Description
Technical field
The present invention relates to a kind of production method of the efficient photocatalyst of doped nano titanium dioxide, a kind of doped carbon is especially provided
The production method of atom Nano titanium dioxide photocatalyst.
Background technology
Industrialize and bring severe contamination to social environment：Since 20th century, global industry causes rapid economic development, people
Living standard improve constantly, urban modernization building is prominent to fly development, and industrial production is increased rapidly, and traffic is flourishing, to the mankind
Living environment causes severe contamination.The time that modern has 80% daily is spent indoors, even in closing or closed
Indoor life, the quality of indoor environmental quality directly affects the healthy of people.
And TiO2Because of its conversion and storage in solar energy, CO2Application in terms of reduction, complicated organic pollutant degradation
And its have good chemical stability, abrasion resistance, low cost, it is nontoxic the features such as and the light as most application potential
Catalyst.Particularly in recent years, becoming increasingly conspicuous with the energy in world wide and environmental problem, the research of photocatalysis technology is got over
To be more taken seriously.
But TiO2Only there is effect to accounting for ultraviolet light of the solar energy less than 5%, and to accounting for the visible ray of solar energy 43%
Do not act on, so making TiO2Photoresponse scope expands to visible region as the emphasis studied at present from ultraviolet region.For
Make TiO2Photocatalyst produces effective absorption in visible region, and we are entered by the carbon atom that adulterated to Nano titanium dioxide microwave
Row is modified.
The content of the invention
The present invention provides a kind of photocatalyst production method for the indoor air purification that can be effectively absorbed in visible region generation.
The particular content of the present invention is to carry out carburizing to titanium dioxide first；Then a kind of air cleaning catalyst spray is prepared, is pressed
Percentage by weight meter is consisting of the following：The weight ratio adulterated shared by carbon atom Nano titanium dioxide is 0.1~10%, dispersant
Shared weight ratio is 0.1~5%, and the weight ratio shared by bonding agent is 0.1~5%, and remaining is aqueous solvent.
Further, described Nano titanium dioxide particle diameter be less than 25 nanometers, its crystal formation be Detitanium-ore-type, rutile-type,
It is mixed crystal type, armorphous；
Further, described doping nitrogen-atoms Nano titanium dioxide is that titanium dioxide is oozed by microwave mode
Carbon：Microwave power is 500W~5000W, and the time of microwave operational is 2 minutes~60 minutes；
Further, described dispersant is selected from alkylamine salt, sulfuric ester salt, phosphates, quaternary ammonium salt, benzene sulphur
One or more mixtures in Barbiturates, polyoxyethylene, polyalcohols；
Further, described bonding agent in polytetrafluoroethylene (PTFE), carboxymethyl cellulose, sodium metasilicate, polyvinyl alcohol one
Plant or several mixing.
The present invention can be quick, efficient, lasting purification air, thoroughly eliminate formaldehyde, benzene,toluene,xylene, ammonia,
The pernicious gases such as TVOC simultaneously can suppress to kill bacterium；The technological process of production of the present invention is simple, production cost is low, the nontoxic nothing of product
Taste, safety and environmental protection.
