Abstract
The invention discloses a kind of preparation methods of perite nanometer piece, belong to environmental chemical engineering photocatalysis water-treatment technology field, tetrabutylammonium hydroxide is dissolved in deionized water by this method, chloride is added, bismuth salt is added again, the precipitating that stirring obtains after standing is cleaned with deionized water and ethyl alcohol, and perite nanometer piece is made after dry;The present invention synthesizes catalysis material with innocuous agents by simple method, meets environmentally protective requirement, which has the ability of stronger degradation of contaminant under visible light or/and full light;There is higher application value in fields such as pollution control, new energy preparation and selective catalytic oxidations.
Description
Technical field
The present invention relates to a kind of preparation method and applications of visible-light response type perite nanometer piece, belong to environmental chemical engineering light
It is catalyzed water-treatment technology field.
Background technique
With the development of dye industry, produces waste water and have become one of currently the most important pollution source of water body;Dyestuff is dirty
Water has the characteristics that color depth, complicated component, COD value are higher and difficult to degrade, brings serious harm to ecological environment.Place at present
The method of reason waste water from dyestuff mainly has: absorption method, membrane separation process, photocatalytic oxidation, electrochemical oxidation process, ultrasonic degradation skill
Art etc..Photocatalytic oxidation has the characteristics that energy-efficient, contaminant degradation is thorough.TiO2It is the photocatalysis being most widely used
Agent, but its wider band gap (~3.2 eV) makes its that only light to wavelength less than 387 nm generates response, and to accounting for solar energy
45~50% wavelength is that the visible light of 400~750 nm does not respond to but.The crystal structure of chlorine oxygen bismuth is PbFCl type, symmetrically
Property: D4h, space group: P4/nmm belongs to tetragonal crystal system.Chlorine oxygen bismuth has layer structure, the chlorine oxygen bismuth atom layer of dual layer arrangement
Between by Cl atom pass through non-bonding force (Van der Waals force) combine.Chlorine oxygen bismuth valence band is mainly O2pAnd Cl3pIt occupies, conduction band is mainly
Bi6pThe contribution of track.The layer structure of chlorine oxygen bismuth high anisotropy is convenient for the separation of photo-generate electron-hole, ensure that bismuth nitrate
Well stable photocatalytic activity;However broad-band gap (~3.4 eV) equally limits utilization of the chlorine oxygen bismuth to visible light.Therefore,
How to make the band-gap energy of chlorine oxygen bismuth reduces, and becomes focus concerned by people using solar energy so as to more sufficiently effective.Currently,
Has the correlative study of some enhancing chlorine oxygen bismuth visible light response activities by wide coverage.Xiong etc. reports auxiliary in mannitol
The lower two-dimentional perite nanometer piece that square is prepared for using hydro-thermal method is helped, the band gap of the catalyst is obviously reduced (~2.92
EV);The catalyst shows good photocatalytic activity to rhodamine B under visible light, and catalyst amount is 0.5 gL-1
When, 10-5 mol·L-1Rhodamine B solution is degradable in 8 minutes (RSC Advances, 2011,1:1542-1553).
The band gap of chlorine oxygen bismuth is reduced to 2.65 eV from 3.5 eV by the irradiation of ultraviolet light by Ye et al..This is because the photograph of ultraviolet light
Penetrating makes to form Lacking oxygen in chlorine oxygen bismuth catalyst body phase.Under visible light illumination, degrading activity of the catalyst to rhodamine B
Than the catalyst before ultraviolet light activity improve nearly 20 times (Phys. Chem. Chem. Phys., 2012,14:
82-85).Chen et al. is prepared for chlorine oxygen bismuth (~2.87 using bismuth trichloride and nitric acid as raw material under l- lysine corrective action
EV) photochemical catalyst.Narrow band gap may be (110) crystal face of the pattern and high exposure due to nano flower-like.In the nm light source of λ >=435
After irradiating 50 min, 10 mgL-1RhB decolourizes completely, and degradation rate constant is up to 0.1186 min-1(Catalysis
Communications, 2012,23:54 ~ 57);Report relevant to the application is had no at present.
Summary of the invention
It is needed for the removing of chlorine oxygen bismuth photochemical catalyst difficulty and the degradation of the organic pollutant of the prior art efficient visible
The problem of photochemical catalyst, the present invention provides a kind of preparation methods of perite nanometer piece, utilize the big of tetrabutylammonium hydroxide
Ion stripping performance makes chlorine oxygen is bismuth laminated to peel away, and the absorption spectrum of chlorine oxygen bismuth photochemical catalyst is widened visible light
Area passes through stirring, precipitating, separation, washing and drying steps system using bismuth salt, chloride and tetrabutylammonium hydroxide as raw material
It is standby to obtain visible-light response type two dimension perite nanometer piece photochemical catalyst.
This method is easy to operate, and raw material is easy to get, is easily achieved and securely and reliably, does not need that strong acid is added;The present invention is four
Chlorine oxygen bismuth through precipitation method preparation under butyl ammonium hydroxide effect is relatively not added under tetrabutylammonium hydroxide effect through precipitating legal system
Standby chlorine oxygen bismuth has stronger visible light catalytic effect to degradation carbamazepine at visible light (> 420nm), while in full light
Under can also degrade sulfamethoxazole and C14H10Cl2NNaO2, preferable degradation effect has all been shown to a variety of Organic substance in water.
Perite nanometer piece of the present invention the preparation method is as follows:
(1) tetrabutylammonium hydroxide is dissolved in deionized water, chloride is added after dissolution, mixed, wherein tetrabutylammonium hydrogen
The molar ratio of amine-oxides and chloride is 1:(0.2 ~ 6);
(2) bismuth salt is added into the mixed solution of step (1), after being stirred 3 ~ 8h, stands 1 ~ 3h at room temperature, wherein chlorine
The molar ratio of compound and bismuth salt is 1:(1 ~ 1.5);
(3) step (2) mixture is filtered, precipitating cleaned with deionized water after again with washes of absolute alcohol 1 ~ 2 time, 40 ~
