Abstract

Abstract:

A ternary composite of TiO₂ and a SiO₂-Al₂O₃ aerogel with good photocatalytic activity was prepared by a simple sol-gel method with TiO₂ nanoparticles and SiO₂-Al₂O₃ aerogels derived from industrial fly ash. The structural features of the TiO₂/SiO₂-Al₂O₃ aerogel composite were investigated by X-ray powder diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, gas adsorption measurements and diffuse reflectance UV-visible spectroscopy. The optimal conditions for photocatalytic degradation of 2-sec-butyl-4,6-dinitrophenol (DNBP), included an initial DNBP concentration of 0.167 mmol/L at pH=4.86 with a catalyst concentration of 6 g/L, under visible light irradiation for 5 h. A plausible mechanism is proposed for the photocatalytic degradation of DNBP. Our composite showed higher photocatalytic activity for DNBP degradation than that of pure TiO₂. This indicates that this material can serve as an efficient photocatalyst for degradation of haz-ardous organic pollutants in wastewater.
