| 摘 要： | 采用柱面飞管加载装置对双氰胺(C2N4H4)和镍粉混合物进行冲击加载,合成了一种高密度的氮化碳相(α-C3N4). 采用拉曼光谱(Raman)、红外光谱(IR)和透射电子显微镜(TEM)对回收样品进行成分、结构和形貌分析. 研究表明,冲击压力和温度是合成α-C3N4的重要条件,调整冲击温度,控制淬火速率,是生成α-C3N4的关键. 冲击压缩富氮的有机前体,为合成高密度的氮化碳相提供了一种新的途径.

| Abstract: | A α-C3N4 phase has been synthesized by shock loading on the mixtures of dicyandiamide (C2N4H4) precursor and nickel powder using a double cylindrical explosive compaction set-up. The component,structure and shape of the recovered samples were analyzed with Raman, Infrared spectra (IR) and transmission electron microscope (TEM). For the synthesis of α-C3N4 using the shock compaction, the pressure and temperature are two important factors, besides which the quenching rate plays a dominant role. The shock compression process may provide a novel synthesis route for various C-N phases from appropriate organic materials. |
