Abstract
The invention relates to a preparation method of an up-conversion luminescent material based on triplet-triplet annihilation and application of the material to a light-catalyzed reaction. The up-conversion luminescent material comprises a triplet photosensitizer, an energy receptor and a high-molecular polymer, wherein the molar ratio of the triplet photosensitizer to the energy receptor is 1 to (50-1) to 250. The triplet photosensitizer can be used for achieving strong absorption of visible spectrum, and visible light is converted into ultraviolet light by virtue of a triplet-triplet annihilation process, so that the utilization rate of sunlight is effectively increased and the light degradation efficiency of organic matters in water is improved.
Description
Technical field
The invention belongs to photochemical catalysis water-treatment technology field, be specifically related to preparation and the application in photochemical catalysis water treatment field thereof of the up-conversion luminescent material of a class based on T-T annihilation.
Background technology
Along with developing rapidly of industry, a large amount of waste water that contain organic pollutant enter nature, and the mankind's living environment is gone from bad to worse.Various pending Wastewater Dyes waste water accounts for significant proportion, and waste water from dyestuff colourity is dark, toxicity is large, and concentration is large, stable chemical nature, and being difficult to, with traditional chemical method and biological process degraded, becomes one of environmental pollutant urgently to be resolved hurrily.
At present, conventionally utilize semiconductor material (as: TiO
2, WO
3, C
3n
4) as photosensitizers dye wastewater treatment using.The advantages such as this type of semiconductor material has stable chemical nature, cheap and easy to get, nontoxic can produce hydroxyl radical free radical and the hole with strong oxidation capacity under UV-irradiation, and organic pollutant is completely oxidized to CO the most at last
2, H
2o and other SO
4 2-, NO
3 -, Cl
-deng mineral ion.Therefore, can carry out advanced treatment to the organic pollutant in waste water.As utility model patent CN201962161U Multi-selection photocatalytic dynamic controllable sewage treatment device, the preparation method of patent of invention CN101011660A high activity codoping titanium oxide catalyst and application method thereof, the preparation method of patent of invention CN101011754A activated carbon fibre loading titanium oxide thin film and application method thereof are all to use TiO
2as photocatalyst.
But there is certain defect in this type of photosensitizers: greater band gap, only can absorb UV-light, and to visible ray and infrared light, without response, sunlight utilization ratio is only 3-5%; Seriously restricted the effect of this type of semiconductor material in photochemical catalysis water treatment field.The solution that appears as this difficult problem of upper switch technology has brought hope.
The method that realizes upper conversion at present is mainly used three kinds: the one, and two-photon technology; The 2nd, in the frequency of rare earth ion, change; The 3rd, based on triplet state-triplet state-bury in oblivion upper conversion of (TTA, triplet-triplet--annihilation).On these three kinds, in switch technology, the above two need higher exciting light energy (10
6wcm
-2), far away higher than the quantity of radiant energy (100mWcm on sunlight earth's surface
-2, on ground, sun power standard adopts AM1.5G).
The required exciting light energy of the upper conversion of TTA is not high, and the general solar energy than showing radiation can meet; Triplet state photosensitizers and energy acceptor can select space large, and upper efficiency of conversion is high.Therefore, the upper conversion of TTA has huge applications value aspect photocatalytic degradation water pollutant.
TTA is upper to be changed detailed process and arrives its singlet excited after into triplet state sensitiser absorption photon, then through the arrival triplet excited state that jumps of leaping up between system, the photosensitizers of triplet excited state can by TTET process by transmission ofenergy the triplet state to acceptor, after acceptor density in triplet excited state acquires a certain degree, the acceptor of two triplet excited states collides the acceptor that produces a singlet excited mutually, another acceptor is got back to ground state, now in the acceptor of singlet excited, launches fluorescence and gets back to ground state.Here require the triplet energy level of triplet state photosensitizers higher than the triplet energy level of acceptor, and the first singlet excited of acceptor is lower than the first singlet excited of sensitizing agent, the wavelength ratio of the up-conversion fluorescence therefore obtaining excites light wavelength short.
Inventor's discovery, TTA up-conversion does not also have successful Application sewage disposal at present, especially uses the semiconductor material (TiO of ultraviolet excitation
2, C
3n
4etc.) as photosensitizers degraded water pollutant.
For this reason, the inventor, through studying for a long period of time, successfully adopts multiple upper conversion dyestuff to solve visible ray as photosensitizers and utilizes a difficult problem, and immobilized in high molecular polymer by up-conversion, by convex lens principle, effectively strengthens upper conversion light intensity.By the organic content in degradation of sewage that successfully constructs of upper transfer equipment.
