Synthesis and Adsorption Properties of Nano Al2O3/TiO2 by Hydrothermal Method
Using auminum nitrate nonahydrate and titanium dioxide nanowires as the main raw material,Al2O3/TiO2 composite powers were prepared by the hydrothermal method at 200 ℃ for 24 hours.And the samples are characterized by XRD,nitrogen adsorption and desorption.The results show that the samples are corundum and rutile,and specific surface area is nearly 155 m2/g.Otherwise we tested samples for adsorption capacity of Congo red at different times,temperature and initial concentration under visible light irradiation.We found that it is the maximum adsorption efficiency (~107 mg/g) at the temperature of 50 ℃,within one hour to reach the adsorption saturation.
