Description
Technical field
The invention belongs to photocatalysis field, and in particular to a kind of to peel off the ultra-thin Bi prepared by silver-colored intercalation12O17Cl2Nanometer
Piece photochemical catalyst and its preparation method and application.
Background technology
With the fast development of Chinese economy, environmental degradation and energy shortage problem are also increasingly prominent.This is solved two to ask greatly
Topic be China realize sustainable development, improve people's living standard and safeguard national security there is an urgent need to.Photocatalysis technology quilt
It is considered one of preferable solar energy switch technology, it is in water process, air purification, hydrogen production by water decomposition, CO2Reduce and artificial
The fields such as photosynthesis have potential advantages.
Two-dimension nano materials are a kind of new materials with infinitepiston size, it is believed that are that three-dimensional crystal is thinned
To material obtained from one or several atomic layer level thickness.Because of its unique thickness and design feature, can not only strengthen
The intrinsic performance of material, and there may be the new feature that some do not have for body phase material.
Photocatalytic redox reaction is carried out on surface, therefore the surface texture of semi-conducting material exposure urges its light
Changing activity has decisive role.And two-dimension nano materials have high specific surface area, the exposure ratio in high activity site, body phase
The features such as migration distance of photo-generated carrier is minimum, these all cause two-dimensional material has in terms of photocatalytic applications potentially should
Use prospect.
So far it has been reported that stratiform two-dimension nano materials preparation method mainly have mechanical stripping method, liquid phase ultrasound
Stripping method and intercalation stripping method.Wherein, the low output of mechanical stripping method, size are difficult to control；Liquid phase stripping method is similarly deposited
Charge stripping efficiency is low, unmanageable thickness the shortcomings of.And the yield of intercalation stripping method is then of a relatively high, and the nanometer sheet synthesized is thick
Spend controllable.What is be most widely used in intercalation stripping method is to insert lithium to peel off（Li J, Zhan G, Yu Y, et al. Superior visible light hydrogen evolution of Janus bilayer junctions via atomic-level charge flow steering[J]. Nature communications, 2016, 7.）, but insert
Lithium reagent is usually metallo-organic compound, and this kind of compound is very active, easily reacts with water and oxygen, this just leads
Cause the reaction condition more harsh.It is, thus, sought for more suitably intercalation species, and silver-colored intercalation peel off rule can be well
Solve the problems, such as these.

By AgNO3Ethanol water is added dropwise, after stirring 0.5 ~ 2 h at room temperature, illumination（λ>= 420 nm）0.5 ~ 2 h, centrifugation point
It is washed with deionized, is dried in vacuo from after, ultra-thin Bi is made12O17Cl2Nanosheet photocatalyst；
The volume ratio of ethanol and water is 1 in the ethanol water:1；
Step（1）The ethanol water that the faintly acid ethanol water is adjusted for dilute HCl, pH=4 ~ 6；
Step（1）The ethanol water that the strong basicity ethanol water is adjusted for NaOH or KOH, pH=12 ~ 14.
Step（2）The ultra-thin Bi being prepared12O17Cl2Silver-colored mass fraction is the % of 0.1 % ~ 1 in nanometer sheet.
Block Bi12O17Cl2The thickness of nanometer sheet is 20 ~ 40 nm.

The present invention provides a kind of above-mentioned ultra-thin Bi12O17Cl2Nanosheet photocatalyst and above-mentioned preparation method are made
Ultra-thin Bi12O17Cl2Application of the nanosheet photocatalyst in rhodamine B degradation.This application comprises the following steps：Will be described super
Thin Bi12O17Cl2Nanosheet photocatalyst and rhodamine B the solution mixing and absorption under the conditions of lucifuge；By the mixed liquor in 300 W
Xenon light shining（λ>= 420 nm）The min of lower progress light-catalyzed reaction 5 min~60, completes the degraded to rhodamine B.
The innovative point of the present invention is：Present invention firstly provides the method peeled off using silver-colored intercalation to prepare ultra-thin Bi12O17Cl2
Nanometer sheet, this method not only realizes thickness regulation and control, but also silver-colored simple substance is successfully introduced between nanoscale twins, in the two factors
Coupling under, ultra-thin Bi12O17Cl2The photocatalysis performance of nanometer sheet is compared to block Bi12O17Cl2Nanometer sheet has greatly
Ground is lifted.
Compared with prior art, the advantage of the invention is that：
（1）First passage of the present invention utilizes Ag+And Cl-Between high forces, in ethanol water pass through self-assembling technique will
Ag+It is inserted into block Bi12O17Cl2Nanometer sheet [Bi12O17]2+[Cl2]2-Interlayer, and using photo-reduction method by Ag+Conversion
For Ag simple substance, as Ag simple substance is in interlayer nucleation and growth process, Bi12O17Cl2The interlamellar spacing of nanometer sheet becomes larger therewith, interlayer Van der Waals force
Also it can be weakened, Bi is peeled off so as to reach12O17Cl2The effect of nanometer sheet.The preparation method has easy to operate, cost of material
It is low, energy consumption less, can be achieved prepare with scale the advantages that, belong to green synthesis techniques；
（2）The ultra-thin Bi of the present invention12O17Cl2Nanosheet photocatalyst photocatalysis effect is splendid, ultra-thin under the same terms
Bi12O17Cl2Nanosheet photocatalyst 87.2 % rhodamine Bs of catalytic degradation in 20 min, and block Bi12O17Cl2Nanometer sheet
