The photocatalytic materials comprise graphite type carbon nitride and silver phosphate. The prepared photocatalytic materials have photocatalytic activity within the wavelength coverage of 400nm-800nm, and photocatalytic oxidation degradation can be carried out on organic compounds in the radiation of visible light or natural light.
Description
Technical field
The present invention relates to a kind of novel photocatalysis material.
The invention still further relates to the preparation method of above-mentioned catalysis material.
The invention still further relates to the purposes of above-mentioned catalysis material.
Background technology
At present, due to the raising of industrialization degree and the increase of automobile quantity, the pollution of empty G&W is more and more serious, and processing waste gas and waste water has a lot of methods, but photocatalysis method has many good qualities, such as cheap, nontoxic, non-secondary pollution etc.For catalysis material, at present the many of use is titanium dioxide, but titanium dioxide can only be by ultraviolet excitation, and therefore exploitation can more and more be caused by the novel photocatalysis material of excited by visible light scholars' attention.Document has reported that silver orthophosphate has the ability of good Visible Light Induced Photocatalytic organic pollution, but silver orthophosphate is afraid of acid, less stable, and therefore, exploitation phosphoric acid money base composite photocatalyst material is a kind of huge challenge.
Summary of the invention
Meaning of the present invention is to provide a kind of composite photocatalyst material of efficient stable, and this catalysis material can be by excited by visible light, and the activity of extraordinary photocatalysis to degrade organic matter matter is arranged, and preparation process is easy simultaneously, cost is very low.
Catalysis material provided by the invention is graphite mould carbonitride silver orthophosphate compound particle.
The preparation method of graphite mould carbonitride silver orthophosphate composite photocatalyst material provided by the invention is as follows:
A certain amount of silver nitrate is dissolved in a certain amount of distilled water and is made into certain density silver ionized water solution (solution 1); Then a certain amount of graphite mould carbonitride is scattered in wherein; A certain amount of ammonium phosphate is dissolved in a certain amount of distilled water and is made into certain density phosphate radical solution (solution 2); Solution 2 slowly is added drop-wise in the solution 1 that contains the graphite mould carbonitride, after continuing to stir certain hour, by the precipitation suction filtration produced, uses successively distilled water and absolute ethanol washing, then 80 ℃ of vacuum drying 12h obtain corresponding catalysis material.Photocatalytic activity test concrete grammar and the condition of separating methyl orange in visible radiation decline are as follows:
The active testing of catalysis material carries out in homemade quartz reactor.Employing 300W xenon lamp (λ > 400nm) be radiating light source, the methyl orange aqueous solution that reactant liquor is 100mL10mg/L, the concentration of catalyst is 1g/L.Speed with 30mL/min passes into air, under lasting stirring, every 2min, extracts a small amount of reactant liquor, measures solution absorbance at the 463nm place.Determine solution concentration according to the concentration of methyl orange-absorbance calibration curve again.
