Abstract
Green synthesis methodology was used in this report to prepare the NiO nanoparticle for methylene blue (MB) dye photodegradation reaction. Various analytical performances were used to determine the physiochemical performance of the prepared NiO nanoparticle. The NiO nanoparticle has particle range of 20-30 nm with energy gap of 3.38 eV. The degradation efficiency against MB dye was evaluated and degradation under various environmental conditions were studied. The elemental scavenging test was conducted to understand the possible reaction mechanism for MB degradation reaction. As a result, we believe that this green synthesis NiO can open up new avenues for photocatalytic preparation and environmental remediation.
