Description
Technical field:
The present invention relates to organic in the purposes containing Mo, Ce, Al oxide nanofiber, more particularly to processing room air
In pollutant technical field, it can also be used to handle organic pollutants.
Technical background:
Room air can discharge the pollution sources of harmful substance due to indoor introducing, bring harmful substance in air, indoors
Accumulation, can not remove causes people to occur a series of malaise symptoms for a long time.And the time of city dweller about 80% is life
Therefore room air pollution and the healthy of people have close relationship indoors.In recent years, building is used due to a large amount of
Ornament materials, furniture and modernization household electrical appliances and office equipment, cause serious room air pollution, increasingly threaten the body of people
Body health, also gradually causes the extensive attention of people, country also puts into effect policy and environmental legislation strictly to control room air dirty
Dye.
Room air pollution mainly includes gaseous chemical pollutant such as CO, ammonia, sulfur dioxide, nitrogen oxides and formaldehyde.
These gaseous contaminants are colourless, incidental stimulus smell, and mainly human health is impacted by respiration.Particularly
Long-time Formaldehyde Exposed, SO2、NOxChronic respiratory disease can be caused, cause dizziness, weak, sensory disturbance and immunity are low
Inferior symptom, and then cause respiratory disorder, hepatogenotoxicity lesion etc..Teratogenesis and mutagenic effect can occur for this kind of gaseous contaminant
Should, add people and suffer from Hodgkin lymphoma, the probability of myelomatosis etc..
The measure of current indoor air pollutants preventing and treating includes photocatalyst method, ozone sterilization method, high-tension electricity anion method, charcoal
Material Physics absorption method.But because the indoor air pollutants duration is long, concentration is low, domestic existing indoor pollutant is administered
Technology is simultaneously immature, while existing, the lower cost of operation is high, efficiency is low, eliminate the problem of not exclusively causing secondary pollution, therefore anxious
A kind of price to be developed is low, efficiency high does not produce the processing method of secondary pollution.
Currently for the pollution of formaldehyde, the research of light Touch technologies is relatively more, that is, utilizes TiO2Photochemical catalyst is in ultraviolet lighting
Lower oxidation of formaldehyde molecule is penetrated to CO2And H2O, make its mineralising for harmless inorganic substances (bibliography R.Portela,
I.Jansson,S. Suárez,M.Villarroel,B.Sánchez,P.Avila Chem.Eng.J.310(2017)560-
570).But photocatalyst technology needs to use ultraviolet light to excite TiO2The degraded to organic matter could be completed, therefore its is effective
Using being subject to certain restrictions.O is catalyzed compared with light degradation organic pollution2The high-level oxidation technology of oxidizing organic substrates by
Attention (bibliography J.J.Pei, J.S.Zhang, the Critical review of catalytic of people
oxidization and chemisorption methods for indoor formaldehyde removal J.Hvac&
R.Res.17 (2011) 476-503), it is advantageous that different ultraviolet lights are in the presence of a catalyst, O2Or air is will have
Degradable machine thing is CO2And H2Substantially reduced on O, running cost, while using not limited by environment and condition.Utilize this
HCHO is degraded to CO by item technology2And H2O be one very green process (bibliography B, Bai, Q.Qiao, J.Li,
J.Hao,Chin.J.Catal.37(2016)102-122).And the key of technique is the selection of catalyst, at present research compared with
Many be metal oxide surface supported noble metals such as Pt, Au etc. (bibliography N.D.Wasalathanthria,
T.M.SantaMariaa,D.A.Kriza,S.L.Dissanayakea,C.H. Kuo,S.Biswasa,S.L.Suiba,

2762, Z.H.Xu, J.G.Yua, M.Jaroniecb, Appl.Catal.B:Environ.163 (2015) 306-312), it is this kind of
Catalyst activity is high, but noble metal price and inactivation during the course of the reaction are the factors for limiting its application, therefore selection non-noble
Metal oxidation catalyst is a direction.
Metal oxide MoO3It is the high oxidation of a class with strong oxidation-reduction quality and reversible electron transfer capacity
Type catalyst and noble metal composite catalyst carrier (bibliography Y.Shen, R.Huang, Y.Y.Cao, P.P.Wang,
