Progress in the mild synthesis of superhard single crystal β-BC2N nanorods

The synthesis of superhard materials and their properties have always been one of the important directions of condensed matter physics and materials science research. As a potential new superhard material, many theoretical calculations and experimental studies have shown that the properties of cubic boron-carbon nitrogen (c-BCN) are similar to those of diamond and cubic boron nitride (c-BN), but they have more than diamond. High anti-oxidation ability and higher hardness than c-BN, can be used as high-quality cutting tools, wear-resistant materials, corrosion-resistant protective layers, short-wavelength optoelectronic devices and so on. Based on the broad application prospects of boron-carbon nitrogen compounds, scientists have conducted extensive and in-depth research on the synthesis of boron-carbon nitrogen compounds, and have made fruitful progress. In the field of superhard materials research, BC2N research is a frontier topic. Practice has shown that the synthesis of BC2N is still difficult. In addition to the traditional high temperature and high pressure technology, low temperature, low pressure and low cost synthesis of BC2N is a challenging subject. It is undoubtedly of great research value to find a simple, chemically controllable and operability method for the preparation of boron-carbon nitrogen materials under mild conditions.
Recently, the research group led by the high-invention professor of Yanshan University adopted a simple and easy-to-operate solvothermal synthesis method to obtain a β-BC2N nanorod structure containing trace oxygen defects under mild reaction conditions by controlling experimental conditions. The method avoids extreme conditions such as high temperature and high pressure required for preparing a boron carbon nitride material by a conventional solid phase reaction, and not only reduces the reaction temperature to about 500 ° C, but also obtains a good product morphology and high quality of crystallization. Through first-principles theoretical calculations, they also simulated and gave the possible structure and characteristics of the boron-carbon nitrogen compound, pointing out that the product is a good semiconductor material with a hardness of about 80 GPa, second only to diamond. This is the first time in the synthesis of ternary boron-carbon nitrogen superhard materials to successfully prepare single crystal nanostructures by low temperature and low pressure. This work has opened a new way to gently prepare other boron carbonitrides. The relevant results have been published in famous magazines. "Crystal Growth & Design".
