Abstract

For the last few decades, photocatalysis has attracted as an emerging successful technology for purifying wastewater by dye degradation from households and industries. TiO2-based photocatalysis has gained wide attention due to its importance in energy source as well as its outstanding involvement in the reduction in environmental problems. Consequently, researchers and scientists are looking for the synthesis of polyaniline-TiO2-based photocatalysts which are widely being used for the degradation of dyes. Lately, the use of polyaniline as photosensitizers has proved that it immensely enhances photodegradation by its excellent photocatalytic activity under both ultraviolet light and natural sunlight irradiation. Considering this most unique performance of Polyaniline-TiO2-based photocatalysis, the present review provides the recent advances and trends in the development of ultraviolet and visible light-responsive polyaniline-TiO2-based photocatalysis for their potential application in environmental remediation by dye degradation.
