Abstract
The present invention discloses a kind of preparation method of the silver-colored photochemical catalyst of zinc sulphide compound phosphoric acid.In turn include the following steps:Zinc acetate and thioacetamide and cetyl trimethylammonium bromide are added in deionized water, stirring is to being completely dissolved, obtain mixed solution, mixed solution is transferred to water heating kettle and is placed in 105~140 DEG C of heated at constant temperature in baking oven, question response takes out water heating kettle after terminating, and naturally cools to and supernatant is discarded after room temperature, collects sediment, washing, freeze-day with constant temperature, obtain zinc sulfide powder;Silver nitrate solution and disodium phosphate soln are mixed, yellow green colloid substance is formed, phosphoric acid silver colloid is generated;Obtained zinc sulphate powder is added in phosphoric acid silver colloid, stirring, precipitation separation, washing, drying produce a kind of silver-colored photochemical catalyst of zinc sulphide compound phosphoric acid.Silver orthophosphate is effectively distributed without assembling, and in the smaller particle of vulcanization zinc surface formation, improve catalytic activity.It can make zinc sulphide that there is visible light catalytic effect.
Description
Technical field
The present invention relates to a kind of preparation method for being used to handle the support type silver phosphate photocatalyst of organic wastewater, belong to and urge
Change field of material preparation.
Background technology
In the industrial wastewaters such as sanitary sewage, food processing and papermaking, contain carbohydrate, protein, grease, wooden
The organic substances such as element.These materials, can be by the biological chemistry action of microorganism to suspend or dissolved state is present in sewage
And decompose.Need to consume oxygen in its decomposable process, thus be referred to as oxygen consumption pollutant.This pollutant can cause molten in water
Solve oxygen to reduce, the growth of influence fish and other aquatiles.After oxygen in water exhausts, organic matter carries out anaerobic digestion, production
The bad smells such as raw hydrogen sulfide, ammonia and mercaptan, make water quality deterioration.
With the development of production, the murder by poisoning organic pollution produced in industrial and agricultural production seriously threatens environment and people
The health of class, seeks a kind of new and effective environmental improvement technology and has great importance.Photocatalysis technology is because of its energy-conservation, height
Effect, contaminant degradation are thorough, non-secondary pollution advantage, turn into a kind of emerging environmental improvement with important application prospect at present
Technology.In recent years, the development of new and effective visible-light photocatalyst turns into an important research content in photocatalysis technology.
In June, 2010, material research institution researcher has found that silver orthophosphate has the effect of photochemical catalyst, and photooxidation effect is
It is more than the decades of times for being currently known various photochemical catalysts.Because its unique Surface Physical Chemistry property and efficient visible ray light are urged
Change one of performance, focus as research.
But nanoparticles are easily reunited, surface area is greatly reduced after reunion, decreased effectiveness.Need to use appropriate carrier
Or change catalyst macrostructure to obtain preferable catalytic effect.
The content of the invention
The purpose of the present invention be for overcome in the prior art particulate matter be easy to reunion and cause effect difference etc. not enough there is provided one kind
The preparation method of support type silver phosphate photocatalyst.
The technical solution adopted by the present invention is in turn include the following steps:
1) in 10~30cm2It is molten that clean Quartz glass surfaces dip in the styrene ethanol that concentration is 2~6mol/L with brush
Liquid brush places 10~12h, then one layer of brush in atmosphere in quartz glass both side surface after drying naturally, then after drying naturally
Place 10~12h in atmosphere, then one layer of brush, 4~5 layers of brush altogether per side obtain a layers of polymer in quartz glass both side surface
Styrene;
2) quartz glass is placed in Muffle furnace, under nitrogen protection, is progressively warming up to 400~550 DEG C, and keep being somebody's turn to do
1~2h of temperature, is made the quartz glass of carbon-coating covering;
3) 20~24mmol silver nitrates are weighed, 20mmol/L silver nitrate solution is configured to, 6.6~8mmol phosphoric acid is weighed
Disodium hydrogen, is configured to 20mmol/L disodium phosphate soln;
4) both the above solution is mixed under 350~400 revs/min of rotating speed, forms yellow green colloid substance, continued
3~4h is stirred, disodium hydrogen phosphate and nitric acid silver reaction in whipping process generate phosphoric acid silver colloid;
5) phosphoric acid silver colloid brush is dipped with brush in both side surface of the quartz glass covered with carbon-coating, after drying naturally again
One layer of brush, then one layer of brush again after drying naturally, 4~5 layers of brush altogether per side, thin layer phosphorus is obtained on quartz glass carbon-coating surface
Sour Argent grain, is made support type silver phosphate photocatalyst.
The beneficial effects of the invention are as follows:
After Quartz glass surfaces obtain polystyrene film by the method for rendering, high temperature cabonization, acquisition carbon-coating, and
Accelerate electron transmission using colloidal property formation catalyst film, obtain preferable degradation effect in carbon-coating surface.
Embodiment
3 embodiments of the present invention are provided further below:
Embodiment 1
In 30cm2Clean Quartz glass surfaces dip in styrene ethanol solution brush that concentration is 6mol/L with brush in quartz
Glass both side surface, places 12h, then one layer of brush in atmosphere after drying naturally, then places in atmosphere after drying naturally
12h, then one layer of brush, per side 5 layers of brush altogether, the styrene of a layers of polymer is obtained in quartz glass both side surface;By the quartzy glass
Glass is placed in Muffle furnace, under nitrogen protection, is progressively warming up to 550 DEG C, and keeps temperature 2h, and the quartz of carbon-coating covering is made
