Technical field
The present invention relates to the preparation method of bismuth tungstate/attapulgite composite material, belong to nonmetallic mineral material finishing
Technical field.
Background technology
In recent years, problem of environmental pollution is increasingly serious, and energy scarcity problem is also extremely urgent.Facing above-mentioned two big crises
Situation under, people expand pollution control, the scientific research of environmental protection.Using semiconductor as catalyst, sunshine is utilized
Catalyzing oxidizing degrading polluter is as a kind of effective pollution administration method, the heat studied as environmental protection science
Point.Under research background as above, various countries research worker have developed a variety of semiconductor nano materials, such as TiO2、ZnO、α-
Fe2O3Deng the improvement for pollutant.With TiO2Exemplified by, although nano-TiO2With very high stability, stronger photocatalysis
Ability, the prominent advantage such as nontoxic pollution-free.But, because titanium dioxide energy gap is 3.2 ev, therefore meaning that TiO2
The incident photon that matching wavelength is less than 387 nm can only be absorbed, light absorbs are only limitted to ultraviolet region, the luminous energy of this wave band
Amount accounts for the 5% of the sunshine for being irradiated to ground.The ratio of visible light part accounts for the 45% of solar energy, and is actually reached earth's surface
Solar radiation energy concentrates on 460~500nm wave-length coverages.Therefore how light-catalyzed reaction efficiently is carried out using natural light,
Exploitation just can increasingly aroused people's interest by the photochemical catalyst of excited by visible light.
In recent years, having focused on for research is found the two-phase gold with different crystal morphology by more research workers
Belong on oxide, by expanding light abstraction width to visible region, to develop novel photocatalyst.Nearest many researchs hair
It is existing, bismuth tungstate (Bi2WO6) it is layer structure, with the characteristic such as dielectric, luminous, catalysis, have well in many association areas
Application prospect.Its unique crystal and electronic structure, shows higher photocatalytic activity, particularly to visible light-responded bright
It is aobvious.In addition, bismuth based semiconductor catalysis material also has the unique advantage to hardly degraded organic substance high catalytic activity.Utilize absorption
The nanoclay of excellent performance carrys out the weight that immobilized semiconductor catalyst is the current dispersiveness and reusing for solving catalyst
Method is wanted, active component is combined with the clay-phase of bigger serface turns into an important development direction of catalytic field.It is recessed
Convex rod native (ATP) is a kind of inexpensive natural minerals, microcosmic upper with one-dimensional layer chain nano pore structure, hydrone and one
Determining the organic molecule of size can directly adsorb in its duct, macroscopically show as big specific surface area and stronger absorption
And ion-exchange performance, attapulgite can be used as a kind of excellent catalyst carrier material.In recent years on recessed soil with partly leading
The report of the material of bluk recombination is more, but is also not seen reported at present on bismuth tungstate and the compound document of recessed soil.
The content of the invention
The purpose of the present invention is:A kind of preparation method of bismuth tungstate/attapulgite composite material is provided, the preparation method institute
The Bi obtained2WO6/ ATP composite Load Balanceds, good dispersion, raw material is easy to get, reproducible without complicated equipment, to combustion
Expect that the thiophenic sulfur in oil product has very high photocatalytic degradation effect.
The present invention technical solution be:A certain amount of bismuth nitrate, sodium tungstate and attapulgite are taken, deionization is added to
Stirred in water;It is then transferred into reactor, hydro-thermal reaction, and is incubated;Reaction product is washed and alcohol is washed, drying grinding, obtains tungsten
Sour bismuth/attapulgite composite material Bi2WO6/ATP。
Wherein, the mol ratio of bismuth nitrate and sodium tungstate is 1:3~1:Between 7, quality of the attapulgite relative to bismuth tungstate
Than for 1:3~1:8.
Wherein, hydrothermal temperature is 180~240 DEG C, and the hydro-thermal reaction time is 16~24h.
Wherein, 60~100 DEG C of 12~24h of insulation after hydro-thermal reaction.
It is an advantage of the invention that:
1st, employ a kind of more easy chemical technology and prepare load more uniform, bismuth tungstate/bumps of good dispersion
Rod stone composite material, without complicated equipment, chemical raw material used is cheap, and favorable repeatability has very high commercial introduction
Value.
2nd, attapulgite itself has abundant microcellular structure and larger specific surface area, has very well to organic matter macromolecular
Adsorption capacity in situ;Attapulgite solid-carried catalyst powder, it is to avoid catalyst powder separation is difficult, the problems such as reclaim difficult.
3rd, the composite prepared by the present invention can catalytic degradation organic pollution, fully profit under the conditions of solar irradiation
With solar energy, this kind of composite has very big potential using value in terms of deep desulfurization of gasoline.
4th, strict control mixing time in bismuth tungstate/bumps rod composite material, course of reaction is prepared using the step of hydro-thermal method one
And temperature, it is to avoid cause the generation of accessory substance because of the difference of mixing time and temperature, it is ensured that the photocatalysis of influence material is lived
Property.
5th, on the one hand catalyst is made to be contacted rapidly, fully with organic matter using the excellent adsorption capacity of attapulgite;It is another
Contain in the recessed soil of aspect after a small amount of calcium, magnesium, iron plasma, Material cladding, the foreign ion in recessed soil enters the lattice of bismuth tungstate
In, cause the defect of lattice to increase, promote the transfer of light induced electron, it is to avoid light induced electron itself it is compound, by carrier with
Concerted catalysis effect between active component, and then largely strengthen the catalytic activity of composite.
6th, with attapulgite, sodium tungstate, bismuth nitrate is primary raw material, is synthesized using hydro-thermal method, concavo-convex by optimizing
The technological parameters such as rod soil and mass ratio, hydrothermal temperature and the hydro-thermal time of bismuth nitrate and sodium tungstate control bismuth tungstate/concave convex rod
The pattern and distribution of composite, so as to obtain the product of Load Balanced, good dispersion.
