摘要

采用机械球磨法，以石墨为反应前驱物，在充有300 kPa压力的氨气气氛下连续球磨200 h，然后在氨气气氛、700℃以上的温度条件下热处理5h，制备出C3N4纳米棒。利用X射线粉末衍射(XRD)、透射电镜(TEM)、电子衍射、能量损失谱(EELS)以及红外光谱(FTIR)等手段进行了表征。纳米棒的长度在1～2 μm，直径为80～150 nm。分析结果表明合成的产物以β- C3N4单晶为主。对合成的β-C3N4产物进行光致发光(PL)性能测试和计算，得出其发射蜂在3.5～4.4eV之间，属于宽带隙的半导体材料。并对纳米棒的形成机理进行了初步探讨。

Abstract

Carbon nitride nanorods have been synthesized by ball milling method.The graphite powders were first milled for 200 h under the presence of the NH3 gas with 300 kPa.And then they were annealed for 5 h in the ammonia gas flow more than 700℃.The as-synthesized products were characterized by X-ray powder diffraction (XRD)，transmission electron microscopy (TEM)，electron diffraction (ED)，FTIR and electron energy loss spectroscopy (EELS).The diameter of nanorods is in the range of 80—150 nm and the length is about 1—2 μm.The results showed that the structure of the most as-synthesized products were β- C3N4 signal crystal.The optical property of β- C3N4 has been measured by the PL spectra and the computing results showed that the peak is at 3.5—4.4eV which confirmed that β- C3N4 is semi-conduct material with broad band.The growth mechanism of β- C3N4 nanorods is also discussed tentatively.
