Industrial waste, agricultural residues, and urban waste have become significant issues concerning water pollution and its permissible remediation solutions. Organosynthetically-accessible conducting polymers (CPs) like polyaniline (PANI), polypyrrole (PPy), and poly(3,4-ethylenedioxythiophene) (PEDOT) have shown immense potential in photocatalytic water treatment due to their optical activity, electrical properties, and physicochemical characteristics. These polymers are solution-processable, biocompatible, and can be effectively incorporated into hybrid semiconductor nanocomposites with inorganic materials, including titanium dioxide (TiO2), to improve visible light absorption and reduce the recombination of photogenerated charge carriers. This chapter discusses recent developments in polymer-based photocatalysts, synthesis strategies, optoelectronic properties, and pollutant degradation mechanisms. These materials’ applications, challenges, and future directions in global environmental remediation are also critically assessed.

摘要

Industrial waste, agricultural residues, and urban waste have become significant issues concerning water pollution and its permissible remediation solutions. Organosynthetically-accessible conducting polymers (CPs) like polyaniline (PANI), polypyrrole (PPy), and poly(3,4-ethylenedioxythiophene) (PEDOT) have shown immense potential in photocatalytic water treatment due to their optical activity, electrical properties, and physicochemical characteristics. These polymers are solution-processable, biocompatible, and can be effectively incorporated into hybrid semiconductor nanocomposites with inorganic materials, including titanium dioxide (TiO2), to improve visible light absorption and reduce the recombination of photogenerated charge carriers. This chapter discusses recent developments in polymer-based photocatalysts, synthesis strategies, optoelectronic properties, and pollutant degradation mechanisms. These materials’ applications, challenges, and future directions in global environmental remediation are also critically assessed.
