Abstract
The invention belongs to environmentally conscious materials synthesis technical fields, and in particular to a kind of preparation method of the conductive traces Ag@PANI/CoFe2O4/C with good photocatalytic activity and selectivity;First using the C that corncob converts as carrier load C oFe again2O4CoFe is synthesized2O4Simultaneously loaded Ag has synthesized Ag@PANI by/C, simultaneously synthesizing PANI, then has synthesized final material by template molecule of tetracycline.Advantage of the invention is that:Imprinted layer uses grafting, visible light-initiated method step by step, has the advantages such as bonding success rate is high, polymerization speed is fast, realizes the selective removal of tetracycline;The method that Ag@PANI use external synthesis, are generally introduced has the advantages such as accounting is controllable, preservation is complete, photocatalysis performance is good, is promoted while realizing photocatalytic activity and selectivity;Abandoned biomass(Corncob)Use not only embody the meaning of the treatment of wastes with processes of wastes against one another and also reduce production cost.
Description
Technical field
The invention belongs to environmentally conscious materials synthesis technical fields, and in particular to a kind of conductive traces Ag@PANI/CoFe2O4/ C's
The research of preparation method and its selective absorption/photocatalytic degradation tetracycline.
Background technology
CoFe2O4As novel semiconductor material, there is good photocatalytic activity and Magneto separate characteristic, be special both at home and abroad
One of the active material of family's scholar's research.But common CoFe2O4Cannot from numerous substances selective removal specific objective object, this
Seriously constrain CoFe2O4Functionalized application.And the introducing of surface imprinted technology can well solve CoFe2O4Function
Change application.
Surface imprinted technology is to polymerize template molecule in polymer monomer solution with crosslinking agent, obtains solid Jie
Matter, then by either physically or chemically eluting the template molecule removed in medium, obtaining " trace " has target molecule space knot
The surface imprinted polymer of structure and binding site, it can be envisaged that:Under the conditions of solution environmental, a series of function monomer and template
Molecule meets, and can make these by hydrogen bond, electrostatic interaction, hydrophobic effect and other non-covalent interactions between them
Functional molecular can arrange in the form of with template molecule the structure mutually order state of complementation to each other.But use surface
When engram technology modifies common catalysis material, light degradation activity is caused to substantially reduce since active site is capped, and
Conducting polymer is introduced in surface imprinted layer can efficiently solve the above problem.
Conducting polymer, also known as conducting polymer can effectively conductive semiconductor quilts with good electric conductivity
Light induced electron caused by excitation, and then the separative efficiency of light induced electron-photo-induced hole of material is improved, to improve material
Photocatalytic activity.
In addition, carbon material has good specific surface area and chemical property is stablized, it is extraordinary carrier material, on it
Load C oFe2O4CoFe can be improved2O4Dispersibility, inhibit CoFe2O4Reunion, can also be material load or cladding
More binding sites are provided, while the specific surface area of material can also be increased, improve its adsorption capacity.And corncob is as allusion quotation
The waste biomass material of type, the meaning of the treatment of wastes with processes of wastes against one another can not only be embodied by being converted into carbon material as raw material, additionally it is possible to
Production cost is reduced, there is huge development potentiality.In the prior art in surface imprinted layer conducting polymer introducing, generally adopt
The method being polymerize together with imprinted polymer and conducting polymer, but this method poor controllability, it cannot be guaranteed that conducting polymer
