Description
Technical field
A kind of normal-temperature efficient removes the formula and its preparation technology of the catalysis material of VOCs pollutants, is related to multifunctional nano
Composite modified carbon based material, belongs to constant temperature catalyzing and technical field of air purification.
Background technology
The time that modern times have more than 80%~90% for each person is spent indoors, and the quality of IAQ directly affects
Health and work, learning efficiency.It is indoor with the raising of building seal and widely using for New Building Materials
VOCs has turned into one of indoor important air pollutants.Be easy to cause during VOCs excessive concentrations in room air it is acute in
The symptoms such as headache, dizziness, cough, nausea occur in poison, the lighter；Hepatotoxicity occurs or even goes into a coma quickly, and some may be used also in severe one
It can be in peril of one's life.Hang up one's hat in the interior of VOCs pollutions, slow poisoning can be caused, infringement liver and nervous system, caused
General weakness, drowsiness, pruitus etc..The pregnant woman lived in VOCs pollution environment, causes the probability of fetal anomaly much high
In ordinary person, and it is possible to which the intelligence development of child from now on is impacted.
At present, the mode for reducing or preventing indoor VOCs pollution has：1）Material of the selection without VOCs is fitted up, from root
Prevent pollution sources on this, this is best and simplest method, but in daily life VOCs source of releases diversity, it is more difficult to it is real
Now prevent completely；2）Material surface is sprayed among air or is applied to using the material of Strong oxdiative ability, and oxidation VOCs promotes it
Decompose, but product can still cause damage to human body after Strong oxdiative material itself and oxidation；3）In release VOCs material surface spray
Closure material is applied, forms the confining bed of densification, preventing VOCs release reduces content in its air, and this method can be reduced effectively
Concentration in VOCs rooms, but can not fundamentally remove VOCs in material and pollute；4）The sorbing materials such as purification of air charcoal bag are put, can
Effectively absorption indoor VOCs, but due to passive adsorption and VOCs rate of release is very fast, indoor VOCs concentration declines limited；5）Using
Air cleaning facility, wind circulation rate is lifted, effectively can quickly remove indoor VOCs pollution.
The material for core that air cleaning facility uses determines that it removes VOCs performances height, and existing market is more using porous
Material, such as molecular sieve, clay, carbonized resin and activated carbon realize the Adsorption to VOCs in air.Wherein activated carbon is inhaled
Attached is conventional VOCs sorbing materials, is had the advantages that quick, safe, economical but indoor low for removing with absorbent charcoal material
Concentration VOCs still deposits obvious deficiency：1）For presently commercially available activated carbon based on coal-based carbon, specific surface area is in 1100 m more2/g
Hereinafter, under VOCs adsorption rate and capacity are relatively low；2）Because indoor VOCs concentration is relatively low, and composition is various, unmodified
Absorbent charcoal material, it is weak to low concentration VOCs absorption, just reach adsorption equilibrium more than national standard safe level；3）Absorbent charcoal material
The simple physical adsorption way of type genus is removed to VOCs, when VOCs amounts are larger in air, easily reaches adsorption saturation, is used
Cycle is relatively short, and the activated carbon after saturation is easily into pollution source.
Therefore, many researchers have done more work both ways：First, modification is carried out to activated carbon, at soda acid
Reason, metal ion and modified oxide etc., specific surface area can be further lifted, improve surface characteristic, to lift activated carbon pair
VOCs compatibilities, so as to lift adsorption capacity and selectivity；Second, the VOCs pollutants for being directed to benzene, toluene etc develop light and urged
It is agent, such as titania addition, immobilized.But have efficient absorption concurrently and catalysis developing material still is apparent not enough：1）With urging
Change the activated carbon of function except VOCs materials are more based on noble metal, such as Pt, Ag, Pd, cost is higher, from marketing application also
Have very over long distances；2）Titania meterial doping preparation technology is complicated, immobilized technique（Loaded on contenting carbon material）Obtain oxidation titanium
Material is more to be prepared from titanium precursors, such as butyl titanate, titanium tetrachloride, it is high to there is technological process length, discharging of waste liquid, sintering temperature
The shortcomings of；3）Titanium oxide itself specific surface area is relatively low, excessively slow to VOCs enrichment rates, and speed is removed so as to influence VOCs；4）Oxygen
Change titanium and its support materials excite and still relatively use ultraviolet light, irradiation risk is easily brought in actual application and is attached caused
Ozone endangers.
