Activated carbon (AC) loaded nitrogen and sulfur (N, S) co-doped TiO2 &ensp nanomaterial (AC-N-STiO2) was prepared by precipitation method. AC-N-S-TiO2&enspmaterial was characterized by Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray analysis (EDX), X-ray diffraction (XRD), Fourier Transform - Infrared (FT-IR), Photoluminescence (PL) and atomic force microscopy (AFM) analysis. Photodegradation and decolorization of Malachite green (MAG) and Methyl green (MEG) by using TiO2,N-S-TiO2 &enspand AC-N-S-TiO2under UV-light irradiation has been carried out. The photocatalytic activity of the AC-N-S-TiO2&enspwas higher than that of the undoped and N, S-doped TiO2,The hydroxyl radical analysis - Fluorescence technique with coumarin has been discussed. The photodegradation of MEG was well described by analyzed to be pseudo-first order according to the Langmuir-Hinshelwood representation, the high quantum yield set up to be calculated, stability and reustability of nanomaterial. AC-N-S-TiO2 &enspact as a promising photocatalyst for dye wastewater treatment under UV-light irradiation.
