Abstract
The invention discloses a kind of chlorine bismuth vanadate photocatalyst, preparation method and applications.Chlorine bismuth vanadate photocatalyst chemical expression is Bi9V2O18Cl.The present invention uses high temperature solid-state method or wet chemistry method, and the chlorine bismuth vanadate photocatalyst for preparing is that one kind contains Bi3+The inorganic material of bismuth ion, prepares convenient and swift, realizes and light-catalysed reaction is produced under the irradiation of visible ray, and light-catalysed efficiency is higher, the physics and stable chemical nature of photochemical catalyst.Organic dyestuff, organic hazardous solvent that the chlorine pucherite that the present invention is provided can be used in degrading waste water；Also can be as fabric finishing agent, as preparation antibacterial, deodorization functions textile.
Description
Technical field
The present invention relates to a kind of catalysis material, preparation method and application, it is a kind of inorganic material, more particularly to a kind of
For the photochemical catalyst chlorine pucherite Bi of degradable organic pollutant9V2O18Cl and preparation method thereof.
Background technology
With developing rapidly for industry, people enjoy while science and technology brings convenience to life and also result in living environment
Deteriorate, particularly with closely bound up water pollution of living.Present water pollution already leads to the dead and biology of a large amount of marine organisms
Kind falls sharply；Domestic water aspect is also subject to considerable influence simultaneously.In order to meet the eager needs of sustainable development, urgently
Problem of environmental pollution need to be solved.In many environmental pollutions, most common is water pollution, is also to work and live anxious with people
The problem that cut is closed.Therefore, it is the emphasis of environmental protection effectively to curb environmental pollution.At present, widely used solution environmental pollution
Method have：Chemical oxidization method, physisorphtion, high temperature incineration method and microorganism treatment.These processing methods can not be by
Pollutant is thoroughly innoxious, and it is also possible to brings the problem of secondary pollution.How green, it is efficient solve water pollution into
It is the problem of current urgent need to resolve.
Inorganic photocatalyst applications in the major progress that the treatment of environmental pollution is in recent years, wherein with titanium dioxide TiO2
Headed by conductor photocatalysis material turn into research focus.But, because these material energy gaps are big, it is necessary to absorb ultraviolet
Light could realize photocatalysis, and the problem so brought is low application efficiency.So, it is devoted to widening titanium dioxide both at home and abroad always
Absorption spectrum.Current researcher is by a series of modified of catalysis material, such as adulterating, compound means widen visible ray
Response, or find other emerging catalysis materials.It is that photocatalysis field one is difficult to find new high efficiency photocatalyst
Huge and long-term task is photocatalytic applications in contaminant degradation, the core in photolysis water hydrogen field.
The content of the invention
The deficiency that the present invention exists for existing catalysis material, there is provided a kind of preparation method is simple, to organic pollution
Photocatalytic Activity for Degradation function admirable chlorine bismuth vanadate photocatalyst, preparation method and applications.
To achieve the above object of the invention, the technical solution adopted by the present invention is to provide a kind of chlorine bismuth vanadate photocatalyst, it
Chemical general formula be Bi9V2O18Cl。
Technical solution of the present invention includes preparing two methods of chlorine bismuth vanadate photocatalyst as described above, and one kind is using solid
Phase method for calcinating, comprises the following steps：
（1）By chemical formula Bi9V2O18The metering ratio of Cl, weighs containing Bi respectively3+、V5+And Cl-Compound, fully ground in mortar
Mill, is well mixed, and obtains mixture；
（2）Mixture is calcined in air atmosphere, calcining heat is 300~600 DEG C, calcination time is 3~9 hours, natural
Crude product is obtained after cooling；
（3）By crude product grinding, well mixed, the calcining in air atmosphere, calcining heat is 600~900 DEG C, and calcination time is
6~8 hours；A kind of chlorine pucherite catalysis material is obtained after natural cooling.
In solid phase calcination preparation method, step（2）Described calcining heat is 300~500 DEG C, and calcination time is 3~6 small
When；Step（3）Described calcining heat is 500~850 DEG C, and calcination time is 6~8 hours.
Another preparation method of chlorine bismuth vanadate photocatalyst of the present invention is to use wet chemical method, including following step
Suddenly：
（1）By chemical formula Bi9V2O18Cl meterings ratio, weighs containing Bi respectively3+、V5+And Cl-Compound；Bi will be contained3+And V5+Change
Compound is dissolved in deionized water or salpeter solution respectively, then by mol, adds 1~3 times of total cation of complexing agent oxalic acid
Or citric acid, obtain containing Bi3+And V5+ Compound solution；
（2）Cl will be contained-Compound be dissolved in nitric acid, diluted with deionized water, then add step（1）Obtain containing Bi3+And V5 + Compound solution, obtain transparent mixed liquor；
（3）By step（2）The transparent mixed solution for obtaining is stirred at room temperature 3~8 hours, then in the bar that temperature is 37~80 DEG C
3~6 hours are stood under part；
（4）By step（3）The mixed liquor for obtaining dried process 10~20 hours under conditions of temperature is for 100~120 DEG C, obtain
Fluffy presoma；
（5）The presoma that will be obtained grinds to form powder, calcines 2~8 hours in air atmosphere, and calcining heat is 500~850
DEG C, room temperature is cooled to, obtain chlorine bismuth vanadate photocatalyst.
