The presence of antibiotics and dyes as organic contaminants has caused severe wastewater pollution, posing a significant environmental concern globally. To address this issue, this study highlights the green synthesis of ZnO/Ag₂CO₃ nanocomposites using bael gum (BG) for the photocatalytic degradation of norfloxacin (NOF) and Amido Black 10B (AB 10B), along with their antimicrobial activity. The synthesized BG-ZnO/Ag₂CO₃ nanocomposites were extensively characterized for their optical, structural, morphological, chemical purity, crystal structure, and surface area properties using XPS, XRD, FT-IR, FESEM, EDS, photoluminescence (PL) spectra, Raman analysis, HR-TEM, BET, and LC-MS. The nanocomposites materials exhibited excellent photocatalytic performance under visible light irradiation, achieving the degradation efficiencies of 91.03 % for AB 10B and 81.5 % for NOF,with corresponding rate constants of 0.017 min
