Abstract
Disclosed is a method for preparing gamma-AlOOH and gamma-Al2O3 through ionic-liquid-assisted hydrothermal synthesis. The method is characterized in that divalent metal ions are utilized to drive a decomposition reaction of a precursor so as to generate gamma-AlOOH in a mild condition. The method comprises main steps: 1) dissolving aluminium salt, an ionic liquid and divalent metal ions in deionized water according to different ratios, and performing uniform stirring; 2) transferring the obtained solution to a reactor and performing a reaction at different reaction temperatures for a while; 3) after the reaction is over, performing cooling to the room temperature, performing centrifugalization, performing alternate washing with deionized water and absolute ethanol, and performing drying to obtain a precursor of gamma-AlOOH; and 4) putting the precursor of gamma-AlOOH in a muffle furnace, and carrying out calcination to obtain a gamma-Al2O3 nanometer material with the identical shape. According to the method, gamma-AlOOH in the shape of a needle-shaped crystal whisker, a nanotube, and a bamboo-leaf-shaped nanometer flower and gamma-Al2O3 converted from gamma-AlOOH are synthesized. The obtained gamma-Al2O3 is relatively high in degree of crystallinity and specific surface area and has comparatively high potential of large-scale production.
Description
Technical field
The invention belongs to field of inorganic nano material.It is specifically related under temperate condition, ionic liquid auxiliary synthesis Gao Bibiao
Area γ-aluminum oxyhydroxide, and as presoma, the method for the thermally treated gama-alumina obtaining identical pattern.The present invention can
Hope for pottery, catalysis, optics, adsorb, separate, photoelectricity turns device, the field such as nano material and composite.
Background technology
In numerous nonmetal and transition metal oxide materials, aluminium oxide because of have aboundresources, cheap, compare table
The features such as area is big and chemical stability is good and nontoxic, exchange at catalysis, ion, the field such as adsorbent and pottery has suitable
It is widely applied.The particularly low-temperature stabilization phase gama-alumina surface of aluminium oxide has abundant hydroxyl, is absorption and catalysis neck
The alumina material being most widely used in territory.In view of the processes such as absorption and catalysis occur mainly in the surface of material, gamma oxidation
The surface texture of aluminum plays pivotal role in the application.Though amorphous gama-alumina has the highest specific surface area (＞ 800m2/
G), but its poor heat stability and microstructural stability seriously restrict its application in catalytic process, and improve material
Degree of crystallinity is to improve material heat stability and the effective means of microstructural stability.Therefore, explore that degree of crystallinity is higher, specific surface area
The synthetic technology of big gama-alumina nano material is still current problem demanding prompt solution.
Gama-alumina nano material can pass through the side of the presomas such as heat treatment aluminium carbonate, aluminium hydroxide and hydrated alumina
Method obtains.So far, people by the approach such as liquid phase method and vapor phase method, successfully prepare the gama-alumina nanometer of different appearance
Material, such as: nanometer rods, nano wire, nanotube, nano hollow structure and pore structure etc. (Adv.Funct.Mater., 2007,17,
2411-2418；J.Mater.Chem., 2008,18,442-449；J.Phys.Chem.C, 2007,111,700-707；

2652).But, these methods also exist following several respects problem: it is generally required to add template, surfactant or other is auxiliary
Helping reagent, the purge process making product is complex, and the removal process of auxiliary reagent also may cause the broken of product micro structure
Bad, what is more important surface rearrangement often results in the reduction of gama-alumina nano material surface active；Part Methods exists
Need to add volatility or toxic organic solvents, reaction temperature is higher or needs two steps to prepare, and could obtain γ-hydroxyl oxidize
The problems such as aluminum presoma.Though the existing Patents of the preparation of gama-alumina nanotube, such as: CN201110327588,
CN200910035950 and CN200510086373 etc., but method therefor is that electrostatic spinning, surfactant are as template etc.
Method, there are still the common problem of other solution chemical method documents.Therefore, under conditions of more gentleness, exploitation low energy consumption,
Environmental friendliness, method are easy, equipment requirements is low and are suitable for the preparation method of gama-alumina nano material of large-scale production,
It is still one of key technology of meeting gama-alumina Application of micron demand.
Summary of the invention
Key issue to be solved by this invention is: provide the Hydrothermal Synthesis that the ionic liquid under a kind of temperate condition assists
Method, to realize γ-aluminum oxyhydroxide presoma that degree of crystallinity is higher, specific surface area is bigger, before being thermally treated resulting in succession
The method driving the gama-alumina nano material of bodily form looks.Product has higher degree of crystallinity and higher specific surface area, it is expected to should
For fields such as catalysis and absorption, and there is the feasibility of higher large-scale production.
The scheme that the present invention uses is: under the hydrothermal condition of ionic liquid auxiliary, by adding Zn2+The metals such as ion from
Son, utilizes the complexing power of metal ion as driving force, promotes the decomposition reaction containing aluminum intermediate product, to realize temperate condition
The synthesis of lower γ-aluminum oxyhydroxide.In the present invention, the addition of metal ion reduce reaction precursor decomposition temperature, and from
The addition of sub-liquid then achieves effective control of product morphology.γ-the aluminum oxyhydroxide of synthesis is thermally treated, is crystallized
Degree is preferable, surface area is higher, and pattern keeps good gama-alumina nano material.
The preparation process of the present invention is as follows:
First, by the AlCl of 2mmol3·6H2Zn (the NO of O, 1mmol3)2·6H2The CH of O, 5mmol3COOK and a certain amount of
Ionic liquid be sequentially added into, be dissolved in the deionized water of 15mL, be stirred until homogeneous.
Second, above-mentioned prepared clear solution is moved to in teflon-lined stainless steel cauldron, juxtaposition
In baking oven, at a temperature of differential responses, react a period of time.Being cooled to room temperature, product is performing centrifugal separation on, and uses deionized water
With dehydrated alcohol alternately washing, it is dried.Obtain γ-aluminum oxyhydroxide presoma.
3rd, collect the γ-aluminum oxyhydroxide presoma obtained, be placed in muffle furnace, at 600 DEG C, calcine 2h, obtain
Gama-alumina nano material.
