Abstract
The present invention relates to a kind of mixed solution preparation method promoting photocatalyst to purify air, have absorption carrier carried noble metal (such as Pt, Au etc.) mix with titania solution, by heating in vacuum ball milling, make noble metal be deposited on titanium dioxide surface in a large number, obtain the titania solution of carried noble metal.After noble metal contacts with titanium dioxide, the fair of fermi level makes electronics from titanium dioxide to metal flow, thus realizes the separation of electron hole by changing system electronic distribution.
Description
Technical field
The present invention relates to a kind of mixed solution preparation method promoting photocatalyst to purify air.
Background technology
Along with the development of society needs with commercial production, air pollution in recent years becomes the most serious, at present process the commonly used photocatalyst technology of air pollution, photocatalyst has played huge contribution in air purification field, but for polluting the most serious environment, as: new car, the new home etc., photocatalyst clean-up effect seems the rapidest, by the present invention so that photocatalyst product plays under rugged environment significantly has a pain, substantially increase the purification speed of photocatalyst product, adapt to the demand of Modern air heavily polluted area.
Summary of the invention
The purpose of the present invention is contemplated to solve the problem in background technology, it is provided that a kind of mixed solution preparation method promoting photocatalyst to purify air.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that a kind of mixed solution preparation method promoting photocatalyst to purify air, comprises the steps:
1)
The Maifanitum powder of 1500 mesh-2500 mesh is heated up to 120 degrees Celsius-600 degrees Celsius；
2)
Titania solution is injected in silicone acrylic emulsion, and puts in the vacuum equipment that pressure is 0.3pa-0.8pa stand-by；
3)
The Maifanitum powder of step (1) gained was thoroughly mixed with the ratio of 1:0.4 ~ 1 with the solution of step (2) gained in 5 ~ 60 seconds, and obtained loading the nano medical stone solution of photocatalyst substance after being cooled to room temperature；
4)
The ultraviolet finishing agent ball milling that Pt Yu Au3-30% mixed solution adds 2% is obtained 1000-3000 mesh precious metal solution；
5)
At normal temperatures, the metal ultraviolet finisher solution of the nano medical stone solution of step (3) gained, step (4) gained is inserted pressure mix 1 hour-1.5 hours more than stirring in the de-airing mixer of 0.8pa, be promoted photocatalyst and purify the mixed solution of air.
The present invention, compared with background technology, has and is mixed with titania solution by absorption carrier carried noble metal (such as Pt, Au etc.), by heating in vacuum ball milling, makes noble metal be deposited on titanium dioxide surface in a large number, obtains the titania solution of carried noble metal.After noble metal contacts with titanium dioxide, the fair of fermi level makes electronics from titanium dioxide to metal flow, thus realizes the separation of electron hole by changing system electronic distribution.Noble metal decorated it is demonstrated by the large increase to photocatalytic activity；After the photocatalytic activity of titanium dioxide is improved, clean-up effect becomes rapider；For polluting the most serious environment, as: new car, the new home etc., photocatalyst clean-up effect seems the rapidest, by the present invention so that photocatalyst product plays under rugged environment significantly has a pain, substantially increase the purification speed of photocatalyst product, adapt to the demand of Modern air heavily polluted area.It can remove the function of more than the 300 kind of pollutants in airs such as formaldehyde, benzene, toluene, ammonia, chloroform efficiently.
