Background technology

Titanium dioxide, as Chinese white, has been widely used in the industries such as toothpaste, cosmetics, coating.Usually under normal temperature and pressure conditions, its chemistry, physical property are highly stable, are insoluble to alkali, acid, water and common organic solvents, even with the extremely strong gas of the chemical reactivities such as hydrogen fluoride, nitrogen and hydrogen sulfide, do not react.As photochemical catalyst spray plant after film forming there is durability, attrition resistance, safety, economy and the advantage such as practical.

Titanium dioxide has rutile (rutile, R type), anatase (anatase, A type) and three kinds of crystalline textures of brockite (brookite).Wherein, rutile is the most stable crystalline solid, and anatase and brockite at high temperature can convert rutile structure to, and this reaction is irreversible.

When titanium dioxide is subject to energy and is greater than the irradiation that titanium dioxide can be with, can produce electronics and electric hole, they and water and oxygen react and can produce reactive hydrogen oxygen radical (OH) and peroxy isoreactivity oxygen (O ₂) composition.These active oxygen compositions have very strong reactivity, reactive hydrogen oxygen radical particularly, it has the energy of 120kal/mol, and the covalent bond of the carbon-carbon (C-C) of formation organic compound, carbon-nitrogen (C-N), carbon-hydrogen (C-H), oxygen-hydrogen (O-H), nitrogen-hydrogen (N-H), in conjunction with bond energy 100kal/mol left and right; If reactive hydrogen oxygen radical and peroxy etc. act on the associative key of carbon-carbon, carbon-nitrogen, carbon-hydrogen, oxygen-hydrogen, nitrogen-hydrogen.These are destroyed easily in conjunction with meeting, and the organifying thing decomposes.So utilize photocatalysis technology almost can make all harmful organic compounds finally be decomposed into the avirulent materials such as carbon dioxide and water.

The titanium dioxide that the photochemical catalyst that we adopt usually is anatase, under ultraviolet ray irradiation and visible light condition, can make it that light-catalyzed reaction occurs.Titanium dioxide has the divinity that decomposes whole organic compounds.
