The invention discloses a kind of preparation method and applications of Bi base catalyst, this method comprises the following steps: polyphosphoric acids (1) being dissolved in the mixed liquor of water or ethyl alcohol or water and ethyl alcohol, poly phosphoric acid solution is made, in ice-water bath, Bi salt is added, stirring dissolves Bi salt；(2) inorganic acid solution is added in the lysate of step (1), is stirred evenly；(3) mixed liquor of step (2) is stood, precipitating, by washing, drying and grinds to obtain BiPO4, or the mixed liquor of step (2) is transferred in reaction kettle, it seals, carries out hydro-thermal process, wash, dry and grind up to BiPO4.Being completely dissolved for bismuth nitrate is realized using polyphosphoric acids ice-water bath, and no hydrolysis phenomena occurs, the BiPO being prepared4It, can a variety of different types of dyestuffs of high efficiency photocatalysis degradation and mixed dye pollutant with different pattern and crystal phase.
Description
Technical field
The present invention relates to micro Nano material preparation, in particular to a kind of preparation method and application of Bi base catalyst.
Background technique
Global industry metaplasia produces and also brings serious environmental pollution while rapid development.Especially water environment pollution is asked
The living environment that threaten the mankind increasingly severely is inscribed, society and economic progress are restrict.Therefore, it water pollution control and controls
Reason becomes the hot issue that the whole world is paid close attention to jointly.Printing and dyeing industry is one of the world's largest pollution sources and water resources consumption person.
There are about the waste water from dyestuff of 1.6 billion cubic meters to discharge into natural water every year in China according to investigations, causes the serious pollution of water body.But mesh
The method of preceding water process is big, highly concentrated pollutant mostly for discharge amount, having of being difficult to convert low for concentration in water body
There are no very effective methods for the purification of machine pollutant, and Photocatalyst developed in recent years is this problem
Solution provide preferable approach.
BiPO4It is a kind of important Bi based nano-material, it is not only stable, safe and non-toxic, and also being proved to be one kind can
With photocatalysis degradation organic contaminant, fluorescence radiation, catalysis organic synthesis, sensor and can be used for radioactive element (uranium, americium,
Plutonium, neptunium etc.) measurement and nuclear waste disposal multifunctional material.Currently, synthesis BiPO4Method be mainly liquid phase method: hydro-thermal
Method, solvent-thermal method, microwave method, ultrasonic method etc..The source Bi used is mostly Bi (NO3)3.However, Bi salt is extremely easy hydrolysis, cause
BiPO4Synthesis process be difficult to, the BiPO of preparation4Microstructure appearance is single.Existing literature is disclosed using organic solvent come molten
Bismuth nitrate is solved, but on the one hand organic solvent increases production cost, on the other hand serious pollution environment, instrument and equipment and damage
Operator's health.Also there is document to disclose using nitric acid the acid-base property for adjusting reaction solution simultaneously, but bismuth nitrate cannot
It is completely dissolved, and the phosphorus source used is single, such as sodium phosphate (Na3PO4) and phosphoric acid (H3PO4) etc., phosphate radical therein
(PO4 3-) directly with bismuth ion (Bi3+) reaction generation bismuth phosphate (BiPO4), reaction is simple, bismuth phosphate pattern is single.
Summary of the invention
Goal of the invention: it is an object of the present invention to provide a kind of preparation methods of Bi base catalyst, utilize polyphosphoric acids ice-water bath
Realize being completely dissolved for bismuth nitrate, no hydrolysis phenomena occurs, the BiPO being prepared4With different pattern and crystal phase.
It is a further object of the present invention to provide a kind of application of Bi base catalyst, which can high efficiency photocatalysis drop
Solve a variety of different types of dyestuffs and mixed dye pollutant.
Technical solution: the present invention provides a kind of preparation method of Bi base catalyst, includes the following steps:
(1) polyphosphoric acids is dissolved in the mixed liquor of water or ethyl alcohol or water and ethyl alcohol, poly phosphoric acid solution is made, in ice-water bath
In, Bi salt is added, stirring dissolves Bi salt；
(2) inorganic acid solution is added in the lysate of step (1), is stirred evenly；
(3) mixed liquor of step (2) is stood, precipitating, by washing, drying and grinds to obtain BiPO4, or by step (2)
Mixed liquor be transferred in reaction kettle, seal, carry out hydro-thermal process, wash, dry and grind up to BiPO4。
Further, the Bi salt of the step (1) is bismuth nitrate.
Further, step (2) inorganic acid is phosphoric acid, sulfuric acid, nitric acid or hydrochloric acid.
Further, the concentration of step (2) inorganic acid solution is 1.2~9mol/L.
Further, the concentration of step (1) poly phosphoric acid solution is 0.06~1g/mL.
Further, the quality that bismuth nitrate is added in the step (1) is less than the quality of polyphosphoric acids.
Bismuth phosphate BiPO4Synthesis be substantially and use bismuth nitrate as bismuth source, however bismuth source, especially bismuth nitrate easily water
Solution cannot be dissolved in water and form uniform solution, further affect bismuth ion and participate in reaction, cause BiPO4Synthesis process it is difficult
With regulation, the BiPO of preparation4Microstructure appearance is single.Polyphosphoric acids, can be under water environment due to its unique paradigmatic structure
Bismuth nitrate is completely dissolved to form uniform clear solution, provides condition for subsequent correlated response.Then pass through control reaction
Acid environment (sulfuric acid, nitric acid, hydrochloric acid etc. the is added) crystal phase of Lai Shixian bismuth phosphate of liquid and the regulation of pattern.
The structural formula of polyphosphoric acids is as follows:
The Bi base catalyst is applied to the degradation of organic pollutant in environment water.Pass through the organic mould of photocatalytic degradation
Quasi- pollutant has investigated the photocatalysis performance of bismuth phosphate prepared by the present invention, finds it not only and can effectively degrade and is a variety of not of the same race
