Abstract:
Nanocomposites composed of zinc oxide (ZnO) have attracted a lot of attention due to their ability to remove the pharmaceutical pollutants that don't break down in the environment. In this study, ZnO-25 wt% CNT nanocomposite were synthesized and studies to find out its structure, optics, and photocatalytic properties. XRD confirmed that ZnO was in a crystalline phase with nanoscale crystallite size and that the CNTs were well integrated into the matrix. UV-visible spectroscopy revealed a strong absorption edge in UV region, with the optical band gap estimated at approximately 3.12 eV, which is lower than that of pure ZnO, suggesting improved light-harvesting capacity. The photocatalytic activity has been evaluated through the decomposition of methylene blue (MB) dye while under UV irradiation. The composite had a remarkable ~85% degradation efficiency for this nanocomposite. The better performance is due to the efficient separation of charge carriers and the increased mobility of electrons that come from adding CNT. These results show that ZnO-CNT nanocomposites could be very useful and cheap photocatalysts for treating wastewater.
