Abstract

The present study involves synthesis, characterization and application of ZnO nanoparticles for the photodegradation of phenol in wastewater. Zinc oxide nanoparticles were synthesized by sol-gel process calcination at 500 °C. The characterization was done by X-ray diffraction, scanning electron microscope and Brunauer-Emmet-Teller method to analyze the crystallite size, particle size, surface area. The crystallite size of ZnO nanoparticles was found to be comprised of 25-35 nm and the particle size was confirmed as 30 ± 5 nm with heterogeneous and spherical in shape. The photocatalytic activity of ZnO nanoparticles was evaluated using phenol as a model pollutant in UV and solar light. The photocatalytic experiments were carried out in a batch mode using 8 W UV lamp which emits a peak wavelength of 254 nm. The intensity of the sunlight during the reaction time was in the range of 808-1070 W/m2. Under optimum condition, ZnO nanoparticles showed higher degradation. A series of experiments were conducted to investigate the effect of concentration and effect of catalyst loading. The photocatalytic process follows pseudo first order kinetics. The addition of H2O2 leads to better enhancement for the degradation of organic contaminants in the presence of ZnO nanoparticles. The reusability of the ZnO nanoparticles has also been investigated.
