1D copper (II) based coordination polymer/PANI composite fabrication for enhanced photocatalytic activity

• New 1D Copper (II) based coordination polymer/PANI composite ( CP1/PANI ) was synthesized and characterized. • The CP1/PANI composite showed remarkable photocatalytic activity for the degradation of MB under UV light irradiation. • The synergistic effect between CP1 and PANI accelerated the photogenerated electron-hole pairs separation in the CP1/PANI composite. • CP1/PANI composite can be effectively used as a photocatalyst for organic dye degradation. One-dimensional Copper (II) Coordination polymer with pyridine-2-carboxylic acid ligand ( CP1 ) was loaded on PANI through in situ chemical oxidative polymerization of aniline to form 1 wt% , 2 wt% , 5 wt% , 10 wt% , and 12 wt% CP1/PANI composites and study their photcatalytic activities. The photocatalytic efficiencies of CP1 and CP1/PANI composite materials were studied for degradation of methylene blue (MB) under ultraviolet (UV) light irradiation. Results reveal that CP1/PANI composite materials exhibit higher photocatalytic performances in comparison with that of CP1 . The 10 wt %CP1/PANI composite exhibits the highest efficiency of about 88.31 % for the degradation in 210 min. The higher photocatalytic activity of CP1/PANI composite can be credited to the synergistic effect between CP1 and PANI that accelerates the separation efficiency of photogenerated electrons (e - ) and holes (h + ) at the interface between CP1 and PANI. Thus, CP1/PANI composites can be suitably used as an efficient photocatalysts for organic dye degradation.
