3Ω), be difficult to accurate measurement.Silver (Ag) mixes or the titanium dioxide of compound Ag is to improve TiO
2An effective way of material light catalysis property and electroconductibility.But because the Ag ion is easily at TiO
2Separate out in the colloidal sol and precipitate, cause the titanium dioxide research work of mixing silver or compound silver to rest on the lower state of silver content (the atomic percent At% of Ag＜2) always.So, if can prepare the titania powder of high silver content (At%＞2) or film mixes for research silver or the photocatalysis performance or the conductivity of the titanium dioxide of compound silver all have important meaning.
Summary of the invention
The purpose of this invention is to provide a kind of method for preparing the silver/titanium dioxide laminated film of high silver content.
The method of the silver/titanium dioxide laminated film of preparation high silver content of the present invention, step is as follows:
1) with the compound dissolution of titanium in organic solvent, the compound of titanium and the mol ratio of organic solvent are 1: 4～15, mixture is put into ice-water bath stirs, A liquid;
2) water, complexing agent, organic solvent and Silver Nitrate powder 1: 0.1 in molar ratio～1: 6～18: 0.2～1.5 are mixed and constantly stirring, all dissolve, get B liquid up to Silver Nitrate;
3) B liquid is dropwise splashed in the A liquid that always is placed on ice-water bath, continue then to stir, up to the colloidal sol that obtains colour stable, again that colloidal sol is stand-by in-10～20 ℃ of following ageings;
4) carrier impregnation after will cleaning lifts in above-mentioned colloidal sol, and pull rate is controlled at 1～10cm/min, has whenever lifted one deck, in 450～600 ℃ of following thermal treatment 5～60min, obtains Ag/TiO
2Film.
The compound of above-mentioned titanium can be butyl (tetra) titanate, titanium chloride or isopropyl titanate.Said organic solvent can be ethanol, ethylene glycol monomethyl ether, propylene glycol monomethyl ether, ethylene glycol phenyl ether, Benzenediol methyl ether or propyl alcohol.Complexing agent can adopt diethanolamine, citric acid, hydroxylated cellulose (HPC) or polyoxyethylene glycol (PEG).Said carrier can be simple glass sheet, quartz glass plate or ceramic plate.
Be coated in the Ag/TiO on the carrier
2The thickness of film can be controlled by speed that lifts and number of times.
Beneficial effect of the present invention is:
The present invention adopts the sol-gel dip-coating method to prepare Ag/TiO
2Film, method and use equipment are simple; Prepared Ag/TiO
2In the film, the content height of Ag: the At% of Ag can reach 10.36.The high Ag/TiO of this Ag content
2Film has the TiO than low Ag content (At%＜2)
2Film and do not contain the TiO of Ag
2Better photocatalysis performance of film and electroconductibility.
