Environmental problems caused by the influence of organic dyes have devoted researchers to build the system for the degradation of dyes. Photocatalysis has gained a remarkable interest to degrade organic dyes for wastewater treatments. In this work Polyaniline@NiO with different wt.% the composition was synthesized with rich catalytic sites by in‐situ polymerization to degrade the organic dye Rhodamine‐B from water. The synthesized materials were characterized by XRD, RAMAN spectroscopy, SEM, UV/Vis spectroscopy and Photocatalytic degradation. Polyaniline (PANI) showed a high absorption coefficient in visible light and NiO absorbs light in the ultraviolet range. The charge mobility was enhanced by making a composite of PANI and NiO. The photocatalytic performance of PANI in visible light was improved by making its composite with NiO, which provides the easing path to flow photoelectron from LUMO of PANI to the surface of the water and further dye degradation mechanism was performed [ABSTRACT FROM AUTHOR]
