通过化学气相沉积法以SBA-15为模板成功制备出直径约为6nm的Cu3N纳米棒.分别采用X射线衍射(XRD)、电子透射显微镜(TEM)、EDS谱图及拉曼光谱对目的产物进行了分析和表征,证实模板SBA-15孔中生成了连续的Cu3N纳米线/棒,并沿模板孔道延伸有数百个纳米长.拉曼光谱对纯Cu3N及本实验目的产物SBA-Cu3N分析表明,因量子效应影响Cu3N纳米棒相对于纯Cu3N其特征分向小波数偏移,此峰可看作是Cu3N纳米棒所特有的特征.该制备二元氮化物纳米结构材料的方法操作简单、反应条件温和,并且可对产物尺寸进行控制,为其他二元氮化物纳米材料的制备提供了参考.
The Cu3N nanorods with a diameter of about 6nm were successfully prepared by chemical vapor deposition using SBA-15 as template.The target product was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), EDS and Raman spectroscopy Analysis and characterization confirmed that continuous Cu3N nanowires / rods were formed in the template SBA-15 well and hundreds of nanometers long along the template pore.Analysis of pure Cu3N and the target product SBA-Cu3N in this experiment by Raman spectroscopy , The characteristic shift of the wavelet number of Cu3N nanorods relative to that of pure Cu3N is affected by the quantum effect, and this peak can be regarded as a peculiar feature of the Cu3N nanorods. The method for preparing the binary nitride nanostructured materials is simple in operation and the reaction Mild conditions, and can control the size of the product for the preparation of other binary nitride nanomaterials provide a reference.
