The ternary compound boron carbonitride (BCN) was synthesized in the form of few-layer nanosheets through a mechanically induced self-sustaining reaction (MSR). Magnesium was used to reduce boron trioxide in the presence of melamine in a combustive manner. The process to form the nanostructured material was very rapid (less than 40 min). The prepared powder was investigated by various techniques such as X-ray diffraction (XRD), Fourier Transform infrared (FTIR), Micro-Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HRTEM), and electron energy loss spectroscopy (EELS). The thermal stability and the optical behavior of the BCN nanosheets were also studied by thermal analysis and UV-vis spectroscopy, respectively. The formation mechanism of the nanosheet morphology was described in detail.
通过机械诱导自维持反应（MSR），以硼碳氮化物（BCN）的形式合成了三元化合物。在燃烧过程中，使用镁还原三氧化二硼，同时使用三聚氰胺作为反应物。形成纳米结构材料的过程非常迅速（不到 40 分钟）。通过 X 射线衍射（XRD）、傅里叶变换红外（FTIR）、微拉曼光谱、X 射线光电子能谱（XPS）、高分辨率透射电子显微镜（HRTEM）和电子能量损失光谱（EELS）等多种技术对制备的粉末进行了研究。还分别通过热分析和紫外可见光谱研究了 BCN 纳米片的热稳定性和光学行为。详细描述了纳米片形态的形成机制。
