以无水C3N3Cl3和Li3N的苯溶液作为初始原料,在压力为5-6 MPa,温度为350℃条件下,利用溶剂热的合成方法成功地制备出了碳氮晶体.X射线粉末衍射(XRD)确定出样品中主要晶相成分为α-C3N4及β-C3N4,品格常数分别为a=0.650 nm,c=0.470 nm(α-C3N4);a:0.644 nm,c=0.246 nm(β-C3N4),这与第一性原理的理论计算值十分吻合.X射线能谱(XPS)以及Fourier变换红外光谱(FTIR)证明了碳氮是以C-N和C=N共价键的形式存在,氯碳元素的原子比为0.66.对溶剂热法制备氯化碳晶体材料的动力学问题进行了初步的理论探讨.
Carbonitride crystals were successfully prepared by a solvothermal method at a pressure of 5-6 MPa and a temperature of 350 ° C using the anhydrous benzene solution of anhydrous C3N3Cl3 and Li3N as raw materials.The results of X-ray powder diffraction (XRD) The main crystal components of the sample are α-C3N4 and β-C3N4. The lattice constants are a = 0.650 nm, c = 0.470 nm (α-C3N4) , Which is in good agreement with the theoretical calculation of the first principle.X-ray diffraction (XPS) and Fourier transform infrared spectroscopy (FTIR) proved that carbon and nitrogen are in the form of CN and C = N covalent bonds, Of the atomic ratio of 0.66. Solvothermal preparation of carbon chloride crystal material kinetics of a preliminary theoretical study.
