摘要:
在相对温和的条件下通过溶剂热合成法制备了新型磁性层次复合碳质纳米微球材料,通过透射电镜(TEM)和扫描电镜(SEM)表征了其表面形貌、颗粒大小和微观结构。利用N2吸附-脱附仪表征了其孔道结构,利用傅里叶变换红外(FT-IR)光谱仪表征了微球表面的官能团,通过X-射线荧光光谱仪表征了其元素含量。表征结果表明,所合成的磁性碳质纳米材料具有层次复合结构特点,表面有大量的羧基官能团并成功负载纳米金属Zn2+。实验结果表明,合成的磁性层次复合碳质纳米材料具有优异的光催化降解有机物的性能,并具有良好的磁分离和重复利用性能。
Abstract:
A new type of magnetic hierarchical carbonaceous sphere with nano-sized was prepared by hydrothermal synthesis under relatively mild conditions, and comprehensive investigation of the synthetic route was carried out in detail. The micro-structure such as surface morphology, particle size of the synthesized magnetic carbonaceous nanospheres were characterized by transmission electron microscopy(TEM)and scanning electron microscopy(SEM). The porous structure of magnetic carbonaceous nanomaterials was also characterized through the N2 adsorption-desorption isotherms. The functional groups on the surface of the magnetic hierarchical carbonaceous sphere were characterized by Fourier transform infrared(FT-IR)and X-ray fluorescence spectrometer(XRF). The characterization results show that the synthesized magnetic hierarchical carbonaceous sphere has typical hierarchical structure, and a large number of carboxyl functional groups on the surface which is available for nano-sized Zn2+ loading. The photocatalytic results show that the synthesized magnetic carbonaceous materials have excellent photocatalytic degradation of organic matter. And the magnetic hierarchical carbonaceous spheres also have excellent recyclability under magnetic field.
