Abstract

The characteristics of the UV illumination-assisted degradation of Malachite green (MG) on highly active nanostructured-anatase TiO2, bulk Polyaniline (PAni), PAni nanoparticles and PAni-TiO2 nanocomposites have been studied. Dodecylbenzene sulphonic acid doped PAni-TiO2 nanocomposites were synthesized by a water-assisted self-assembly method. Samples were characterized using transmission electron microscopy, X-ray diffraction studies, Fourier Transform Infra red spectroscopy and photoluminescence studies. Photoluminescence intensity of TiO2 nanoparticles was found to decrease with the increase of PAni in the nanocomposite which can be attributed to the reduction of electron-hole pair recombination at the interface of PAni and TiO2 due to electron transfer from TiO2 to PAni. Exposure to UV light brought about the photocatalytic oxidation of MG in contact with bulk PAni, PAni and TiO2 nanoparticles, and PAni-TiO2 nanocomposites. The decrease in absorbance was measured, and its kinetics was analyzed using the Langmuir-Hinshelwood kinetic model. PAni-TiO2 nanocomposites exhibit higher photocatalytic activity than pure TiO2 nanoparticles, bulk PAni and PAni nanoparticles under the same degradation condition for MG. The enhanced photocatalytic activity of nanocomposites is attributed to the electron transfer from TiO2 to PAni resulting in enhancing the oxidative property of the TiO2 nanoparticles.
