Abstract
In the current work, an efficient co-precipitation technique was used to develop a new Pr2O3/ZnO/g-C3N4 ternary nanocomposite. Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) were used for vibrational, structural, morphological, and compositional analysis, respectively. The FTIR spectrum confirmed the presence of characteristics vibrational bands associated with the Pr–O, Zn–O, at 603 cm−1 and 546 cm−1, respectively. The XRD pattern revealed the presence of diffraction peaks related to ZnO (hexagonal), Pr2O3 (hexagonal) and gC3N4 (tetragonal) in the nanocomposite. SEM images revealed that the nanocomposite has porous type morphology with high agglomeration. The photocatalytic activity of nanocomposite was assessed against organic dye pollutant Methylene blue (MB) and antibiotic Ciprofloxacin (CIP) under the sunlight irradiation. The maximum degradation efficiency of nanocomposite for MB 93% at pH = 11 and CIP 97% at pH = 6. The scavenger's experiment was carried out, and the findings demonstrate that the photocatalytic activity of MB and CIP is strongly dependent on the (•OH) and (O2•-) species. The antimicrobial activity was also analyzed against bacterial strains such as GrampositiveBacillus subtilis, Staphylococcus aureus, and Gram negative Klebsiella pneumoniae, Escherichia colispecies. The results showed higher inhibition zones against Escherichia coli.
期刊介绍:
International Journal of Environmental Research is a multidisciplinary journal concerned with all aspects of environment. In pursuit of these, environmentalist disciplines are invited to contribute their knowledge and experience. International Journal of Environmental Research publishes original research papers, research notes and reviews across the broad field of environment. These include but are not limited to environmental science, environmental engineering, environmental management and planning and environmental design, urban and regional landscape design and natural disaster management. Thus high quality research papers or reviews dealing with any aspect of environment are welcomed. Papers may be theoretical, interpretative or experimental.
