Conductive polymers (CPs) play a crucial role in enhancing photocatalysis through various mechanisms. By improving charge carrier separation, expanding light absorption, increasing reactant adsorption, inhibiting photocorrosion, and reducing the formation of large aggregates, CPs elevate the overall effectiveness of photocatalytic reactions. Alfa Chemistry Catalysts offers a range of CPs like polyaniline (PANI), polyacetylene (PA), and polythiophene (PTh) that enhance photocatalytic activity. Applications of conductive polymers in composite photocatalysts have shown promising results in fields such as degradation of hazardous chemicals, antibacterials, photocatalytic hydrogen production, and water treatment. Polyaniline and its composites are frequently used in the photocatalysis of environmental pollutants, with dyes being a common target for CP photocatalytic testing. Moreover, the article highlights the role of conductive polymers like PANI, PPy, and PEDOT in enhancing photocatalytic hydrogen production. For instance, the combination of PANI and CdS in core-shell nanorods has shown increased hydrogen yield due to improved injection of photoexcited holes. Research studies, like those by Chao Wang, emphasize the importance of conductive polymers in improving photocatalytic processes. In conclusion, the integration of conducting polymers with semiconductor materials demonstrates significant potential for advancing photocatalytic applications, offering solutions for environmental remediation and sustainable energy production.
