The preparation of boron nanosheets has very strict requirements of the preparation environment and substrate. In this work, the boron nanosheets were tried to prepare by the grinding method, using β-B alloy with stable chemical properties and large crystal plane spacing. Its morphology and chemical bonds of boron nanosheets were analyzed by scanning microscope (SEM), transmission microscope (TEM), and X-ray photoelectron spectroscopy (XPS). The results show that the two-dimensional boron nanosheets can be prepared from β-B powder by the grinding method. There are very few B-O bonds in boron particles, and the B-B bonds are principally dominant. In addition to a few B-O bonds, including some B-B bonds change to BO bonds which are not completely oxidized, indicating that boron has certain oxidation resistance.
硼纳米片的制备对制备环境和基底有非常严格的要求。在这项工作中，尝试采用研磨法制备硼纳米片，使用化学性质稳定且晶面间距大的β-B合金。通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）和X射线光电子能谱（XPS）对硼纳米片的形貌和化学键进行了分析。结果表明，通过研磨法可以从β-B粉末制备出二维硼纳米片。硼颗粒中B-O键很少，主要以B-B键为主。除了少数B-O键外，包括一些未完全氧化转变为BO键的B-B键，这表明硼具有一定的抗氧化性。
