Description

A kind of g-C 3n 4nanometer sheet/CdS composite visible light catalyst
Technical field
The invention belongs to the technical field belonging to material preparation and visible light photocatalysis, be specifically related to a kind of two-dimensional ultrathin g-C 3n 4the application of the preparation of nanometer sheet/CdS composite visible light catalyst and under visible light catalytic degradation organic pollutants.
Background technology
Current energy and environment problem is day by day serious, causes the extensive attention in global range.Photocatalysis technology is then the potential desirable route of one solving this two problems of energy and environment.And mainly low, the photochemical catalyst stability of solar energy utilization ratio is not thus cannot recycle to restrict reason that photochemical catalyst applies in actual production at present.Therefore, in order to can better solar energy be utilized, prepare efficient, stable visible light catalyst, to the current energy of solution and environmental problem, there is far reaching significance.
After having found Graphene, two-dimensional material has had the advantages such as unique electricity and optical property and has caused great concern because of it.G-C 3n 4be band gap be 2.7eV visible light catalyst, being the most stable a kind of carboritride, is also a kind of material with stratiform two-dimensional structure, g-C 3n 4and semiconductor compound photocatalyst also there is potential application foreground water-splitting and depollution of environment aspect under visible light.The g-C of block 3n 4there is the defect that photo-generated carrier is easy to compound, the separative efficiency of photo-generate electron-hole is low, and quantum efficiency is low, well can not utilize sunshine.And pass through the g-C of block 3n 4peel off into two-dimensional ultrathin g-C 3n 4after nanometer sheet, not only increase its specific area, more avtive spot is provided, and improve the separative efficiency of photo-generated carrier.The semiconductor of CdS to be energy gap be 2.4eV, has good visible absorption performance.But CdS is easily oxidized by photohole under light illumination and photoetch phenomenon occurs.Photoetch phenomenon makes the bad stability of CdS catalyst, and photocatalytic activity reduces.In order to improve photostability and the photocatalytic activity of CdS, preparing its composite photo-catalyst becomes research emphasis.Due to g-C 3n 4the band structure of mating is had very much between the two, g-C with CdS 3n 4effectively can lead away photohole thus suppression photoetch effect that CdS produces.Based on above analysis, in conjunction with two-dimensional ultrathin g-C 3n 4with CdS advantage separately, prepare two-dimensional ultrathin g-C 3n 4/ CdS compound, can be conducive to the separative efficiency of photo-generated carrier, effectively improves stability and the photocatalytic activity of catalyst simultaneously.
CN10319766A discloses a kind of CdS/g-C 3n 4composite visible light catalyst, preparation method and application.This catalyst is prepared by chemical precipitation method, is applied to the degraded of methylene blue and crystal violet solution under visible ray, has good degradation effect.But that this patent system is standby is block g-C 3n 4, do not possess two-dimensional ultrathin g-C 3n 4the special nature had, is also difficult to realize two-dimensional ultrathin g-C 3n 4the close contact such with CdS, therefore photocatalysis efficiency is low.And we utilize ultrasonic stripping method by block g-C 3n 4peel off into two-dimensional ultrathin g-C 3n 4, and obtained the two-dimensional ultrathin g-C of both close contacts at its surface in situ growth CdS nano particle by solvent-thermal method 3n 4/ CdS visible light catalyst, photo-generated carrier transfer impedance is little between the two, and separative efficiency is high.Experiment proves, two-dimensional ultrathin g-C 3n 4/ CdS composite photo-catalyst is obviously better than block g-C at this pollutant of degraded methyl orange 3n 4the photocatalysis effect of/CdS composite photo-catalyst.
Summary of the invention
One is the object of the present invention is to provide to overcome block g-C 3n 4the deficiency that photo-generated carrier separative efficiency is low, the two-dimensional ultrathin g-C suppressing CdS photoetch, there is efficient visible light activity 3n 4the preparation method of nanometer sheet/CdS composite photo-catalyst, and the application of catalytic degradation organic pollutants under visible light.The two-dimensional ultrathin g-C that the present invention prepares 3n 4nanometer sheet/CdS and general block g-C 3n 4/ CdS compares, two-dimensional ultrathin g-C 3n 4have between nanometer sheet/CdS composite photo-catalyst two material and contact more closely, and specific area is larger, thus photo-generate electron-hole can be separated better, photocatalysis efficiency is higher.
For achieving the above object, the present invention adopts following technical scheme:
Two-dimensional ultrathin g-C of the present invention 3n 4nanometer sheet/CdS composite visible light catalyst is by by block g-C 3n 4peel off into two-dimensional ultrathin g-C 3n 4nanometer sheet, and obtained at its surface in situ growth CdS nano particle by solvent-thermal method.G-C in catalyst 3n 4the mass ratio of nanometer sheet and CdS is 1:100-90:100.
Preparation method comprises the following steps:
(1) melamine or urea are obtained block g-C through calcining, cooling, grinding 3n 4;
(2) by block g-C 3n 4join in isopropyl alcohol, ultrasonic 5-20 hour, form the suspension of dispersion; Low-speed centrifugal removes thicker block g-C 3n 4, then the suspension remained by high speed centrifugation, the dry ultra-thin g-C obtaining two dimension 3n 4nanometer sheet;
(3) by the ultra-thin g-C of two dimension 3n 4nanometer sheet joins in the ethanolic solution of two acetate hydrate cadmiums, and ultrasonic, stirring, forms homodisperse suspension;
(4) in the suspension of step (3), add thioacetamide, stir after making it to dissolve completely, carry out solvent thermal reaction;
(5) by the ultra-thin g-C of step (4) products therefrom through centrifugal, washing, dry obtained two dimension 3n 4nanometer sheet/CdS composite visible light catalyst.
In step (1), calcining heat is 400-600 DEG C.
Described catalyst is used for the visible light photocatalytic degradation of target contaminant in water.
Described target contaminant is methyl orange.
Remarkable advantage of the present invention is: two-dimensional ultrathin g-C of the present invention 3n 4nanometer sheet/CdS catalyst is at preparation method, structure composition and catalytic performance and existing CdS/g-C 3n 4catalyst is different.Because the present invention is by the g-C of stripping method by block 3n 4peel off into two-dimensional ultrathin g-C 3n 4nanometer sheet, with block g-C 3n 4compare, two-dimensional ultrathin g-C of the present invention 3n 4nanometer sheet not only increases its specific area, provides more avtive spot, and improves separative efficiency and the photocatalysis efficiency of photo-generated carrier.This composite photo-catalyst, under sunlight, has good catalytic degradation effect to this kind of organic pollutants of methyl orange.Preparation method of the present invention is simple to operate, and raw material are easy to get, and visible light catalytic efficiency is high, has broad application prospects in photocatalysis field.
