Photo Catalytic Decomposition of Malachite Green in Aqueous Solutions under UV Irradition Using Nano ZnO Rod

Abstract

ZnO nano rod was prepared by microwave assisted method. The crystal structure of the nano powders were confirmed by X-Ray diffraction analysis and the mean particle size was estimated by the Scherrer's formula. The surface morphology of the nano particles were analyzed by SEM and TEM. The absorption spectrum of the material in the UV-Vis range was recorded. The prepared ZnO rod was used as a photocatalyst in presence of UV light against Malachite Green dye. The ZnO nanoparticle was found to be an efficient low cost photocatalyst which degraded Malachite Green dye in presence of UV light in a relatively short period of time.

“…This liquid was sonicated in an ultra-sonication bath for 30 min. The curdy white precipitate obtained was cooled at room temperature, filtered, and washed with water followed by drying in hot air oven at 100°C for 2 h. The main steps involved in the formation of ZnO are as follows (Rejani et al, 2014):…”
