The photodegradation of malachite green in water was successfully achieved under LED irradiation in the presence of NiO/zeolite photocatalyst. The photocatalyst was prepared by the impregnation method and characterized by XRD, BET, FTIR, DRs, and SEM techniques. The experiments were investigated by varying factors that influence the malachite green removal, such as adsorption, initial dye concentration, catalyst dose, and pH. The characterization results show that the material exhibited a direct optical transition (1.45 eV). The results indicated that NiO/zeolite shows a synergic effect between adsorption/photocatalysis processes.
