In this study, chitosan-based ZnO supported hydrogels (CZ–H) were synthesized to evaluate their photocatalytic degradation performance against methyl orange (MO) dye. The composite hydrogels were characterized using X-ray Diffraction (XRD), UV–Vis DRS, Scanning Electron Microscopy (SEM-EDS), Thermogravimetric Analysis (TGA), and Fourier Transform Infrared Spectroscopy (FTIR). These characterization results confirmed the successful formation of the CZ–H composite structure. The band gap of the composite was approximately 2.77 eV, supporting enhanced photocatalytic activity. Photocatalytic experiments showed that CZ–H removed 74% of MO within 60 min, compared to 42% for pure chitosan beads, with reaction rate constants of 0.0237 min−1 and 0.0113 min−1, respectively. Moreover, the CZ–H beads demonstrated good reusability with minimal loss in efficiency over multiple cycles. These findings highlight the potential of CZ–H as a stable, effective, and reusable photocatalyst for the efficient removal of dyes from wastewater.
