Abstract
The invention provides a rapid low-cost preparation method of gold nanoparticles. The preparation method comprises the following specific steps: chloroauric acid is added to edible oil, and is mixed at room temperature for 5min, and the gold nanoparticles are obtained. Compared with other preparation methods, the preparation method does not involve a complicated chemical reaction system and uses low-cost safe edible oil, so that the preparation cost is reduce substantially. In addition, in a preparation process, the response time, the reaction temperature, the concentration of chloroauric acid, the use times of edible oil have very little influence on the sizes of the final gold nanoparticles, thus the preparation process requires no complicated reaction condition control, and industrial production is facilitated. The prepared gold nanoparticles are good in conductivity, and can be widely applied in the industry of electronic information and the like.
Description
Technical field
The invention belongs to technical field of nano material, and in particular to a kind of quick, low cost golden nanometer particle preparation side
Method.
Background technology
Golden nanometer particle is all widely used in many fields, for example material detection, electronic circuit, catalysis, optics
Deng.The first step of golden nanometer particle application is exactly to prepare qualified golden nanometer particle.In conventional report, golden nanometer particle
It is main reacted in organic solvent by using gold chloride and some reducing agents obtaining (Chem.Mater.2007,19,719-
726；Chem.Mater.2011,23,3312-3317；Nano Lett.2016,16,617-623).The price of gold chloride is very high,
The price of chemicals and organic solvent is also higher, and this causes the preparation cost of final golden nanometer particle very high, significantly impacts
Its application.Meanwhile, these report preparation methods be also required to the longer reaction time, be unfavorable for it is quick, prepare Jenner on a large scale
Rice corpuscles.Finally, organic solvent and organic chemical pollution environment, its processing cost and the reaction environment for bringing are polluted to reducing
It is all unfavorable for golden nanometer particle preparation cost, Protection personal security.
To solve these problems and advancing the application of golden nanometer particle, simple, cheap, quick, free of contamination Jenner is found
Rice corpuscles preparation method is just very necessary.
The content of the invention
The invention provides a kind of quick, inexpensive, free of contamination golden nanometer particle preparation method.Relative to former side
Method, the present invention is prepared using the edible oil of inexpensive safety, and its preparation cost, post processing cost are substantially reduced.Importantly,
In preparation process of the present invention, time, temperature, concentration affect very little, edible oil to make repeatedly the size of final nano-particle
With, therefore the preparation of golden nanometer particle of the present invention does not need precise control reaction condition, This further reduces golden nanometer particle
Preparation cost.These advantages make golden nanometer particle of the present invention great competitive advantage in price, can be in electronic information etc.
Industry is extensively applied.Detailed preparation process is：
(1) take a certain amount of edible oil and be added to stirring in a container；
(2) and then by gold chloride it is added in edible oil, stirs to reaction and terminate；
(3) after standing, edible oil is gone, is then cleaned, obtain pure golden nanometer particle.
Edible oil used of the invention includes soybean oil, corn oil, peanut oil, rapeseed oil, linseed oil, grape-kernel oil, purple
Soviet Union's oil, walnut oil, apricot kernel oil, Seabuckthorn Oil, evening primrose oil, borage oil, sesame oil, sunflower oil, cottonseed oil, small oil, fire
Sesame oil, siritch, camellia seed oil, peony seed oil, palm oil, walnut oil, coconut oil, olive oil etc..Can be independent when using
A kind of oil, or two or more oily mixing.Container used includes vial, stainless steel cauldron, glass
The popular response device such as reactor, beaker, conical flask.After oil is added in container, stirring is opened.Then it is being kept stirring for
In the case of, gold chloride is added in oil, gold chloride dissolves immediately and begins with solid generation, and solution colour is changed into black from transparent
Brown；
Reaction time, reaction temperature, gold chloride concentration, edible oil access times affect on the size of final golden nanometer particle
Very little.In 5-180 minutes, the scope of 10-150 DEG C, 0.01-0.30 gram gold chloride/20 milliliter oil, the golden nanometer particle of acquisition
Size it is essentially the same.Meanwhile, edible oil access times do not have impact substantially on its size, within 5 times, Jenner's grain of rice of acquisition
The size of son keeps constant.The size of final golden nanometer particle is between 300nm to 700nm；
After reaction terminates, a few minutes are stood, golden nanometer particle is deposited to completely container bottom.Supernatant liquor is poured into into one
In individual bottle, preserve, remain to use next time.The solvent of dissolvable edible oil is subsequently adding, after stirring a few minutes, supernatant liquor is inclined
.It is repeated several times by this process, you can obtain pure golden nanometer particle；
The solvent of cleaning edible oil of the invention used be the one kind in ethanol, isopropanol, methyl alcohol, acetone, ethyl acetate or
Several mixing；
The present invention has the following advantages：(1) in addition to gold chloride and edible oil, other reactive materials are not required to, reaction is simple, peace
Entirely；(2) whole process is in addition to reaction vessel and agitator, it is not necessary to by other instruments, not by centrifugation purifying, pair sets
Standby requirement is very low；(3) reaction time, reaction temperature, gold chloride concentration, edible oil access times are to final golden nanometer particle
Size affect very little, preparation process is easily controlled, the golden nanometer particle size uniformity of acquisition；(4) in addition to gold chloride, other
Cost is negligible, and total production procedure is quick, inexpensive, pollution-free, facilitates industrial production.
