The method comprises the following specific processes: firstly, preparing gold nanoparticles and loading the gold nanoparticles on the surface of a substrate; and then, directly accessing the gold nanoparticles loaded on the substrate into a power supply or placing the gold nanoparticles on the surface of a heating medium accessed into the power supply, introducing instantaneous large current of 50-200A to two ends of the sample or the heating medium, rapidly heating the sample or the heating medium to 1400-2500K, and keeping heating for 5-60 seconds to enable gold atoms to diffuse to the outer surface to form a hollow structure. The method for preparing the hollow gold nanospheres by using the instantaneous large-current rapid heating sintering method is rapid and simple, has low cost, and the prepared hollow gold nanospheres have stable structures and high specific surface areas and have wide application prospects in the fields of biomedicine, optics, energy catalysis and the like.
Description
Technical Field
The invention belongs to the field of material preparation, and particularly relates to a method for forming a hollow structure of gold nanoparticles by rapid sintering.
Background
The gold nanoparticles have unique surface structure, optical characteristics, stability and biocompatibility, so that the gold nanoparticles are widely applied to the fields of biomedicine, optics, energy catalysis and the like. The gold nanoparticles with hollow structures can realize the modulation of the characteristic absorption wavelength from a visible light region to a near infrared light region, and are beneficial to photo-thermal treatment of organisms. Meanwhile, the unique cavity of the hollow gold nanosphere is proved to have unique plasma and optical properties, and can absorb spectral red shift to form a photo-thermal conversion reagent. In addition, compared with solid gold particles, the hollow gold has higher specific surface area and lower noble metal content, so that the catalytic activity of the gold nanoparticles is improved, and the cost is reduced.
In order to obtain hollow nanostructures, a conventional method is a template method, in which a template is used as a core of a hollow sphere structure, a shell material is introduced on the surface of the template, and finally the core is removed to form an internal hollow structure. However, the template method involves final template removal, and on one hand, the operation procedure is complex, a sacrificial agent exists, and the cost is high; on the other hand, the microsphere structure is also damaged to a certain extent. In addition, there are liquid phase methods, high temperature dissolution methods, spraying methods, etc., but these methods usually involve various chemicals participating in the reaction, and introduce impurities, resulting in impure products. And the nano material can be agglomerated in a liquid phase, and the long-time high-temperature treatment can also cause the problems of particle growth and the like, which are not favorable for the application of the hollow nano gold. Therefore, a simple, fast and low-cost method for preparing high-purity hollow nano-gold is urgently needed to be found so as to promote the practical application of the hollow nano-gold in the fields of biomedicine, optics, energy catalysis and the like.
