Description

A kind of individual layer hexagon Ag 3pO 4/ Fe 3o 4the preparation method of/Co-Ni LDH composite
Technical field
The invention belongs to photocatalyst technology field, be specifically related to a kind of individual layer hexagon Ag 3pO 4/ Fe 3o 4the preparation method of/Co-Ni LDH composite.
Background technology
2010, magazine " nature " reported a kind of visible-light photocatalyst silver orthophosphate (Ag with strong oxidizing property 3pO 4), this Novel silver phosphate photocatalyst absorbing wavelength can be less than the sunshine of 520nm, quantum yield under visible light up to 90%, and creates strong oxidability under visible light, in the degradation experiment of many organic dyestuff, all show extremely superior photocatalysis performance.As a kind of emerging material, photochemical catalyst can utilize sunshine processing environment pollutant, for mankind's Environment control opens an effective new way.Titanium dioxide (TiO 2) there is high catalytic activity, good chemical stability, with low cost, the characteristics such as safety non-toxic are one of green catalysts studying hottest point at present.But most of catalyst such as titanium dioxide can only produce catalytic activity under ultraviolet light (accounting for 5% of solar radiation), and low sunshine utilization rate makes photocatalytic activity restricted greatly.As a kind of functional material, photochemical catalyst should possess following characteristics: high activity and high efficiency; Stability and anti-poisoning capability is kept under high temperature, long-time reaction; Mechanical stability and wear resistance; Keep physical stability and chemical property under various conditions; Raw material prepared by photochemical catalyst are cheap.
Azo dyes refers to the dyestuff of the azo structure containing connection two aromatic radicals (singly do not refer to aryl radical, also refer to the hydridization alkyl containing armaticity) in dye molecule, and general formula is Ar-N=N-Ar '.Azo dyes is connected with aromatic ring system the chromogen of formation conjugated system as dyestuff.This kind of dyestuff is with a long history, and synthesis is convenient, and stable in properties is cheap, is extensively liked.If textile garment uses the azo dyes containing forbidding, with the Long Term Contact of human body in may to produce absorb by the skin of human body, spread in human body, if can not discharge via metabolism in time, under the condition that these dyestuffs react in the metabolism of human normal, may reduction reaction be there is, and then decomposite carcinogenic aromatic amine.Carcinogenic aromatic amine, via activation, changes the DNA structure of human body, finally causes human body mutagenesis and cause cancer.
Methyl orange is a kind of typical azo dyes, and micro-poison, is difficult to biodegradation.Printing dye discharge capacity containing methyl orange is large, and organic concentration is high, is difficult to biodegradation, is the industrial wastewater received much concern.Therefore, a kind of material of methyl orange of can degrading need be found.
