Description
Technical field
The invention belongs to photocatalyst field, especially a kind of efficient-decomposition formaldehyde goes out the photocatalyst of germ smelly eliminating.
Background technology
Photocatalyst is the catalyst using energy as the energy, as plant passes through the chlorophyll progress photosynthesis in greenery.Leaf
Green element is chemically reacted as catalyst under the action of the sun, by carbon dioxide and water, generates oxygen and starch.Ye Lv
Element itself, is no any variation afterwards before the reaction.Not changed before and after reaction is generated is exactly catalyst.
It is using having a little for photocatalyst very much, such as can only be reacted originally in the case of up to tens thousand of degree, it can be
It plays a role under room temperature.In our daily lifes, make anything and nearly all be unable to do without catalyst.As utilization A substances and B
Substance is by chemical change, it is necessary to the substantial amounts of energy when making C substances.The energy mentioned herein, have heat, electric power,
Light etc..The mankind constantly produce in daily life such as synthetic resin or synthetic fibers, medicine, pesticide, fuel, detergent,
The various substances such as coating, sticker, and these technologies be unable to do without catalyst.
Three most widely used fields of catalyst are：Synthetic resin field, energy field, the skies such as waste discharge gas disposal of automobile
Gas field of purification.
1956, capital of a country Gong Yun fibers university added rattan true professor Zeng Wei Fuji hero teaching inventive photocatalyst, and leads to
It crosses and is manufactured hydrogen oxide and obtain patent of invention, decompose the spot on white shirt.
Photochemical catalyst can be applied to the purposes such as the depollution of environment, antifouling, anti-covered with clouds, sterilization, the hydrogen manufacture of more water decomposition
" material of optical-electronic energy conversion device " is also concerned.Wherein, in terms of photochemical catalyst and manufacture cost, titanium oxide should
With widest.
Common titanium oxide only irradiates according to ultraviolet light and is used as photochemical catalyst.However sunlight, just visible ray is main
, the ultraviolet light that sunlight is included only has all about 5% or so at most.For this purpose, solar irradiation is mapped to high efficiency function
Function, be required in the visualization of light-catalysed visual catalyst.In addition, the illumination in light and tunnel indoors, does not play light
Catalyst, this purposes, it is seen that photochemical is indispensable.
In recent years, nitrogenous titanium oxide has been absorbed into visual optical arena, and also showing light according to the irradiation of visible light urges
The function of agent.Using the titanium oxide of nitrogen, by high-temperature heating treatment in nitrogen and ammonia gas, it is synthesized.But due to this height
The reason that temperature heats, the oxidation titanizing for the Rutile structure for causing the becoming more meticulous of titanium oxide, activity low are urged to reduce light
The reason for agent is active.
Anti-oxidant titanium catalyst is to be directed to the corresponding important substances such as environmental problem and energy problem, particularly high performance
The exploitation of photochemical catalyst is the field that whole world scale gets most of the attention.This achievement in research is the visible light portion using sunlight
Divide and utilize, develop the new synthetic method of the acidifying titanium photochemical catalyst of efficient smooth function type.This achievement in research, the sun
Carry out higher in the depollution of environment of light and energy conversion efficiency, usual sunlight is less than such visible ray in indoor and tunnel
In terms of being only only not exposed to environment, the effect of antifouling, anti-covered with clouds, sterilization etc. is expected.In addition, it is not necessary that the extensive life of special device
The expansion of production is also easy, and social effect is very big.
The content of the invention
Against the above deficiency, the present invention is intended to provide a kind of efficient-decomposition formaldehyde goes out germ smelly eliminating photocatalyst, which touches
Matchmaker can high efficiency environment purification and germ of going out, smelly eliminating.
