Abstract
The invention relates to a method for preparing a novel function material, particularly to a method for preparing micro silver oxide simply, conveniently and rapidly. The method comprises the following steps: feeding sodium hydroxide solution in a test tube, sealing the test tube opening with a micro-filtration membrane, filling a beaker with a silver nitrate solution, standing the test tube upside down and fixing the test tube in the beaker to ensure that the micro-filtration membrane is below the liquid level in the beaker, leaving to stand for 0.5-12 hours, and separating and washing a product in the beaker to obtain the micro silver oxide. According to the method for preparing micro silver oxide, the applied articles are vessels commonly used in a lab and the micro-filtration membrane easily purchased on the market, the devices are simple, convenient and rapid, and easy to assemble and demount, no organic adding agent or surfactant is used in the preparation process, high temperature and high pressure are avoided, and the size of an obtained silver oxide cube can be controlled through adjusting the solution concentration.
Description
Technical field
The present invention relates to a kind of method preparing new function material, be specifically related to a kind of simple and convenient method preparing micron silver suboxide.
Background technology
Along with the development of science and technology, micro Nano material is more and more subject to people's attention, and nano material is a kind of brand-new material, generally refers to that particle diameter is less than the ultrafine particle of 100nm.It is large that this ultrafine particle has surface-area, and surfactivity is high, good catalysis characteristics, and it not only has metal but also have nonmetallic specific performance.Due to the property of nano material, make its potential application in all fields very extensive.Nano material has important using value in technical fields such as national defence, electronics, nuclear technique, metallurgy, aviation, light industry, medicine, thus has started the peak of nano material preparation and research.
Because micro Nano material shows character distinct with macroscopical block materials.In a lot of situation, the character of micro Nano material depends on its pattern showed.Silver suboxide is the oxide compound of a class silver, in a lot of, have application, and as being used as chemosynthesis catalyzer, zinc-silver oxide battery is medium.In prior art, work out multiple method and prepared the different silver suboxide micro Nano material of pattern.But most preparation process all needs organic additive or tensio-active agent to regulate and control the pattern of silver suboxide, too much introducing organism is not a green syt process.Micron silver suboxide cubic block has unique character, and how to invent a kind of simple and convenient method preparing micron silver suboxide cubic block square and become those skilled in the art's technical problem urgently to be resolved hurrily.
Summary of the invention
The present invention is in order to solve the problems of the technologies described above, and providing a kind of can prepare the method for micron silver suboxide by simple and fast, specifically comprises following technical scheme:
A kind of method preparing micron silver suboxide, comprise the following steps: sodium hydroxide solution is loaded in test tube, test tube mouth is sealed by microfiltration membrane, splendid attire silver nitrate solution in beaker, test tube is stood upside down, is fixed in beaker, ensure below the liquid level of filter membrane in beaker, leave standstill 0.5 ~ 12 hour, in separating, washing beaker, product can obtain a micron silver suboxide.
The volume ratio of described beaker and described test tube is 5 ~ 10:1, and the mean pore size of the filter opening of microfiltration membrane is 0.2 micron.
Described concentration of sodium hydroxide solution is 0.04 ~ 0.2 mol/L, and described silver nitrate solution concentration is 0.05 mol/L.
The volume ratio of described sodium hydroxide solution and described silver nitrate solution is 4 ~ 20:1.
Beneficial effect of the present invention comprises: a kind of method preparing micron silver suboxide of the present invention, use article for commonly using the microfiltration membrane that vessel and market are easily bought in laboratory, device is simple and convenient, easy assembling is quick detachable, preparation process does not use any organic additive and tensio-active agent, do not use High Temperature High Pressure, gained silver suboxide cubic block size controls by regulator solution concentration.
