Abstract Herein, an effective photocatalyst involving titanium dioxide (TiO 2 ) on reduced graphene oxide (rGO), coated with conducting polymers, polyaniline (PANI), and polypyrrole (PPy) has been synthesized to investigate the adsorption kinetics photodegradation reaction employing 2,4‐dichlorophenoxyacetic acid (2,4‐D) a chlorophenoxy herbicide. The efficiency of as‐prepared catalyst, TiO ‐rGO‐PANI‐PPy studied against pristine , rGO, nanocomposites ‐rGO, ‐PANI‐PPy, ‐rGO‐PANI ‐rGO‐PPy under simulated sunlight. structural optical properties composite have validated through characterization by XRD, FTIR, Raman, FESEM, EDS, UV‐DRS BET surface area analysis. showed maximum in short time 30 minutes capacity (Q max 35.3 mg/g. Pseudo‐second‐order Freundlich isotherm models were effectively employed describe behavior 2,4‐D. exhibited significantly enhanced photocatalytic performance degradation 2,4‐D visible light irradiation compared pure or composites, ‐rGO‐PPy. Complete mineralization observed after 40 pH 7. was degraded fastest at strong acidic conditions. transformed intermediates identified HPLC‐MS/MS, possible pathway proposed.
