Description
Technical Field
The invention belongs to the technical field of composite nano materials, and relates to a three-dimensional hollow molybdenum disulfide @ gold nanoparticle and a preparation method thereof.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
In recent years, a two-dimensional material of a transition metal sulfide represented by molybdenum disulfide has attracted much attention due to its excellent physicochemical properties and its potential application to electronic/photoelectric devices, sensors, energy storage, lithium batteries, and the like. MoS2Is a two-dimensional layered structure, each layer is composed of S-Mo-S through covalent bonds, and the layers are combined through weak van der Waals force, so that the MoS with single layer or few layers can be formed by destroying the van der Waals force between the layers through stripping, ultrasonic method and the like2Nanosheets. Layered MoS with nanoscale2Has the properties of large specific surface area, more active sites, adjustable band gap and the like. In the practical application process, the two-dimensional layered MoS2The nanoplatelets are easily stacked, resulting in a reduction of active sites. In order to solve the problem, the two-dimensional nanosheets can be assembled into a three-dimensional structure, so that the advantages of the two-dimensional nanomaterial are fully realized; in addition, MoS can also be grown on a three-dimensional template2Etching off the attached template to form the hollow MoS with nano three-dimensional structure2. Lou et al as MnCO3Cubic block is used as a template, and MoS is subjected to a hydrothermal method2The nano-sheet grows on MnCO3On the cubic block, form MnS @ MoS2A core-shell structure, and etching off the MnS inside by an acid washing method to obtain layered MoS2A hollow cube. In summary, building three-dimensional structures is an important way to maintain their nanoscale features in practical applications.
On the other hand, the gold nanoparticles can generate electromagnetic field regulation and photo-thermal effects and the like through the action with an incident light field. When electromagnetic waves are incident on a metal, free electrons on the surface of the metal oscillate collectively, and if longitudinal waves propagating along the surface of the metal oscillate, the longitudinal waves are called conducted surface plasmons, and if the oscillations are localized on the surface of a structure or in a gap, the longitudinal waves are called localized surface plasmons. The local surface plasmons can concentrate the energy of incident light on or near the surface of the metal, effectively enhancing the electromagnetic field at these locations. The locally enhanced electric field provided by the gold nanoparticles may thus enhance light absorption, intensity of light and substance interaction, and the like. The local surface plasmon intensity and peak elimination position have important relations with metal materials, particle size and morphology, the gold nanoparticles have a tunable electric field enhancement effect in the range from visible light to near infrared light, and the gold nanoparticles have good chemical stability, so that the gold nanoparticles are widely concerned.
The gold nanoparticles and the molybdenum disulfide form a composite structure, and the characteristics of the gold nanoparticles and the molybdenum disulfide can be utilized to play a role. For example, gold nanoparticles and molybdenum disulfide are proved to have surface Raman enhancement effect, the gold nanoparticles have high enhancement factor but are easy to damage the biomolecule structure and have poor reproducibility, and the molybdenum disulfide has the characteristics of fluorescence inhibition and good biocompatibility but has low enhancement factor. Various achievements have reported the enhancement of the raman enhancement effect after the gold nanoparticles are compounded with molybdenum disulfide. It should be noted that, in these reports, molybdenum sulfide nanosheets are firstly obtained by chemical vapor deposition or stripping, and then are compounded with gold nanoparticles. So far, there are few reports on the formation of composite structures by wet chemical methods, especially there is no report on the direct composition of tubular structures during the formation of gold particles, and there are few studies on the application of such composite structures in other fields, although the principle is feasible. Based on the current situation, the invention provides a composite micron particle and a preparation method thereof, wherein the composite micron particle has a NaYF structure4：Yb/Er@MoS2The @ Au is obtained by converting the above materials into a template and synthesizing the template through a hydrothermal method, and whether a hollow structure is obtained in one step can be selected by controlling the using amount of sodium citrate, so that the micron particles with the composite structure have application prospects in the fields of molecular detection, photoelectric response, photocatalysis and electrocatalysis.
