CdO孔材料的模板法制备及催化性能研究

Synthesis and characterization of CdO hollow materials and their catalytic properties

采用一步水热方法合成了C/CdS复合微球,经焙烧处理后得到CdO孔材料.使用电子扫描电镜、红外光谱、X射线粉末衍射等手段对C/CdS复合微球和CdO孔材料进行了表征,探讨了产品的形成机理,并研究了CdO作为火箭推进剂的燃速催化剂的性能.结果表明,CdO孔材料能使高氯酸铵高温分解温度降低67.65℃,具有很好的催化活性.

C/CdS composite microspheres have been synthesized by a simple hydrothermal process. After that, C/CdS composites are calcined to remove the carbon core, and CdO hollow materials are obtained. The samples are characterized by scanning electron microscopy （SEM）, FT IR spectra,and XRD patterns. The possible formation process of the C/CdS composite spheres and CdO are discussed. In addition, the catalytic properties of the CdO material are investigated.
