摘要

摘要 本文采用水热合成法制备了基于碳纳米管的磁性纳米复合光催化剂,其表面包覆有铁氧体钴和氧化锌。然后,利用 X 射线衍射、扫描电子显微镜、振动样品磁力计和可见光-紫外光谱分析(UV-Vis)等多种技术对其物理和化学性质进行了研究。下一步是研究制备的光催化剂在可见光下去除有毒染料的光催化活性。为此,在特定的实验条件下,有毒染料在光催化剂和可见光的存在下被去除。结果发现,在可见光下需要较长的时间,但在紫外线分析下,它们在 60 分钟内就会降解。然后,利用紫外电子吸收光谱等技术测量了染料的去除程度。结果表明,基于碳纳米管、涂覆有铁氧体钴和氧化锌的磁性纳米复合光催化剂在可见光下具有很高的去除有毒染料的光催化活性。研究结果还表明,在碳纳米管上涂覆钴铁氧体可显著提高光催化活性,增加钴铁氧体的用量可大大提高去除有毒染料的效果。此外,所制备光催化剂的磁性使其在使用后易于回收。

Fabrication of Magnetic Nanocomposite Photocatalysts Based on Coated Carbon Nanotube for Removing Toxic Dyes

In this article, magnetic nanocomposite photocatalysts based on carbon nanotubes, coated with cobalt ferrite and zinc oxide were prepared using hydrothermal synthesis method. Then, their physical and chemical properties have been investigated using various techniques such as X-ray diffraction, scanning electron microscope, vibrating sample magnetometer and visible-ultraviolet spectroscopic analysis (UV-Vis). In the next step, the photocatalytic activity of the prepared photocatalysts for the removal of toxic dyes under visible light has been investigated. For this purpose, toxic dyes have been removed in the presence of photocatalyst and visible light under specific experimental conditions. It was found that under visible light, longer time is required, but under UV analysis, they degrade within 60 min. Then, using techniques such as UV electron absorption spectroscopy, the extent of dye removal has been measured. The results show that the magnetic nanocomposite photocatalysts based on carbon nanotubes, coated with cobalt ferrite and zinc oxide have high photocatalytic activity for the removal of toxic dyes under visible light. Also, the results show that coating the carbon nanotube with cobalt ferrite has a significant improvement in photocatalytic activity and increasing the amount of cobalt ferrite shows a substantial perfection in the removal of toxic dyes. Also, the magnetic nature of the prepared photocatalysts allows their easy recovery after use.
