Polythiophene (PTh) and its nanocomposites are considered promising photocatalytic candidates due to their unique electrical behavior, good environmental stability, low optical band gap, and ease of synthesis. The fabrication of metal oxides with PTh extends the absorption range and enhances photocatalytic activity under various light sources. Studies focus on the performance, preparation, and degradation mechanism of pollutants by PTh and its nanocomposites under different irradiation conditions.
Polythiophene (PTh) and its nanocomposites are considered as promising photocatalytic candidates due to their unique electrical behavior, good environmental stability, low optical band gap, stability in doped/ neutral states and in particular the ease of synthesis. Apart from electrical and electronic applications, PTh has shown remarkable performance in photocatalysis. The fabrication of metal oxides with PTh extends the absorption range of PTh-based composite materials, which enhances the photocatalytic activity under UV/UV-visible light irradiation as well as under microwave exposure. PTh-based composites with metals/ metal oxides exhibit synergistic photocatalytic properties. The present review therefore highlights the studies dealing with the photocatalytic performance of PTh and its nanocomposites along with their preparation, properties and mechanism of degradation of various kinds of pollutants under UV, visible light, sunlight and microwave irradiation.
