Method for preparing layered boron material through liquid phase method

Abstract

The present invention relates to a method for preparing a layered boron material through a liquid phase method. The method comprises: (1) adding a metal boride into a dispersant containing an oxidizing agent at a room temperature under a normal temperature, and carrying out a reaction to obtain a layered boron material and a metal salt; and (2) washing the material obtained after the reaction in the step (1) to remove the metal salt, and drying the remaining material to obtain the layered boron material.

Description

technical field [0001] The invention belongs to the field of synthesis methods of layered boron materials. More specifically, the present invention relates to a method for rapid preparation of boron materials by liquid phase method at normal temperature and pressure. Background technique [0002] Layered boron is a thermodynamically stable phase of elemental boron. Through calculation and simulation, layered boron materials with fewer layers can produce a certain band gap and exhibit special carrier transport properties (J.Am.Chem .Soc.2014,136,12257-12260 / Nano Energy.23(2016)97–10 / RSC Adv.,2015,5,74399–74407 / Nat.Commun.,2014,5:3113). In addition, its bandgap can be adjusted in a wide range by various means such as changing the number of layers and doping heteroelements. In recent years, layered boron has become a research hotspot in the field of layered materials. However, there are many difficulties in the actual preparation of layered boron. At present, only a single la...

Problems solved by technology

However, there are many difficulties in the actual preparation of layered boron. At present, only a single layer of boron was deposited on the metal Ag (111) based on the high-temperature and high-vacuum sputtering method published in Science in 2015. The research shows that the single-layer boronene indeed exhibit special metallic transport properties
