Stable TiO2/rectorite: Preparation, characterization and photocatalytic activity
Abstract Stable TiO2/rectorite (TR) was prepared by intercalating colloidal titania particles into rectorite at low temperature (70°C). The TR samples were characterized by XRD, HRTEM, N2 adsorption–desorption, FT-IR and UV–vis DRS. The specific surface area of the TR could be increased to 219m2/g. TR showed an efficient photocatalytic activity in the decomposition of the anionic dye acid red G (ARG) by UV light irradiation. The photocatalytic activity was fully maintained after five photocatalytic cycles, which could be attributed to the porous structure and the large specific surface area of TR.
Research Highlights ► The photocatalyst (TiO2/rectorite) was prepared at low temperature. ► The specific surface area of the TiO2/rectorite was larger than that of rectorite. ► The photocatalyst shows excellent photocatalytic activity under UV light irradiation. ► The photocatalyst remained stable after five photocatalytic degradation cycles.
