Abstract: Photocatalysis using semiconductor Zinc Oxide (ZnO) is a promising technology for water purification. The current work is aimed at improving the reduction of organic carbon of domestic wastewater by a combination of photocatalysis and Green synthesis. Synthesized zinc oxide nanoparticles from Plectranthus amboinicus was characterized by UV spectroscopy, FTIR, SEM, and XRD. Degradation of organic matter in effluent using Zinc Oxide and Plectranthus amboinicus was examined by the photocatalytic reaction. The reduction of organic carbon was analyzed by COD and pH analysis on synthesized ZnO nanoparticles. The decrease in COD from 800 mg/l to 50 mg/l and an increase in pH from 6.8 to 7.4 results in degradation of organic matter in the effluent. These advantages enable us to reuse the treated water for various purposes such as flushing, gardening, cleaning.
