Photo Catalytic Properties of Fe-modified and Magnetic Nano-titanium Prepared by Hydrothermal Method
In order to improve the separation efficiency and the circular utilization ratio of the catalyst,the Fe-doped nano-titanium and nano-titanium supported on Fe2O3 carrier was prepared by hydrothermal method.The tetra-butyl titanate and ethanol were used as starting materials to prepare nano-titanium.The results of Fe-doped nano-titanium showed that the doping of iron changed the nano-titanium crystal and crystal morphology.No matter UV-light or mercury lamp 577 nm irradiation,the samples with 0.5 mM Fe addition showed the highest photo catalytic activity,with degradation rate of methyl blue above 95%.The structure,photo catalytic activity and magnetic properties analysis showed that the magnetic nano-titanium met the purpose of separation between the catalyst and reaction solution.The photo catalytic activity of nano-titanium supported on Fe2O3 carrier has respond to visible light.With mercury lamp 577 nm as irradiation source,degradation rate of methylene blue light could reach 63.40%.
