Description
Technical field
The invention belongs to catalysis material technical fields, more particularly, to a kind of foamed nickel supported silver carbonate complex light
Catalysis material and its preparation method and application.
Background technique
In recent years, due to semiconductor TiO2Catalysis material have good chemistry, biological stability, it is environmentally friendly,
The advantages that low cost and long service life can be nontoxic water and titanium dioxide organic pollutant mineralizing and degrading different in water body
Carbon has been increasingly subject to the extensive concern of researcher.However, TiO2Photochemical catalyst can only be by ultraviolet excitation, and powder is deposited
Recycling the disadvantages of difficult.The response of research novel visible, Yi Huishou photochemical catalyst have become one and curb environmental pollution
Hot topic.
In recent years, a series of Ag base optic catalytic material such as Ag2S、Ag3PO4And Ag2CO3Deng and other types of semiconductor light
Catalysis material shows excellent photocatalytic activity when being compounded in degradable organic pollutant under radiation of visible light.However, these Ag
There is also be difficult to the shortcomings that separating and recovering and reusing for powder of the base composite photocatalyst after light-catalyzed reaction.Photochemical catalyst
Fixed load technology be one of the effective way to solve the above problems.Spongy porous nickel foam is a kind of excellent three-dimensional
Material.It has the characteristics that unique open-celled structure, tensile strength height and heat shock resistance and is widely used as catalysis material
Carrier.Silver carbonate catalysis material is loaded in nickel foam not only can be improved its photocatalytic activity, but also be also easy to silver carbonate
The recycling and reusing of powder.For example, application No. is a kind of " the carbon cloth loads of the Chinese invention patent of CN201810631635.X
MoS2/Ag3PO4The preparation method of composite photocatalyst material ", preparation method is that (1) successively with acetone, ethyl alcohol and goes carbon cloth
Ionized water cleaning, then carries out surface acid etching and drying；(2) mixing for clean carbon cloth being immersed in sodium molybdate and thiocarbamide is molten
In liquid and hydro-thermal reaction, make to grow molybdenum disulfide on carbon cloth；(3) carbon cloth that surface grows molybdenum sulfide is successively immersed in nitre
In the solution of sour silver and disodium hydrogen phosphate, carbon cloth is made and loads MoS2/Ag3PO4Composite photocatalyst material.Though above-mentioned preparation method
So be conducive to the recycling and reusing of catalysis material, still, process preparation process is complicated, has limitation.For another example application number
For the Chinese invention patent " load type titania photocatalyst and preparation method " of CN03132906.3, preparation method is,
The tetrabutyl titanate having had been prepared for is added dropwise in the nitric acid that concentration is 1M, forms colourless transparent solution after being vigorously stirred；So
After distilled water is added, after stirring with sodium hydroxide solution adjust pH=1~2, be vigorously stirred until formed white suspension；It takes
The Bio-sil of 100 to 200 mesh is added in suspension, then pH=3~4 of this suspension are adjusted with sodium hydroxide solution, is connect
Suspension is separated by solid-liquid separation, is washed, until supernatant pH value be greater than 6；Obtained solid is dried；It is calcined under high temperature, it is cold
But it is supported on the surface of Bio-sil after in the form of nano particle up to titanium dioxide, and mass ratio is (1~2): (1~6)
Photochemical catalyst.Although this method improves the recycling and reuse of catalysis material to a certain degree, TiO2It can only be in purple
Organic matter in the outer lower sewage that could degrade of light irradiation, practical application have limitation.
Summary of the invention
In order to solve above-mentioned the shortcomings of the prior art, primary and foremost purpose of the present invention is to provide a kind of nickel foam
Load silver carbonate composite photocatalyst material.
Another object of the present invention is to provide the preparation methods of above-mentioned foamed nickel supported silver carbonate composite photocatalyst material.
The preparation method simple process had not only enhanced photocatalysis stability but also had solved photocatalytic powder asking of being difficult to recycle to a certain extent
Topic.
