Abstract
The photocatalytic superhydrophilic composite titanium dioxide and tin dioxide film may be used to the outer surface of glass, ceramic and metal. It is prepared through sol-gel process. The composite sol containing tin dioxide in 0.1-20 mol% is distributed onto the substrate via soaking and pulling process or painting process and the substrate with the composite sol is first baked and dried under infrared light and then heat treated at 300-680 deg.c inside a furnace to obtain the composite film. The composite titanium dioxide and tin dioxide film of the present invention has high photocatalytic activity and high superhydrophilic characteristic to degrade harmful matter, self clean and eliminate fog under the irradiation of natural light and sunlight.
Description
Technical field:
The present invention relates to a kind of titanium dioxide and tin ash composite photocatalyst super-hydrophilic thin film, be used for the outer surface of glass, pottery, metal.
Background technology:
Because TiO
2That film itself has is nontoxic, pollution-free, can decomposing organic pollutant and pernicious gas, sterilization, anti-these excellent functions of water smoke, environmental pollution serious day by day have very wide application prospect now.At present, known TiO
2The photocatalysis efficiency of film is lower, and super water-wet behavior needs UV-irradiation and just can obtain embodying, and has so just limited the popularity that this film is used.In order to overcome above-mentioned deficiency, need to improve TiO
2The photocatalysis efficiency of film and super water-wet behavior.
Summary of the invention:
The present invention is in order to overcome existing TiO
2The deficiency of film aspect photocatalysis efficiency and super water-wet behavior, and a kind of titanium dioxide and tin ash (TiO are provided
2/ SnO
2) the composite photocatalyst super-hydrophilic thin film.
The technical solution adopted for the present invention to solve the technical problems is: make earlier TiO respectively
2Colloidal sol and SnO
2Colloidal sol, SnO in the colloidal sol
2Molar content be 0.1%～20%, adopt dip-coating method or rubbing method that the complex sol that makes is evenly distributed on the substrate then, and the substrate that will scribble complex sol toasts dryly under infrared light, put into again and obtain after stove is heat-treated.
The present invention has under natural daylight or solar irradiation, can improve TiO
2/ SnO
2The photocatalytic activity of laminated film and super water-wet behavior, the advantages such as harmful substance, self-cleaning decontamination and anti-water smoke of more effectively degrading.
The specific embodiment:
The present invention adopts known sol-gel process to make.For TiO
2/ SnO
2The preparation of complex sol both can have been adopted two one-step hydrolysis methods, promptly made earlier TiO respectively
2Colloidal sol and SnO
2Colloidal sol is again with SnO
2And TiO
2Colloidal sol is pressed SnO
2Molar content is that 0.1%～20% ratio mixes; Also can directly titanium alkoxide and butter of tin be pressed the SnO that generates
2Molar content is that 0.1%～20% ratio is dissolved in the organic solvent and fully and stirs, and drips a certain amount of water again and is hydrolyzed, and obtains TiO after fully stirring a period of time
2/ SnO
2Complex sol.Adopt dip-coating method or rubbing method that the complex sol that makes is evenly distributed on the substrate, and the substrate that will scribble complex sol toast drying under infrared light, put into stove heat treatment under 300 ℃～680 ℃ temperature again, just can obtain having than pure TiO
2The TiO of the super water-wet behavior that the photocatalytic activity that film is high is become reconciled
2/ SnO
2Laminated film.
