Abstract 

Visible light active photocatalysts are much sought after due to possibility of development of efficient and less expensive photoreactors for environmental applications. We prepared a visible light active photocatalyst, polyaniline-TiO2 (PANI-TiO2) nanocomposite, using insitu polymerisation method. It was characterized using photocatalytic activity of the PANI-TiO2 nanocomposite was tested for photo degradation of Reactive Blue 4 (RB- 4) using visible (100 W tungsten-halogen lamp) as well as UV lamp (125 W). The PANI/TiO2 nanocomposites having thin layers of PANI (~1 nm) polymerized on the surface of TiO2 nanoparticles (~30 nm) were obtained. The nanocomposite displayed remarkable photocatalytic activity under visible light irradiation (% RB-4 removal efficiency ³ 92; % TOC removal ³ 50). About 15 times greater rate constant for the reaction under visible light (5.23 × 10-2 min-1) was obtained compared to the rate constant with TiO2 (k = 3.5 ´ 10-3 min-1). The kinetic and morphological data were discussed in the light of the reported data for PANI/TiO2 materials produced earlier by different methods. On the basis of such comparison, a PANI/TiO2 in which TiO2nanoparticles are deposited on polyaniline could be inferred to have higher photo activity over the other forms.
