Abstract
TiO2-halloysite (TiO2-HNT) composites were fabricated by depositing anatase TiO2 on the halloysite (HNT) surfaces with calcination treatment at 100, 200, 300 and 500 ℃. The obtained composites were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and X-Ray diffraction (XRD). HNT was attached with TiO2 particles or clusters in sizes of 10-30 nm. With the increasing of calcination temperature, the crystalline of anatase became more perfect, but the structure of HNT could be destroyed at 500 ℃. The adsorption and photodegradation of methylene blue (MB) by TiO2-HNTs were investigated. The kinetic adsorption fit the pseudo second-order, and the isotherm data followed the Langmuir model. The maximum adsorption capacities of MB were in the range of 38.57 to 54.29 mg/g. TiO2-HNTs exhibited an efficient photocatalytic activity in the decomposition of MB. For TiO2-HNT calcined at 300 ℃, 81.6% MB were degraded after 4 h treatment of UV irradiation.
