Description
Technical field
The present invention relates to a kind of metal organic frame two-dimensional nano pieces and preparation method thereof, belong to the skill of nanostructure synthesis
Art field.
Background technique
Metal organic framework compound (MOFs) is a kind of crystalline state porous material with periodic network structure, by metal
(single metal ion or metal cluster) and organic ligand are self-assembly of by coordinate bond.MOFs is also referred to as coordination polymer
(coordination polymer) be a kind of hybrid inorganic-organic materials, has the rigidity and organic material of inorganic material concurrently
Flexible characteristic.MOFs can form different frame pore structures, this is because metal (single metal ion or metal cluster)
Arrangement with organic ligand has apparent directionality.Therefore, MOFs has that high porosity, high-specific surface area, duct be regular, hole
Diameter is adjustable and topological structure diversity and the advantages that Scalability, stores up in catalysis, nonlinear optics, ion exchange and gas
There is potential application in depositing and separating.(Kitaura R, Kitagawa S, Kubota Y, et al. Formation of
a one-dimensional array of oxygen in a microporous metal-organic solid.[J].
Science, 2002,298 (5602): 2358-2361.)
In recent years, traditional blocky MOF cannot fully meet many specific application demands, especially for biofacies
Application is closed, MOF needs smaller size to promote it to enter in cell, such as biomedical imaging, drug delivery and biology
Sensing etc., therefore the synthesis of the nanoscale MOF crystal with controlled dimensions and pattern has become an emerging topic.Nanoscale
The surface area of MOF is greater than the surface area of bulk MOF, its performance in terms of separation, catalysis and sensing is caused to improve.(Furukawa
S, Reboul J, Diring S, et al. Structuring of metal-organic frameworks at the
mesoscopic/macroscopic scale[J]. Chemical Society Reviews, 2014, 43(16):5700-
5734.) therefore, the synthesis of nanoscale MOF is most important.
There are mainly two types of methods for the synthesis of 2D MOF nanometer sheet, first is that synthetic method from top to bottom, this method is from blocky MOF
Upper removing；Second is that synthetic method, party's rule directly synthesize 2D MOF nanometer sheet using metal and organic ligand from bottom to top.
(Zhao M, Lu Q, Ma Q, et al. Two-Dimensional Metal-Organic Framework
Nanosheets [J] Small Methods, 2016,1 (1-2): 1600030.)
ZIFs is the one kind for reacting generation in organic solvent by the metal salts and imidazate or derivatives thereof such as divalent Zn, Co ligand
MOFs material with class skeleton structure of zeolite.Imidazate is a kind of five-membered ring with conjugated nature, by losing a matter
Son and metallic ion coordination, formed a connection type correspond exactly to Si-O-Si structure in zeolitic material, bond angle close to
145 ° of M-IM-M (M: transition metal ions；IM: imidazate), so ZIFs material combines metal-organic framework materials and boiling
The double dominant of stone, not only high porosity and bigger serface and adjustability of structure with MOFs material, but also there is inorganic boiling
The high stability of stone.(Park K S, Ni Z, C t é A P, et al. From the Cover:Exceptional
chemical and thermal stability of zeolitic imidazolate frameworks[J]. Proc
Natl Acad Sci U S A, 2006,103 (27): 10186-10191.) therefore, ZIFs material has latent at many aspects
Application value, such as gas absorption separation, ion exchange, chemical industry catalytic process and gas storage.
ZIF-8 is by metal Zn2+The ZnN to be formed is connect with the N atom in MIM4Tetrahedral structural unit.The aperture ZIF-8
0.34 nm, 11.6 nm of cage diameter, the feature with bigger serface and small-bore macropore cage.For electrical energy storage device,
Excellent electrode material has high surface area, high conductivity and good structural stability, and ZIF-8 during electric discharge-charging
The requirement can be reached as template and precursor.In addition to this, it can be synthesized by the ammonia treatment in situ in annealing process
The derivative carbide material of porous ZIF-8 with controllable pore size distribution.Therefore, ZIF-8 is successfully applied to lithium ion battery
(LIB) anode, the cathode of lithium-sulfur cell (LSB) and the component and supercapacitor of other battery systems.
Although the duct ZIF-8 is regular, large specific surface area, aperture is small, skeleton structure is open, structure is adjustable, various structures,
Be since its size is larger, so cannot be introduced into cell, and specific surface area, aperture cannot reach requirement in some applications,
And 2D ZIF-8 nanometer sheet has many advantages, such as easy film forming, large specific surface area, active site exposure, has development prospect.
Bottom-to-top method is used in the present invention.The critical issue of this method needs to limit MOF vertically
Growth, and growth transversely is unaffected., using easy anionic surfactant assisted synthesizing method, surface is living for we
Property agent not only limit the growth of MOF vertically, and help to disperse synthesis after size MOF nanometer sheet.
