Description
Technical field
The invention belongs to technical field of nano material, and in particular to a kind of quick, low cost gold nanoparticle preparation side
Method.
Background technology
Gold nanoparticle is all widely used in many fields, such as substance detection, electronic circuit, catalysis, optical device
Deng.The first step of gold nanoparticle application is exactly to prepare qualified gold nanoparticle.In previous report, gold nanoparticle
Mainly reacted in organic solvent by using gold chloride and some reducing agents obtain (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, this causes the manufacturing cost of final gold nanoparticle very high, significantly impacts
It is applied.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, processing cost and the reaction environment brought are polluted to reducing
It is all unfavorable for gold nanoparticle manufacturing cost, Protection personnel safety.
To solve these problems and the application of gold nanoparticle is promoted, find simple, cheap, quick, free of contamination Jenner
Rice corpuscles preparation method is just very necessary.
Invention content
The present invention provides a kind of quick, low cost, free of contamination gold nanoparticle preparation methods.Relative to pervious side
Method, the present invention prepare the edible oil using inexpensive safety, and manufacturing cost, post processing cost substantially reduce.Importantly,
In preparation process of the present invention, time, temperature, concentration influence very little to the size of final nano-particle, and edible oil can make repeatedly
With, therefore the preparation of gold nanoparticle of the present invention does not need to accurately control reaction condition, This further reduces gold nanoparticles
Manufacturing cost.These advantages make gold nanoparticle of the present invention great competitive advantage in price, can be in electronic information etc.
Industry extensive use.Detailed preparation process is：
(1) a certain amount of edible oil is taken to be added in a container to stir；
(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, obtains pure gold nanoparticle.
Edible oil used in the present invention includes soybean oil, corn oil, peanut oil, rapeseed oil, linseed oil, grape seed 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..In use, can be independent
A kind of mixing of oil or two or more oil.Container used includes vial, stainless steel cauldron, glass
The popular responses device such as reaction kettle, beaker, conical flask.After oil is added in container, stirring is opened.Then it is being kept stirring
In the case of, gold chloride is added in oil, gold chloride dissolves and begins with solid generation immediately, and solution colour becomes black from transparent
Brown；
Reaction time, reaction temperature, gold chloride concentration, edible oil access times influence the size of final gold nanoparticle
Very little.In 5-180 minutes, 10-150 DEG C, the oily range in 0.01-0.30 grams of gold chloride/20 milliliter, the gold nanoparticle of acquisition
Size it is essentially the same.Meanwhile edible oil access times do not have influence substantially on its size, and within 5 times, Jenner's grain of rice of acquisition
The size of son remains unchanged.The size of final gold nanoparticle is between 300nm to 700nm；
After reaction, a few minutes are stood, gold nanoparticle is deposited to container bottom completely.Supernatant liquor is poured into one
In a bottle, preserve, remain next use.Then the solvent that can dissolve edible oil is added in, after stirring a few minutes, supernatant liquor is inclined
.It is repeated several times this process, you can obtain pure gold nanoparticle；
The solvent of cleaning edible oil of the invention used is ethyl alcohol, isopropanol, methanol, acetone, one kind in 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 other than reaction vessel and blender, does not need to, by other instruments, not purify by centrifugation, pair sets
Standby requirement is very low；(3) reaction time, reaction temperature, gold chloride concentration, edible oil access times are to final gold nanoparticle
Size influence very little, preparation process is easily controlled, the gold nanoparticle size uniformity of acquisition；(4) in addition to gold chloride, other
Cost can be neglected, and total production procedure is quick, inexpensive, pollution-free, facilitates industrial production.
