Superior photocatalytic activity of polypyrrole nanostructures prepared by radiolysis in water and dichloromethane

Conjugated polymers have emerged as very active photocatalysts under visible light. Among these materials, nanostructured polypyrrole (PPy) has recently been used photocatalyst for degradation of environmental pollutants UV well In the present study, we specifically explored photocatalytic activity conducting PPy synthesized by radiolysis, either in water (PPy H2O ) or dichloromethane solvent DCM ), absence any external dopant template. The successful preparation both kinds was confirmed complementary spectroscopic techniques and morphological characterizations. Besides, materials evaluated phenol model pollutant aqueous solution. were found to exhibit remarkably high These organic remain stable after several cycles thus, easily reusable. Interestingly, clearly appears most efficient due its longer chain length, highly doped nature, lower optical band gap extended absorption from near infrared region. work definitely validates radiation chemistry an alternative approach synthesize polymer-based photocatalysts. obtained results also highlight that radiosynthesized PPy, especially those prepared dichloromethane, constitute promising candidates depollution water. • Radiolysis is synthesis DCM. produced a doping state with low intense absorption. are Vis Photocatalytic much greater than . one best based
