Description

Application of the fullerene-MOF composites in volatile organic matter is removed
Technical field
The invention belongs to fulvene compounding material application field, and in particular to fullerene-MOF composites are removing volatilization Application in property organic matter.
Background technology
Volatile organic matter refers to boiling point at 50-250 DEG C, and saturated vapour pressure is more than 133.32Pa at room temperature, at normal temperatures It is present in the type organic in air in vapour form.The presence of which enduringly endangers the health of the mankind and the ring of surrounding Border.They may reside in the places such as air, soil, laboratory, factory and are finally touched by us.Agricultural, the energy, grain Production, manufacturing industry and routine use solvent etc. can produce volatile organic matter.Many volatile organic matters are carcinogenic substances Matter, they can be made one with various cancers such as lymph cancer, hematopoiesis cancers.They can to the lung of people, liver, immune system, Nervous system produces serious harm；Also it can make one to influence the life of the mankind with serious chronic disease.Volatility is organic Thing can also be such that their long-term or slow poisonings are further damaged to human body indirectly by influence animals and plants.Moreover, They can also influence weather, threaten ozone layer to destroy the living environment of the mankind.Therefore, volatility is efficiently removed organic Thing (VOC) has great importance for environmental protection and health.
In order to reduce the harm of volatile organic matter as far as possible, many effective means are developed.Wherein, adsorb It is used to remove the volatile organic matter in environment as a kind of efficiently complete technology.Porous material such as zeolite, activated carbon Volatile organic matter can be effectively adsorbed Deng with huge specific surface area and pore volume.Metal organic framework compound (MOFs) as a kind of new porous material, they have bigger specific surface area and pore volume in absorption volatility to have There is very big advantage and potential application in machine object space face.Metal organic framework compound be passed through by metal ion and part it is very strong Formation of chemical bond three-dimensional order porous network.Since finding, they are just because in sides such as gas storage, catalysis, sensings Face has potential application and received significant attention.Huge specific surface area, pore volume due to possessing, metal organic framework chemical combination Thing can also adsorb substantial amounts of volatile organic matter.However, even if metal organic framework compound possesses huge pore volume, they For adsorbing or limited for volatile organic matter：Volatile organic matter molecular dimension is less than metal organic framework compound Hole size, they can only be adsorbed onto the surface in hole after entering metal organic framework compound (MOF) inside, it is impossible to exist in large quantities Can not have in remaining space after MOF cavitys, i.e. metal organic framework compound absorption volatile organic matter to volatility Machine thing is further adsorbed.Therefore, more efficiently using metal organic framework compound loose structure and lift its adsorptivity It can be extremely important.
The content of the invention
An object of the present invention is to provide application of the fullerene-MOF composites in volatile organic matter is removed.
Fullerene-MOF the composites are made up of metal organic framework compound and fullerene.
Fullerene-MOF the composites are prepared by the method comprising the following steps：By the organic bone of metal Frame compound is soaked in fullerene solution so that fullerene is distributed in MOF duct, obtains fullerene-MOF composites.
The metal organic framework compound is organic point at least containing a Ge Duo flute profiles functional group with organic carboxyl acid etc. Son is as part, and metal ion is used as the metal organic framework compound material with 3-D ordered multiporous structure being centrally formed Material；Wherein, metal ion can be rare earth metal and the transition metal ions such as Zn, Mn, Mg, In, Zr；Metal-organic framework materials Concretely：MOF-180, MIL-53, MOF-177, MOF-200, NU-1000 and Uio-68 etc..
The hole size of the metal organic framework compound is 0.7~10nm, and its duct can accommodate what is had found Most of fullerene.MOF pore sizes can be determined by specific surface area measuring instrument and mono-crystalline structures parsing is obtained.
The fullerene solution is described to have can dissolve the organic solvent of fullerene as solvent using fullerene as solute Machine solvent includes toluene, ortho-xylene, o-dichlorohenzene etc..
The concentration of the fullerene solution can be 10-7Mol/L to 10-2Between mol/L.
The fullerene is following at least one：C60、C70、C76、C78、C84、C86, C88, C90Deng empty fullerene.
The soak time is 1-7 days.In immersion process, the color of metal organic framework compound is gradually deepened.
The mass fraction of fullerene is 0.5%~10% in the fullerene-MOF composites, concretely 1%- 5%.
It is a further object of the present invention to provide the side that a kind of utilization fullerene-MOF composites remove volatile organic matter Method.
The method that utilization fullerene-MOF composites provided by the present invention remove volatile organic matter, including following steps Suddenly：
Fullerene-MOF composites are first subjected to degassing process, is subsequently placed in the atmosphere containing volatile organic matter and adsorbs Organic matter, you can.
The temperature of the degassing is as high as possible but not higher than 200 DEG C, and degassing time requirement is more than 8 hours.
The volatile organic matter be boiling point at 50-250 DEG C, at room temperature saturated vapour pressure exceed 133.32Pa it is organic Thing, including acetone, n-hexane, benzene,toluene,xylene, carbon disulfide etc..
The partial pressure range of the volatile organic matter in an atmosphere is in 0.001%-80%.
Can be by determining the adsorption/desorption curve of fullerene-MOF composites, adsorbing front and rear weight change and volatility The change in concentration of organic matter judges adsorbance.
Methods described may also include fullerene-MOF is multiple before fullerene-MOF composites are de-gassed into processing Condensation material is dried in vacuo, and obtains the operation of dry fullerene-MOF composites.
The vacuum drying temperature can be 80 DEG C -200 DEG C；The vacuum drying time is more than 8 hours, to ensure solvent Thoroughly removed.
The present invention chooses variety classes fullerene and the compound of dissimilar metals organic framework compounds formation is carried out Volatile organic matter is adsorbed.As a result show, C60Addition substantially increase metal organic framework compound absorption toluene vapor Adsorbance, is that pure MOF, to 1.5-8 times of organic matter adsorbance, illustrates C under equal conditions60It is scattered in answering of being obtained in MOF-177 Condensation material can more efficiently adsorption of organic vapors.
In the fullerene-MOF composites that the present invention is obtained, the mass fraction of fullerene can by control fullerene with The proportioning of metal organic framework compound is adjusted.It can reach that optimal adsorption volatility is organic by adjusting their ratio The effect of thing.
Fullerene-MOF the composites that the present invention is obtained can be used for the removing of indoor volatile organic compounds, such as paint, Solvent and gas that finishing, furniture etc. are distributed.Chemical plant and laboratory often use substantial amounts of organic solvent, and they can be produced greatly The organic steam of amount, not only endangers party, also pollutes the environment and other people are damaged indirectly, therefore, fullerene-MOF Composite can be used for the removing of chemical plant and laboratory organic steam.The fullerene-MOF composites can be widely applied to room Screen pack of interior adsorbent, air purifier and air-conditioning etc..
