Description
Technical field
The present invention relates to oil smoke processing fields, particularly relate to Bi2WO6The compound-modified dynamic interception stainless steel of crystallite
The preparation method and application of silk.
Background technology
It is raw material, the silica of preparation that geo-polymer, which refers to natural minerals or solid waste or artificial silicoaluminate,
The three-dimensional network polymeric gel of tetrahedron and aluminum-oxygen tetrahedron composition.Geo-polymer belongs to alkali-activated carbonatite cementitious material, be by
Aluminum silicate raw material is prepared under the action of alkali-activator through processes such as mixing, molding, maintenances.It is generally acknowledged that ground
Matter polymer is mainly made of stratiform and chain silicate, and which part silicon is replaced by aluminium.In geo-polymer network, AI
Play network adjustment optimization, increases the link between long-chain.Since AI with Si valence states are different, it is therefore desirable to alkalinous metal
Atom（M）Maintain whole valence state balance.
Geopolymeric reaction is broadly divided into three steps：1. aluminosilicate dissolves under highly basic effect；2. aluminum-oxygen tetrahedron and silicon
Oxygen tetrahedron polycondensation, system gelation；3. gel structure is reformed, polymerization, system hardening.Research is thought to meet when aluminium silicate particles
When to alkali-activator, aluminium and silicon are dissolved out from particle, and rich aluminium glue body is generated into solution.Aluminium and silicon in colloid after a period of time
Concentration reaches saturation, and starting polymerization becomes oligomer, can be stabilized after oligomer is grown up to a certain size.With reaction
Progress these oligomer being stabilized be aggregated to formation three-dimensional polymer structure together, therefore generate intensity.
Compared with Portland cement, this novel cementitious material of geo-polymer has the following advantages：（1）Anti- folding
Intensity is high.Based on being connected with SiO with AlO covalent bonds due to geo-polymer, have with general mineral grain or discarded composition granule
Good interface affinity, therefore the flexural strength of this kind of material is higher.Compared with cement-based material, when compression strength is identical
When, geo-polymer has higher flexural strength, about 2-3 times of cement-based material.（2）High temperature resistant heat insulation effect is good.Ground
Matter polymer is not aoxidized between 1000-1200 DEG C, is not decomposed, and is stablized under the high temperature conditions.Linear shrinkage ratio under 400 °C
For 0.2%-2%, the linear shrinkage ratio at 800 DEG C is 0.2%-2%.60% or more can be still kept in 600 °C of lower geo-polymers
Green strength.The refractory ability of geo-polymer is better than traditional portland cement, thermal coefficient 0.24-0.38W/
（m·K）, it can compare favourably with light fire brick, good heat-insulation effect.（3）Acid-alkali-corrosive-resisting.Geo-polymer aquation does not generate calcium alum
The sulphoaluminate phases such as stone, thus it is resistant to sulfate attack.The stability of geo-polymer in an acidic solution is good：5%
In sulfuric acid solution, resolution ratio only has the 1/13 of portland cement；Its resolution ratio only has portland cement in 5% hydrochloric acid solution
1/12.（4）Green energy conservation is environmental-friendly.In manufacture of cement, calcination of cement clinker releases the CO of about 1t2.Geo-polymer
Production mainly using solid waste such as Coaseries kaolin, flyash, mineral wastes as raw material, need not be calcined in production process
Lime stone does not need high temperature firing.Therefore, compared with cement, the CO of production geology polymer2Discharge capacity is very low, about cement
The 20% of production.
The solid material of geology polymer material is very abundant, nearly all mineral and Industry Waste rich in silicon and aluminium
Slag is all likely to become the raw material of geo-polymer, in past 30 years people oneself through to multi mineral and industry byproduct into
Aluminosilicate mineral in research, such as a variety of natures of calcined kaolin, feldspar is gone, flyash, slag and waste incineration fly
The industrial residues such as ash all can be used as the raw material of geo-polymer.
Bi2WO6It is a kind of typical n-type semiconductor, energy gap is 2.75e V, it is by Bi2O2 2+Layer and WO4 2-
The perovskite lamellar structure that layer is alternately formed along c-axis, has in electrode material, solar energy conversion, catalyst etc. and widely answers
With.There is document report：Kudo and Hiji has found Bi2WO6Photochemical catalyst is to O2Development there is photocatalysis and Zou etc.
It was found that the organic compound that can degrade under visible light, as a kind of novel semi-conducting material, Bi2WO6Catalysis material is ground
A new approach will be opened up for photocatalysis removal and degradable organic pollutant by studying carefully, and be had in terms of the depollution of environment and new energy development
There is very important practical value.Due to Bi2WO6Itself there is special layer structure, narrow energy gap can be adequately sharp
With sunlight, so research Bi2WO6Catalysis material improves its utilization to sunlight, new to curbing environmental pollution and developing
Have great importance in terms of the energy.
It is well known that effective photocatalytic process needs to have following condition：The high migration of light induced electron and hole
Rate；Direct visible light catalytic effect；Suitable bandwidth；To the high absorption capacity of organic pollution.It is generally believed that light is urged
It is that receptor potential is lower than semiconductor conduction band potential to change the precondition that reaction occurs, higher than semiconductor valence band potential for bulk potential,
The migration of effective photo-generated charge carriers could be obtained in this way.
