Background technology
Incretion interferent is a kind of exogenous substances, it can interfere with the synthesis of organism natural hormone, secretion, with reference to,
Effect and removal, so as to influence the dynamic equilibrium of organism, breeding, growth and behavior.This kind of material has that concentration is low, harmfulness
Greatly, the features such as more difficult removal, increasing concern is received in sewage disposal.Bisphenol-A is a kind of typical endocrine disruption
Thing, it is used to polycarbonate synthesis, epoxy resin, fire retardant and other chemical products, had wide range of applications.Thus need
The persistent pollutant that the catalyst gentle, cheap, that physical and chemical performance is stable, photo-catalysis capability is strong of research comes in degradation water,
To ensure that industrial production is lived with people, its destruction to environment is reduced, and then realize sustainable economic development.
Due to environment and energy problem be present, searching can convert solar energy into chemical energy and catalytic activation persulfuric acid
The light fenton catalyst of salt is extremely urgent, synthesize visible region have it is response, simple, stably, efficient photochemical catalyst still
It is a huge challenge.Titanium dioxide is stable because its is nontoxic, and good photocatalytic activity turns into most widely used at this stage
Semiconductor light-catalyst.But.The absorption region of titanium dioxide is in ultraviolet region, and ultraviolet light is only accounted for into atmosphere too
5% or so of sunlight energy, it is too low for the utilization rate of solar energy, although it is compound many titanium dioxide being modified nowadays occur
Material, but the light Fenton catalysis material for designing synthesizing new is still particularly significant.This project is catalyzed to studying new smooth Fenton
Material is significant.
Carbonitride/metal oxide is that one kind is formed by supermolecular mechanism and metal ion with g-C3N4 coordinations
Advanced composite material (ACM).Its precursor polymer semiconductor graphite phase carbon nitride possesses stable physical and chemical performance, well
Medium electron energy band（2.7eV）, turn into a kind of very attracting photocatalysis and light Fenton material, its is nontoxic, inexpensive, stable
Characteristic can apply in numerous areas, such as photolysis water hydrogen, photocatalytic degradation of dye, light Fenton degradation of contaminant, surpass
Level capacitor etc..But g-C3N4 is there is also shortcomings, such as light induced electron recombination rate is high, and solar energy utilization ratio is relatively low, than
Surface area less etc..In order to solve these problems, it is necessary to be modified to g-C3N4.So far, it yet there are no and utilize oversubscription
Son effect and coordination, the related work of carbonitride/iron carbonyl nano composite material is prepared to hydro-thermal reaction with fabricated in situ
Skill technology occurs.
The content of the invention
To solve the deficiencies in the prior art, object of the present invention is to provide a kind of visible light-responded carbonitride/hydroxyl
The synthetic method of the light Fenton agent of base iron nano composite material, the existing carbonitride specific surface area of this method solution is low, ferrous ion
Easily oxidation, the more low reason of persulfate activation rate and the problem of cause photocatalytic activity low.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that：
A kind of synthetic method with visible light-responded nitride porous carbon/iron carbonyl nanometer rods complex light Fenton material,
Comprise the following steps：
Step 1, melamine is fitted into porcelain boat, temperature reaction 4 hours in argon atmosphere, then in nitrogen atmosphere
Middle cooling, the final carbonitride for obtaining yellow shape, grind into powder；
Step 2, product prepared by step 1 load beaker, add isopropanol solvent, are put into continual ultrasonic in ultrasonic machine
4h, carbonitride macromolecular ultrasound, which is peeled off, turns into nitridation carbon quantum dot；
Step 3, appropriate ferric nitrate is added in the carbonitride that step 2 has been peeled off, magnetic agitation is uniform, is then adjusted with PH
Section agent pH is adjusted to 10,30 DEG C of temperature constant magnetic stirring half an hour, mixed liquor is transferred in reactor, 100 DEG C reaction 10h it
Afterwards, product is centrifuged, 60 DEG C of dry 24h, obtain carbonitride/iron carbonyl nano composite material in an oven.
A kind of foregoing synthesis with visible light-responded nitride porous carbon/iron carbonyl nanometer rods complex light Fenton material
Method, the argon atmosphere in step 1 is that argon gas flow velocity is 50cc/min.
A kind of foregoing synthesis with visible light-responded nitride porous carbon/iron carbonyl nanometer rods complex light Fenton material
Method, the condition of the temperature reaction in step 1 include：Started to warm up from room temperature to 540 degrees Celsius to 600 degrees Celsius；It is per minute
Rise 2.3 DEG C.
A kind of foregoing synthesis with visible light-responded nitride porous carbon/iron carbonyl nanometer rods complex light Fenton material
Method, the nitridation carbon quantum dot in step 2 is single-layer silicon nitride carbon.
A kind of foregoing synthesis with visible light-responded nitride porous carbon/iron carbonyl nanometer rods complex light Fenton material
Method, the power bracket of the ultrasonic machine in step 2 are arranged between 700 watts.
