Description
The present invention is that application No. is the division Shens of the patent of invention on 30 days November 2016 201611090880.1, applying date
Please.
Technical field
The invention belongs to nano metal particles preparing technical fields, and in particular to a kind of preparation side of gold nanoparticle
Method.
Background technology
In previous report, gold nanoparticle is mainly anti-in organic solvent by using gold chloride and some reducing agents
(Chem.Mater.2007,19,719-726 should be obtained；Chem.Mater.2011,23, 3312–3317；Nano
Lett.2016,16,617-623).The price of gold chloride is very high, and the price of chemicals and organic solvent is also higher, this causes
The manufacturing cost of final gold nanoparticle is very high, significantly impacts its application.Meanwhile these report preparation methods be also required to compared with
The long reaction time, be unfavorable for it is quick, prepare gold nanoparticle on a large scale.Finally, organic solvent and organic chemical pollute environment,
Its processing cost and the reaction environment brought pollute for reduction gold nanoparticle manufacturing cost, Protection personnel safety
It is all unfavorable.To solve these problems and the application of gold nanoparticle is promoted, finds simple, cheap, quick, free of contamination gold nano
Particle preparation method is just very necessary.
Invention content
Present invention aims at provide a kind of to prepare that stability is good, preparation method of gold nanoparticle simple for process.
The object of the invention is realized by following technical solution：
A kind of preparation method of gold nanoparticle, as follows：
(1) it takes a certain amount of edible oil to be added in a container to stir；
(2) and then by gold chloride it is added in edible oil, stirring to reaction terminates；The concentration range of the gold chloride is
0.01-0.30 grams of gold chloride/20 milliliter edible oil；
(3) after standing, edible oil is gone, is then cleaned, pure gold nanoparticle is obtained.
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 oil can also be the mixing of 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, preserves, remain next use.Then the solvent that can dissolve edible oil is added, 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 be 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, pacifies
Entirely；(2) whole process is other than reaction vessel and blender, need not be purified by centrifugation by other instruments, 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 is negligible, and total production procedure is quick, inexpensive, pollution-free, facilitates industrial production.
Generally speaking, relative to pervious method, the present invention prepares the edible oil using inexpensive safety, manufacturing cost,
Post processing cost substantially reduces.Importantly, in preparation process of the present invention, time, temperature, concentration are to final nano-particle
Size influence very little, it can be used repeatedly for edible oil, therefore the preparation of gold nanoparticle of the present invention need not accurately control instead
Condition is answered, This further reduces the manufacturing costs of gold nanoparticle.These advantages make gold nanoparticle of the present invention in valence
Great competitive advantage on lattice, can be in the industries extensive use such as electronic information.
