Abstract
A simple, room-temperature process of using zinc oxide nanoparticles was established by reacting zinc nitrate hexahydrate and cyclohexylamine (CHA) in either aqueous or ethanol medium. Particles of polyhedra morphology were obtained for zinc oxide, prepared in EtOH (ZnO) and zinc 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 0.0166 ZnO nanoparticles wt %.
