Abstract
The present invention relates to a kind of preparation method of halloysite nanotubes/nanometer titanium dioxide composite material.Its technical scheme is：The alcohols dispersant of the galapectite after the galapectite of 15 ~ 60 parts of quality or heat treatment, the deionized water of 100 parts of quality, the surfactant of 0 ~ 2 part of quality and 0 ~ 20 part of quality is uniform, acid is added to 3≤pH value ＜ 7 or adds alkali to 7 ＜ pH value≤10, slurry is obtained.According to the mass ratio of Er Yangization Tai ︰ galapectites for (1 ~ 5) ︰ 10, to titaniferous material is added in slurry, are uniformly dispersed, then the mixed material after dispersion is loaded into reactor, and 6 ~ 24h is reacted under the conditions of 100 ~ 220 DEG C；Washing, dries, and halloysite nanotubes/nanometer titanium dioxide composite material is obtained.The present invention has the characteristics of process is simple, relatively low, environment-friendly production cost and easy large-scale production, and the halloysite nanotubes/nanometer titanium dioxide composite material specific surface area prepared with the method is big, absorption property is good, photocatalysis efficiency is high.
Description
Technical field
The invention belongs to galapectite nano composite material technical field.Specifically related to a kind of halloysite nanotubes/nanometer two
The preparation method of titanium oxide composite material.
Background technology
Galapectite is a kind of natural nano clay mineral with nano tubular structure, perfect crystalline and Large ratio surface, with
Kaolinite belongs to polymorphic form, aboundresources, low production cost and cleanliness without any pollution.Due to its special nano tubular structure, compared with
Big specific surface area so that halloysite nanotubes have adsorptivity higher, the organic pollution that can be used in adsorptive liquid（Such as
Dyestuff, agricultural chemicals etc.）, microorganism, heavy metal ion etc., it can also be used to composite activeness and quietness, surface be modified and efficient catalytic
Carrier of agent etc..
Titanium dioxide has ultraviolet catalytic activity higher, is widely used in organic pollution（Such as decis, organophosphor
Agricultural chemicals, phenol, methyl alcohol etc.）And the catalytic oxidation-reduction degraded of some inorganic matters, so as to play a part of to purify sewage.By
Doping vario-property, can be expanded to visible light wave range by excitation source wavelength, greatly improve catalytic efficiency.
Halloysite nanotubes/nanometer titanium dioxide composite material, the both excellent absorption property with halloysite nanotubes
And dispersive property, water pollutant can be adsorbed, while there is the photocatalysis performance of nano titanium oxide, the pollution that will can be adsorbed
Thing is degraded, therefore, halloysite nanotubes/nanometer titanium dioxide composite material is at a kind of ideal water pollutant purification
Reason material.
At present, preparing the method for halloysite nanotubes/titanium dioxide has sol-gel process, solvent-thermal method etc..Colloidal sol-solidifying
Glue method is that butyl titanate is obtained into precursor sol in galapectite suspension reclaimed water solution, by centrifugation, dry, roasting, grinding, system
Obtain the nano titanium oxide of halloysite nanotubes load（Elegant cloud is passed, the spring heat treatment of Lu elder generation is sub- to titanium dioxide/galapectite degraded
The influence of methyl blue characteristic, Chinese powder industry, 2008, (4):31-34.）, the product that butyl titanate is hydrolyzed to form at room temperature
It is amorphous state, by being changed into anatase after the heat treatment under the conditions of uniform temperature, calcining heat is improved, and can promote anatase
Generation and crystal grain growth, but the structure of galapectite can be destroyed.Solvent-thermal method is that butyl titanate is dissolved in into isopropanol to be obtained two
Titania precursor liquid solution, adds galapectite, watery hydrochloric acid regulation pH value, and it is anti-in 160 DEG C to carry out solvent heat in autoclave
24h is answered, washing, the dry content of titanium dioxide that obtains are the titanium dioxide/halloysite nanotubes catalyst of 31.8wt%（Wang essences
The research of titanium dioxide and BiOBr modified composite photocatalysis degradation organic contaminants, Institutes Of Technology Of Zhejiang, 2013.）.The party
Titanium dioxide obtained in method is Detitanium-ore-type, particle diameter about 5 ~ 15nm, because the method uses organic matter as solvent, cost compared with
There is certain security risk under height, high temperature and high pressure environment, waste reaction solution has to environment and necessarily pollutes, it is necessary to process.
The content of the invention
It is contemplated that overcoming prior art defect, it is therefore an objective to provide a kind of process is simple, low production cost, environment-friendly
With the preparation method of the halloysite nanotubes/nanometer titanium dioxide composite material of easy large-scale production, with the method prepare angstrom
The specific surface area of Lip river stone nanotube/nanometer titanium dioxide composite material is big, adsorption efficiency is high and photocatalysis efficiency is high.
To achieve the above object, the technical solution adopted by the present invention is：
By the galapectite after the galapectite of 15 ~ 60 parts of quality or heat treatment, the deionized water of 100 parts of quality, 0 ~ 2 part of quality table
Face activating agent and 0 ~ 20 part of alcohols dispersant of quality, are uniformly dispersed, and add acid to 3≤pH value ＜ 7 or add alkali to 7
＜ pH value≤10, are obtained slurry.
According to the mass ratio of Er Yangization Tai ︰ galapectites for (1 ~ 5) ︰ 10, to titaniferous material is added in the slurry, dispersion is equal
It is even, obtain mixed material；The mixed material is loaded into reactor again, 6 ~ 24h is reacted under the conditions of 100 ~ 220 DEG C；Then use
Deionized water is washed, and is dried, and halloysite nanotubes/nanometer titanium dioxide composite material is obtained.
