Abstract
A simple, room-temperature method of producing zinc oxide nanoparticles was established by reacting zinc nitrate hexahydrate and cyclohexylamine (CHA) in either aqueous or EtOHic medium. Particles of polyhedra morphology were obtained for zinc oxide, prepared in EtOH (ZnO), while an irregular spherical morphology, mixed with some chunky particles forzinc oxide prepared in water (ZnO). The results indicate that there are significant morphological differences between ZnOand ZnO. ZnOshowed a regular polyhedral shape, while spherical and chunky particles were observed for ZnO. The morphology was crucial in enhancing the cyanide ion photocatalytic degradation efficiency of ZnOby a factor of 1.5 in comparison to the efficiency of ZnOat equivalent loading of 0.02 ZnO nanoparticles wt %. Increasing the loading wt % of ZnOfrom 0.01 to 0.07 led to an increase in the photocatalytic degradation efficiency from 67% to 90% after 45 minutes and a doubling of the first-order rate constant (k).
