In this research, ZnO doped Ni was immobilized over activated carbon nanoparticles, and the prepared photocatalysts were characterized by FTIR, XRD, SEM, EDS, and BET analyses and used for the degradation of reactive red 120 (RR120) dye under LED light irradiation. The C/ZnO-Ni photocatalyst demonstrated a flower-like morphology with mesoporous features. The effect of the main parameters like Zn:Ni molar ratio, photocatalyst amount, carbon mesh size, solution pH, initial RR120 concentration, H2O2 and power of LED lamp was investigated to maximize the efficiency of RR120 degradation. The best photocatalytic RR120 degradation of 94.88% was observed under the optimum conditions in which Zn:Ni molar ratio, photocatalyst amount, carbon mesh size, solution pH, initial RR120 concentration, H2O2 and power of LED lamp were adjusted at 1:2, 50 mg, 270, 3, 5 ppm, 0.2 mL and 50 W, respectively. Kinetic studies confirmed the applicability of the Langmuir-Hinshelwood theory by which the dye concentration is a first-order function of time. The reusability study of the C/ZnO-Ni photocatalyst showed good stability of the photocatalyst after recycling 7 times under the optimum conditions.
