Description
Technical field
The present invention relates to technical field of nanometer material preparation, and in particular to a kind of rapid precipitation prepares basic copper sulfate two dimension
The method of nanometer sheet.
Background technique
Basic copper sulfate (Cu2(OH)2SO4) belong to metal hydroxides, because its special crystal structure kills it medical
It bacterium and is agriculturally widely used.In addition, its Derived Oxides has this substance extensively in fields such as energy storage, catalysis
Potential application.Rapid, high volume, which prepares this electrode material and synthesis ionic conductor material, has wide application prospect.Especially,
Special two-dimensional structure has the electronic and ionic conduction orientation of orientation, and powerful stress ability to bear and short axial ion pass
Defeated path, it is considered to be particularly significant nano material branch.Existing preparation Cu2(OH)2SO4Method be using copper sulphate and hydrogen
Calcium oxide is mixed with, and this method is difficult to pattern, size, and structure is controlled, and complex process, and impurity content is high.In addition,
Although higher using basic copper sulfate purity prepared by urea, the disadvantages such as grain diameter is big, and specific surface is low.And
CuSO4NaCO is added dropwise in solution3It is prepared, but its preparation but nanometer little particle, is not had two-dimensional material feature.
Therefore, two-dimentional Cu can simply, quickly be prepared by inventing one kind2(OH)2SO4The method of nanometer sheet material will be in future
Industrialization, and widely apply production it is particularly important.The precipitation method have efficient, quick, succinct etc. a variety of in preparing material
Outstanding feature.But simultaneously, the quick crystallization of precipitation reaction makes preparation, regulates and controls along specific dimension nano material: such as two-dimentional
Nano material has very big challenge.
Summary of the invention
For the prior art is insufficient or Improvement requirement, the present invention provides a kind of rapid precipitation and prepares two wiener of basic copper sulfate
The method of rice piece, the huge challenge of two-dimension nano materials is regulated and controled caused by the quick crystallization the method overcome precipitation reaction,
Prepare two-dimension nano materials Cu2(OH)2SO4.For the present invention using ammonium hydroxide as precipitating reagent, water is solvent, utilizes the low dissociation system of ammonium hydroxide
Number slowly releases OH-Ion, so that being grown according to two-dimensional directional of can orienting during the growth process of material.
To achieve the above object, the invention is realized by the following technical scheme:
The present invention provides a kind of method that rapid precipitation prepares basic copper sulfate two-dimensional nano piece, which is characterized in that with copper sulphate
It is raw material with ammonium hydroxide, is synthesized by liquid-phase precipitation method, specific steps are as follows:
Step 1, at 25-30 DEG C, by percentage to the quality, by 70-80% copper sulphate and 20-30% ammonia solvent Yu Shuizhong, and
Persistently stir 10-20 minutes；
The copper sulphate is the aqueous solution of concentration 0.3-0.8%；
The ammonium hydroxide is the aqueous solution of concentration 0.09-0.11%；
Step 2 is separated 5-10 minutes, is obtained shallowly by mixed material supercentrifuge obtained by step 1 with 3500-5000r/min
Blue precipitate；
Step 3 cleans light blue sediment obtained by step 2 3-5 times with ethyl alcohol；
Step 4, by step 3 resulting material 60-80 DEG C dry 5-12 hours to get basic copper sulfate two-dimensional nano piece.
Ethyl alcohol used is 96% ethanol solution in the step 3.
Compared with prior art, the beneficial effects of the present invention are: the present invention carries out material system using the liquid phase room temperature precipitation method
Standby, compared with conventional hydrothermal method, this method is easy to operate, and prepared product morphology is novel, quality is stablized.
