Effect of aqueous matrix species on synergistic removal of bisphenol-A under solar irradiation using nitrogen-doped TiO2/AC composite

▶ A bi-functional composite, namely N-TiO2/AC was synthesized via sol-gel method. ▶ Provision of activated carbon support abated the detrimental effects of SO42−. ▶ Addition of 0.01-0.1 mM H2PO4− enhanced bisphenol-A photodegradation efficiency. ▶ Addition of C2O42− revealed that bisphenol-A could also be photodegraded by holes.
