Description
Technical Field
The invention belongs to the technical field of nano materials, and relates to a two-dimensional metal oxide nanosheet and a preparation method thereof.
Background
The metal oxide nano material has wide application potential in the fields of energy, catalysis, materials, environment, electronics, biomedicine and the like due to excellent electric, optical, thermal, mechanical and other properties. The metal oxide nanosheet with the two-dimensional structure has the characteristics of high specific surface area, short carrier migration distance, high activity and the like, and is widely applied to the fields of energy, catalysis, environmental protection and the like.
Due to the huge application prospect of two-dimensional metal oxide nano materials, researches on synthesis and morphology control of metal oxide nano sheets are increasing in recent years, wherein how to synthesize non-layered metal oxide nano sheets becomes the focus of research. At present, the synthesis methods of the non-layered metal oxide nanosheets mainly include the following methods: the method comprises a nanocrystalline self-assembly method, a two-dimensional orientation connection method, a layered precursor auxiliary stripping method, a two-dimensional template synthesis method and a local chemical transformation method, wherein the two-dimensional template method is most widely applied. Among many two-dimensional templates, graphene oxide having a two-dimensional structure is most widely used because the graphene oxide surface contains a large amount of oxygen-containing groups to facilitate interaction with a metal precursor.
Because the two-dimensional template agent cannot realize real two-dimensional confinement, the key of synthesizing the metal oxide nanosheet by the two-dimensional template method is how to enable the precursor to uniformly grow a thin layer of nanoparticles or nanoparticle precursors on the surface of the two-dimensional template agent through precise regulation and control, and in the process, the nanoparticles can not be independently generated in a solution, and crystals or aggregates with larger sizes can not be grown on the surface of the template agent. To solve this problem, the existing research works adopt various methods, and fine control is usually needed to realize the growth of nanoparticles on the surface of a two-dimensional template agent, and the control is usually specific: different metals require different conditions and methods. This makes these preparation methods not universally applicable, only to specific metals or to specific classes of metals. Meanwhile, due to the severe reaction conditions, the prepared metal oxide nanosheet is generally low in yield, high in cost and difficult to prepare in large quantities. Therefore, developing a new method for synthesizing two-dimensional metal oxide nanosheets with low cost, high universality, high efficiency, high controllability and capability of mass preparation is still an important challenge for practical application of the two-dimensional metal oxide nanosheets.
