Abstract
The present invention discloses a quaternary hybrid magnetic composite functional material and a preparation method thereof. The composite material is a quaternary hybrid of Ag@AgX, reduced graphene oxide and magnetic nanomaterials. First, the surface of the rGO is sequentially in situ deposited with Fe3O4, MnFe2O4, ZnFe2O4, CoFe2O4 and other iron-based magnetic nanomaterials and grown with AgX precipitate so as to obtain rGO/MFe2O4/AgX ternary complex nanomaterials; and then the ternary complex nanomaterials are exposed to a mercury lamp to obtain the quaternary hybrid magnetic composite material rGO/MFe2O4/Ag@AgX. The material not only has the magnetically responsive property and externally applied magnetic field controllability of magnetic particles, the high adsorption performance, electrical conductivity and other properties of graphene nanomaterials, the photocatalytic property of plasma material Ag@AgX, but also has the surface enhanced raman spectroscopy activity of Ag particles, and the synergistic effect between Ag@AgX and graphene materials enhances the photocatalytic property of Ag@AgX and the SERS activity of Ag, so that the detection limit of the substance to be detected is increased. The material has great potential application value on one-step concentration, magnetic separation, SERS detection and in situ photocatalytic degradation and other aspects of low concentrations of benzene ring organic pollutants in water.
Description
Technical field
The invention belongs to technical field of nano material, relate to a kind of quaternary hydridization magnetic sewage purification material and preparation method thereof.
Background technology
INDUSTRIAL ORGANIC POLLUTANTS, especially with aromatic rings organic pollution major part can long-term existence in environment and organism, cause adverse influence to the sustainable development etc. of ecological environment, people ' s health, social safety and economic society, the environmental problem caused thus more and more receives publicity.And Environment control mainly contains two tasks: one is carry out detection to pollutant to analyze; Two is remove pollutant.
SERS (Surface-enhanced Raman Scattering, SERS) information of the technology molecular level that other detection techniques can be provided to be difficult to obtain, have short, water interference detection time little, do not destroy sample when detecting, do not need to carry out complex process to sample, can the advantage such as direct in-situ analysis, detection range be wide, the fingerprint characteristic of testing sample can also be provided simultaneously, can unknown material be distinguished by these fingerprints, realize the super sensitivity detection to object and identification.The more important thing is, the peak width that the vibration peak width of SERS spectrum compares other spectrum is very narrow, decrease probability overlapping between peak with peak, therefore for multicomponent detection provides possibility, cause the broad interest of scholars in many fields such as bioanalysis and environment pollution detection.In addition, photocatalysis degradation organic contaminant has the advantages such as nontoxic, efficient, cheap because of it, has become new energy-efficient environmental pollution improvement's method.But all just simple the detecting pollutant and remove of these two kinds of techniques and methods, can not realize purifying a step enrichment of pollutant, highly sensitive detection and ira situ degradation, more can not realize recovery and the recycling of scavenging material.
Graphene oxide (GO), because it has large specific area and highly delocalized pi-electron conjugated system, can adsorb several organic molecule containing phenyl ring with " π-π " stacking effect simultaneously.In addition, functionalization can also be carried out easily in the surface of graphene oxide, modify with functional groups such as hydroxyl, carboxyl, amino and sulfonic acid, increase on the one hand its dissolubility in water and stability, on the other hand be convenient to carry out coupling compound with other part or nano particle, thus with some complexes or give its more functionalization.Just because of having these obvious advantages above, the application of GO in the detection, purification etc. of water pollutant causes to be paid attention to widely.
Therefore, TiO is compared for problem noted earlier with according to the one that nearest researcher proposes
2more can improve the novel surface plasma photocatalysis materials A gX(X=Cl of catalysis material to the utilization rate of visible ray, Br, I), we have proposed the rGO/ Fe being applied to water pollutant process field
3o
4multi-functional the constructing of/Ag@AgX quaternary hybridization compounding nano material, current also rarely seen report.This composite gathers multi-function in integral whole, and can realize a step enrichment of organic pollutants, highly sensitive detection, Magneto separate and ira situ degradation and purify.Simultaneously, after the nano particles such as Ag@AgX and graphene nano Material cladding, cooperative effect between the two can make the surface reinforced Raman active of Ag and the photocatalytic activity of AgX be enhanced, and is expected to the new unit developing sensitiveer and effective detection and ira situ degradation water micropollutants.
