Many applications consider Polypyrrole (PPy) one of the most prominent conductive polymers due to its distinguished character, low cost, and easy preparation. Recently, organic polymeric conductors have seen an upsurge in photocatalysts for energy conversion, and air/water depollution under either UV and/or visible light illumination. We present a comprehensive review of related papers for PPy in water/air pollutant photo -degradation, CO2 reduction reaction (CO2 RR), or evolution of hydrogen from water dissociation (WSP) under simulated sunlight irradiation, mainly in the last ten years. Besides, some of the current applications for PPy as pure or a portion of composite material are also included briefly. This review also includes the synthesis stra-tegies, polymerization process parameters, modification methods, photocatalytic activity, and challenges that face PPy-based materials. Above and over, the main difficulties and prospects of using PPy-based photocatalytic material in the perspective application have also been mentioned.
