Abstract
TiO2P-25 and montmorillonite (MMT) nanocomposite films were deposited on stainless steel substrates using electrophoretic deposition (EPD) of suspensions with various ratios of TiO2: MMT (TM). The deposited films were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive Xray spectra (EDX) analyses. The photocatalytic activity of the nanocomposite films for adsorptive removal of methylene blue (MB) pollutant in aqueous solution were studied in dark environment and under UV irradiation, respectively. The maximum adsorptive removal of 79% is achieved for a TM1:1 ratio after 120 minutes. The photocatalytic activities of MB on the films follows the order of TM2:1 (84%) > TM1:1 (81%) > TM5:1 (68%) > TM10:1 (59%) > TM20:1 (45%) > pure TiO2 (38%). The kinetic study by Langmuir-Hinshelwood mechanism shows the highest photocatalytic decolorization rate with a ratio of TM10:1.
