Preparation of Cu-SiO2g-C3N4 Composite for the Removal of Pollutants from the Wastewater
(UMT, Lhr, 2023) HAFIZA HINA JAVED
In this work, copper-doped silica (Cu-SiO2)@g-C3N4 has been prepared to get a composite material. The composite material served as novel catalyst for the photocatalytic degradation (upto 99%) of a model dye methylene blue. In the presence of sunlight. In addition, the catalyst successfully inhibited some famous types of pathogens (E.Coli.and B. Subtilus) present in the polluted water. The composite material was characterized using various techniques for the surface morphology, stability and particle size. These analyses included spectroscopy, X-ray diffraction, scanning electron microscopy, and elemental analysis. The prepared composite material has the ability to reduce charge recombination and increase charge separation during the excitation in the presence of sunlight. The production of reactive oxygen species (ROS) at the surface of metal ions were thought to be responsible for the powerful antibacterial capabilities of the Cu-SiO2/g-C3N4 combination. These reactive species efficiently pierced the cell walls of the bacteria, which ultimately led to their extinction. Our results emphasize the strong antibacterial capabilities and extraordinary photocatalytic activity of the Cu-SiO2/g-C3N4 composite in degrading organic dyes, indicating its potential for a wide range of environmental and biological applications.
