This study presents ascorbic acid/MIL-100 (Fe) bio-hybrid, prepared via an environmentally friendly green synthesis method at room temperature, providing a sustainable approach to develop an efficient photocatalyst for environmental remediation. The structural and morphological properties of the synthesized bio-hybrid were confirmed by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray spectroscopy with elemental mapping and Thermo gravimetry. Under visible light irradiation, 0.04 g/L of the bio-hybrid degraded around 90% of the acid blue 92 solution, 80 mg/L in the presence of hydrogen peroxide. The electron-donating properties of ascorbic acid and the characteristics of the metal-organic frameworks resulted in a synergistic effect and remarkable performance for this hybrid. The degradation reaction followed first-order kinetics and was driven by hydroxyl radicals as the most effective active species. Excellent stability and reusability over four cycles, cost-effectiveness, and demonstrate the hybrid's potential for long-term wastewater treatment. This nature-inspired material promises broader pollutant removal using biomaterials, offering sustainable solutions for water purification and environmental protection.
