多壁碳纳米管/氧化亚铜的制备及其对N-甲酰吗啉的光催化性能
|
摘要
采用液相还原法制备多壁碳纳米管/氧化亚铜(MWCNTs/Cu2O)复合微球。利用傅立叶变换红外光谱仪(IR)、扫描电子显微镜(SEM)、X射线衍射仪(XRD)等对样品进行官能团分析、物相分析和形貌观察,结果表明:多壁碳纳米管以纵横穿插方式与氧化亚铜形成复合微球。对比氧化亚铜和多壁碳纳米管/氧化亚铜对目标有机物N-甲酰吗啉的光催化活性,结果表明:多壁碳纳米管/氧化亚铜复合催化剂的催化效果明显优于氧化亚铜。
Multi-walled carbon nanotubes/cuprous oxide(MWCNTs/Cu2 O)composite microspheres were fabricated by liquid phase reducing method.The analycis of the functional group,phase and morphology on the samples were characterized by fourier transform infrared spectrometer(FTIR),scanning electron microscope(SEM)and x-ray diffractometer(XRD),which indicated that MWCNTs were combined with Cu2 O to form composite microspheres by vertical and horizontal interspersing.The results showed that compared with the photocatalytic activity of the Cu2 O,the MWCNTs/Cu2 O composite catalyst has more excellent catalytic effect on target organic compound N-formylmorpholine.
