Abstract
l-Histidine–MgO–AgI composites were produced by varying MgO and AgI content from 1 to 10 wt%. FTIR, UV-vis, photoluminescence (PL), and EDX data confirmed successful incorporation of MgO and AgI into l-histidine. FESEM analysis revealed a transition from relatively uniform sheet-like structures in pristine l-histidine (50–600 nm) to irregular, aggregated sheet-like morphologies in the l-histidine–MgO–AgI composites (50–800 nm). XRD analysis revealed an average crystallite size of 33.12 nm for the composites. Thermogravimetric analysis (TGA) indicated enhanced thermal stability of the composites. The composite containing 10 wt% MgO and AgI achieved the highest degradation efficiencies of 68.86% and 67.04% under sunlight and UV-lamp irradiation, respectively. HPLC analysis verified the efficient photocatalytic degradation of TC, while TOC analysis revealed a mineralization efficiency of 38.23%. The photocatalyst retained 64.19% degradation efficiency after three cycles. LC-MS analysis identified the degradation intermediates of TC. These results emphasize the potential of l-histidine–MgO–AgI composites for efficient photocatalytic removal of TC.
