Abstract Crystalline carbon nitride (C3N4) has been synthesized by a simple pyrolysis assisted chemical vapor deposition (CVD) method using Triazine (C9H18N6) as a precursor. Analysis of the x-ray diffractogram shows that the synthesized powder has lattice parameters a = 6.27 A, c= 2.37 A and c/a= 0.378; consistent with the β- C3N4 crystalline structure. Microstructure analysis showed that the powder comprised of nanostructures with sheet and/or tubular structures. Spectroscopic analysis confirmed the presence of nitrogen in the prepared material and formation of the carbon nitride phase. X-ray photoelectron spectroscopy analysis shows presence of sp3 C-N bonds in the powder. D and G bands observed in the Raman spectrum show a red-shift when nitrogen is introduced in the carbon network. Besides, the presence of nitrogen in the carbon network has also been quantified using EDS and XPS. The present study suggests that the pyrolytic synthesis technique utilizing the CVD is one of the promising techniques to prepare β-C3N4 structure.

用简单的 CVD-热解法合成 β 氮化碳纳米结构

摘要 使用三嗪 (C9H18N6) 作为前驱体，通过简单的热解辅助化学气相沉积 (CVD) 方法合成了结晶氮化碳 (C3N4)。X射线衍射图分析表明，合成粉末的晶格参数a=6.27A，c=2.37A和c/a=0.378；与β-C3N4 晶体结构一致。微观结构分析表明粉末由具有片状和/或管状结构的纳米结构组成。光谱分析证实在制备的材料中存在氮并形成氮化碳相。X 射线光电子能谱分析表明粉末中存在 sp3 CN 键。当碳网络中引入氮时，在拉曼光谱中观察到的 D 和 G 带显示红移。除了，碳网络中氮的存在也已使用 EDS 和 XPS 进行量化。目前的研究表明，利用 CVD 的热解合成技术是制备 β-C3N4 结构的有前途的技术之一。
