Degradation of Methyl Orangle by Magnetic Metal Doped TiO₂ Films in a Magnetic Field

Abstract:

In order to find an effective way to degrade the effluent, the Cu/TiO2, La/TiO2, Cr/TiO2 films with unique 3-D network structures were prepared using Ti(OBu)4 by sol-gel method loaded on the gauzes. These films structures were characterized by means of XRD and SEM. The effects of doped TiO2 films and combination of magnetic field and doped TiO2 films on the degradation of methyl orange (MO) were studied. The results indicated that after combinating the magnetic field, the photocatalysis efficiency of doped TiO2 films have been improved,especially the influence on Cu/TiO2 film was more obvious than other films.When magnetic intensity was around 30mT ,the MO degradation ratio went up to 60% by using Cu/TiO2 films.But the influences of magnetic intensity on photocatalytic activities of doped TiO2 films had a maximum value which was 30mT.
