Abstract
The invention discloses a method for preparing a silver/cadmium sulfide/titanium dioxide composite photocatalytic material. According to the method, TBOT and Cd(NO3)2.4H2O are taken as raw materials to prepare CdO/TiO2 with the evaporation-induced self-assembly (EISA) method firstly, then CdO/TiO2 and Na2S.9H2O are taken as the raw materials to prepare CdS/TiO2, and finally CdS/TiO2 and AgNO3 are taken as raw materials to prepare the silver/cadmium sulfide/titanium dioxide ternary composite photocatalytic material with the photodeposition method. The composite material is an inorganic photocatalytic material, is stable in performance, quite high in photocatalytic activity and resistant to chemical corrosion and photocorrosion, and has important significance in photolysis of water, sterilization, preparation of solar sensitization batteries, environment protection and other fields.
Description
Technical field
The present invention relates to a kind of preparation method of silver/cadmium sulfide/titanic oxide composite photochemical catalyst material, belong to optic catalytic composite material preparation field.
Background technology
TiO
2be the catalyst of heterogeneous catalytic reaction, valence-band level is comparatively dark, has nontoxic, corrosion resistance, high stability, reaction condition is gentle, to organic matter degradation non-selectivity in water pollutant, mineralising thoroughly, non-secondary pollution, the advantage such as cheap is the generally acknowledged photochemical catalyst most with practical application foreground.Disposing of sewage, improving drinking water quality, controlling atmosphere pollution, purify the air of a room, catalyzing hydrolysis hydrogen manufacturing, sterilization and prepare the aspects such as solar energy sensitized cells and be all widely used.Particularly in environmental protection, TiO
2wide application prospect is presented especially as photochemical catalyst.
But the photosensitized reaction of TiO2 is confined to ultraviolet region, this occupies 5% of solar spectrum, in addition, due to the right height recombination rate again of light induced electron and hole, thus limits photocatalytic activity and the application prospect of TiO2.Therefore, expand absorption region and promote that being separated of photo-generated carrier is the two large effective measures strengthening TiO2 photocatalytic activity.So scientific worker begins one's study doping vario-property to construct hetero-junctions to improve the photocatalytic activity of TiO2 both at home and abroad, why welcome structure hetero-junctions is is because it can not only improve the performance of single material, and can introduce the property that homogenous material do not have.But be confined to synthesize binary composite, trielement composite material just started to be studied by people in recent years.
Summary of the invention
The object of this invention is to provide a kind of preparation method of silver/cadmium sulfide/titanic oxide composite photochemical catalyst material, attempt a kind of synthetic method of trielement composite material, in titanium dioxide, add cadmium sulfide simultaneously, silver, CdS energy gap is less, its band-gap energy is 2.5eV, with band-gap energy 3.2eVTiO2 compound, when excitation energy is not enough to the TiO2 in exciting light catalyst, but CdS can be excited, because TiO2 conduction band is higher than CdS, the electronics produced that makes CdS is stimulated more easily moves on TiO2 conduction band, the hole of generation is excited still to stay CdS valence band, this electronics is conducive to the separation of electric charge to the migration of TiO2 from CdS.When penetrating with the illumination of enough excitation energies, there is electron transition in CdS and TiO2 simultaneously, due to energy level difference, electron-collection is at the conduction band (CB) of TiO2, and void coalescence is in the valence band (VB) of CdS, light induced electron and hole can freely carry out with adsorption matter exchanging the separation of charge effect that CdS/TiO2 improves system.Ag in addition
+doping change TiO2 surface cleanliness and add blemish.Be entrained in the Ag on TiO2
+, accept electronics under light illumination and be reduced to simple substance Ag.Metal A g constitutes a large amount of micro cells on TiO2 surface, the electronics that illumination excites rear TiO2 surface to produce moves to the anode (Ag) of micro cell, anode (TiO2) surface is then stayed in hole, thus also achieves electronics and is separated with the effective of hole.Therefore this composite has excellent photocatalysis performance, prepares the catalysis material that combination property is superior.
