Synthesis of Green Zno-Nps from Fruit Waste for Organic Waste Water Treatment by Photocatalysis

In the realm of nanotechnology, the environmentally conscious practice of using fruit waste and plants for synthesizing nanoparticles is increasingly captivating the attention of researchers. This approach, regarded as "Green Nanotechnology," offers an eco-friendly substitute for the conventional methods that involve the deployment of hazardous chemicals. The current study focuses on the fabrication of zinc oxide nanoparticles (ZnO-NPs) by utilizing a distinctive fruit waste and zinc sulfate as precursors, by sol-gel method. The resulting ZnO-NPs exhibit a hexagonal (wurtzite) shape and have been meticulously scrutinized and characterized through FTIR (Fourier Transform Infrared Spectroscopy) technique, then it was applied on a safranin o dye wastewater giving a promising degradation of 60% of initial concentration.
