以三聚氯氰（C3 N3 Cl 3）为原料，分别与NaNH 2、K或NaN 3反应，在低温下合成了具有石墨状或洋葱状层状结构的氮化碳。采用X射线粉末衍射、元素分析（C-N燃烧）、X射线光电子能谱、傅里叶变换红外光谱、拉曼光谱、质谱、场发射扫描电子显微镜、透射电子显微镜和高分辨电子显微镜对合成的样品进行了研究。首次获得并观察到了具有类石墨层状结构的氮化碳。讨论了氮化碳的形成机理。(c)2005爱思唯尔有限公司保留所有权利。
Carbon nitrides with graphite-like or onion-like lamellar structures were synthesized at low temperatures by the reactions of cyanuric chloride (C3N3Cl3) with NaNH2, K, or NaN3. The synthesized samples were investigated by powder X-ray diffraction, elemental analysis (from C-N combustion), X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, mass spectroscopy, field-emission scanning electron microscopy, transmission electron microscopy, and high-resolution electron microscopy. The synthesized carbon nitride with a graphite-like lamellar structure was obtained and observed for the first time. The formation mechanism of the carbon nitride was discussed.
