Preparation and photocatalytic activity of silver and TiO2 nanoparticles/montmorillonite composites
Source abstract
Abstract
Abstract Ag–TiO2/montmorillonite (Ag–TiO2/MMT) was synthesized as photocatalyst using TiCl4 hydrolysis to introduce nanosized TiO2 into the interlayer space of the montmorillonite (MMT). Stable pillared TiO2/MMT was obtained by calcination at 500 °C, then silver was loaded by reduction of silver nitrate. The physico–chemical properties of the photocatalyst were determined by X-ray diffraction (XRD), infrared spectroscopy (IR), atomic absorption spectrophotometer (AAS), nitrogen gas adsorption (BET method) and UV–Visible spectra. The photooxidation activity for methylene blue (M.B.) degradation was as follows: Ag–TiO2/MMT > TiO2/MMT > TiO2(P25). Among them Ag–TiO2/MMT had the highest photooxidation activity because of its larger specific surface caused by pillaring and loading of silver for improving its light absorption.
