating catalyst.Previous scholars have studied TiO2It is mixed into fixed carrier
In, such as glass, stainless steel, fiber, carbon nanotube and polymer, but these solid support methods suffer from various problem, such as
Catalyst is easily peeled off, poor compatibility and the flexibility difference of composite material etc..
Chinese patent CN101353186A discloses a kind of double rotating plate photoelectricity ponds liquid film reaction of environmental catalysis technical field
The method of device photo catalytically treating waste water, by TiO2It is solid together that photocatalyst is used as light anode and cathode in substrate
It is scheduled in shaft and organizes turntable in pairs, be partially immersed in waste water under double turntables, double turntables are used by the carbon brush being connected with shaft
Conducting wire is connected.It starts motor and controls the revolving speed of double turntables, so that the surface of double turntables forms one layer of liquid film.It is with ultraviolet lamp
Excitation light source, by TiO2The light induced electron of film turntable photoanode surface is transferred to rotating disk cathode surface, and light induced electron and cathode turn
The saturated dissolved oxygen reaction of panel surface generates H2O2, to the indirect oxidation and TiO of organic matter2The photoproduction of film light anode disc surfaces
Hole improves degradation efficiency to organic matter direct oxidation, and the rotation of turntable accelerates electrode surface and bulk solution substance
Exchange updates, but the catalyst TiO loaded2Obscission, and TiO are easy to happen when turntable quick rotation2It is certain to having for light
Inhibition, hamper its and further promote and apply.
Therefore, the catalyst for studying that one kind can reuse, high catalytic efficiency, less energy-consuming and load is not easily to fall off
Light-catalyzed reaction gel mould is of great significance.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of can reusing, high catalytic efficiency, less energy-consuming and
The catalyst of load light-catalyzed reaction gel mould not easily to fall off.
In order to achieve the above objectives, the technical solution adopted by the present invention are as follows:
A kind of light-catalyzed reaction gel mould includes light-catalyzed reaction site and polar group, the light-catalyzed reaction site
Peripheral region be strong absorption polar group region, the region other than polar group region is adsorbed in light-catalyzed reaction gel mould by force
For non-strong absorption polar group region；
The charge in the strong absorption polar group region and non-strong absorption polar group region is positive or is negative；
The current potential in the strong absorption polar group region is higher than the current potential in non-strong absorption polar group region；
The strong absorption polar group region is constituted or is gathered by weakly stable polar group by adsorbing polar group by force and constituted.
A kind of light-catalyzed reaction gel mould of the invention, non-strong absorption polar group region are absorption-storage area, can be inhaled
Attached and store the organic contamination molecule under a large amount of decentralized environments, strong polar group region of adsorbing is absorption-conversion zone, adsorbable
And be catalyzed organic contamination molecular degradation, when the organic contamination molecule on light-catalyzed reaction site after the reaction was completed, due to adsorbing by force
The current potential in polar group region is higher than the current potential in non-strong absorption polar group region, non-strong absorption polar group area on thin-film carrier
Domain absorption organic pollutant molecule under the action of concentration gradient and electrostatic attraction, can Spontaneous migration to by force adsorb polar group
On the light-catalyzed reaction site of region package, achievees the effect that continue reaction, greatly improve reaction efficiency.
As a preferred technical scheme:
