  • Patent number: 8362094
    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 ethanolic medium. Particles of polyhedra morphology were obtained for zinc oxide, prepared in EtOH (ZnOE) and zinc oxide prepared in water (ZnOW). The results indicate that there are significant morphological differences between ZnOE and ZnOW. ZnOE showed a regular polyhedral shape, while spherical and chunky particles were observed for ZnOW. The morphology was crucial in enhancing the cyanide ion photocatalytic degradation efficiency of ZnOE by a factor of 1.5 in comparison to the efficiency of ZnOW at equivalent loading of 0.0166 ZnO nanoparticles wt %.
