- Abstract
In recent years, nanotechnology has garnered significant attention and recognition due to its multifaceted contributions across diverse disciplines. Nano zinc oxide (ZnO) is a highly promising nano metal oxide that has found application in a wide range of areas, including fire retardancy, wrinkle reduction, and antimicrobial properties, among others. The wet chemical process was employed to synthesise nano zinc oxide, with Zinc nitrate hexahydrate as the precursor. The synthesised nano ZnO powder underwent characterization in order to determine its shape and physical properties. Four analytical techniques were utilised in this study. FTIR analysis was used to identify the functional group, X-Ray Diffraction was employed to determine the crystalline structure, SEMEDX Analysis was utilised to investigate the morphological structure and size of the synthesised nanoparticles as well as to confirm the presence of specific elements, and Transmission Electron Microscopy was employed to determine the size and shape of the synthesised nanoparticles. The synthesised nanoparticles of zinc oxide (ZnO) were employed for the purpose of photodegradation of a solution containing the Carbaryl insecticide. The experiment involved the utilisation of a set concentration of 5 ppm of Carbaryl pesticide. Additionally, a catalyst consisting of 5mg/L of nano ZnO was introduced. The resulting mixture was then subjected to photodegradation through exposure to UV irradiation. The degradation of the pesticide was shown to occur at a rate of 95% within a 60-minute timeframe. The results demonstrate the significant photocatalytic degradation activity exhibited by the nano ZnO particles that were synthesised.
