Abstract
Escalating water pollution necessitates the development of efficient and sustainable photocatalytic materials for the degradation of organic pollutants. In this work, the photocatalytic properties of carbon-doped zinc oxide (C-ZnO) nanoparticles synthesized by a novel mechanochemical method are investigated. The unique approach of doping ZnO nanoparticles with carbon not only increases the absorption of visible light but also improves the efficiency of charge separation, leading to a significant increase in photocatalytic activity. Experimental analytical methods such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis spectroscopy are used to elucidate the structural, morphological, and photocatalytic properties of the synthesized C-ZnO nanoparticles. The photocatalytic performance of C-ZnO nanoparticles is evaluated by their ability to degrade methyl orange at a concentration of 5 ppm under UV light irradiation with and without mixing the solution for 60 minutes in the dark before exposure to UV light. The influence of the photocatalysis time on the degradation efficiency was investigated. The results show that the photocatalysis time has a strong influence on the degradation efficiency.
