  • Publication number: 20130168328
    Abstract: A simple, room-temperature method of producing CuO-doped zinc oxide nanoparticles was established by reacting zinc nitrate hexahydrate, copper nitrate trihydrate and cyclohexylamine (CHA) at room temperature. These nanoparticles may be used for photocatalytic degradation of cyanide in aqueous solutions. The degradation of cyanide is effective because electrons transfer from the p-type copper oxide to the n-type zinc oxide.
