Description

Preparation method of millimeter-scale one-dimensional single-crystal gold wire
Technical Field
The invention belongs to the field of preparation of low-dimensional micro-nano metal materials, and particularly relates to a preparation method of a millimeter-scale one-dimensional single-crystal gold wire.
Background
The one-dimensional micro-nano material has the advantages of high length-diameter ratio, large specific surface area, rich reactive sites and the like, and is a research hotspot in the field of materials in recent years. One-dimensional single crystal gold wires are widely used in the fields of electronics, photoelectricity, catalysis, sensing and the like due to excellent electromagnetic properties, catalytic properties, stable physicochemical properties and the like.
However, the controllable preparation of one-dimensional single-crystal gold wires, especially single-crystal gold wires having a length of the order of millimeters, is a difficult point of recent research. The search of the prior art shows that Chinese patent document No. CN 105568356A, the publication date of 2016, 5, month and 11, discloses a method for preparing gold nanowires by using a porous alumina film, the method firstly prepares a porous alumina template, and 1mol/L tetrachloroauric acid solution is deposited in the porous alumina template by an alternating current deposition (deposition voltage of 10V, frequency of 50Hz) method to obtain gold wires with the diameter of less than 100 nanometers and the length of less than 1 micrometer. The method relates to a complex template preparation process, toxic and harmful substances such as perchloric acid, phosphoric acid, chromic acid and the like are required, and the obtained gold wires are small in size and low in yield.
Also, as shown in Chinese patent document No. CN 107217280A, published in 2017, 9 and 29, a method for preparing a gold nanowire array with centimeter-sized length is disclosed, which is carried out in vacuum (less than or equal to 10)-3Pa) in an all solid state environment, with the aid of an externally applied direct current electric field (current intensity: 3-5 muA) to synthesize the gold nanometer structure (the diameter of the gold nanometer wire is distributed between 63 and 102 nm). However, although the gold wire array obtained by the method reaches centimeter level, the single crystal gold wire in the array still has nanometer scale, and the method needs high-purity gold as a material source, needs to be configured with a specific evaporation workbench, and needs to pre-deposit the fast ion conductor Rb4Cu16Cl13I7The surface of the prepared gold wire array is rough and is distributed with a large amount of gold nano particles.
In order to improve the above problems and realize green production of high-length one-dimensional single-crystal gold wires, liquid-phase chemical reduction synthesis has received attention from researchers. Single crystal gold nanowires of about 1.6nm in diameter and about 4 μm in length were synthesized at room temperature by simply mixing tetrachloroauric acid (gold source) and oleylamine (both as reducing agent and capping agent) solutions as in the literature (Nano Letters,2008,8(7): 2041-. Also, as shown in chinese patent document No. CN 109056073 a, published in 2018, 12 and 21, a method for rapidly synthesizing a hydrophilic and clean-surface single-crystal ultrafine gold-silver alloy nanowire is disclosed, in which N, N-dimethylformamide is used as a solvent, chloroauric acid, silver nitrate, a surfactant and a reducing agent are added to the system, and the mixture is stirred in an ice-water bath and heated to obtain a gold-silver alloy nanowire with a diameter of less than 2 nm. At present, because of the insufficient development of reducing agents and end capping agents, the controllability of the reduction speed and the end capping effect of a liquid phase reduction method is poor, so that the sizes of gold wires in the existing reports are limited to the nanometer level, and large-size single crystal gold wires with millimeter-level length are not found. Moreover, the preparation of one-dimensional single-crystal gold wires without strong coordination end-capping agents on the surface and with stable morphological properties still has some technical problems, such as complex preparation process, harsh reaction conditions, difficult industrial mass production and the like.
