The development of industries leads to different types of pollution which affects both environment and human health. Of these, water pollution is considered as the most serious issue, which leads to the scarcity of potable water around the world. Among these pollutants, 70% of the effluents are from the dyeing process in the textile industries. In recent years the photocatalytic degradation of dye has got more attention since it is a greener way to tackle the problem. Dye degradation using photocatalyst can be improved by expanding the area of light absorption using conductive polymers and also by increasing the photogenerated electrons. In this aspect, we were able to successfully produce photocatalyst by the in-situ polymerization of aniline in the presence of TiO2 with ammonium peroxydisulfate as an oxidising agent. The successful formation of PANI-TiO2 nanocomposites was verified through the utilisation of X-Ray Diffraction (XRD) and Fourier Transform Infrared spectroscopy (FTIR) and the degradation of the basic dye malachite green is studied in the presence of PANI-TiO2 nanocomposite which shows that almost complete degradation of 97% occurs under the tungsten lamp when 10−5 M concentration of dye was used.
