This study presents the green synthesis of the metal-organic framework/graphene quantum dot composite GQD/MIL101 using a simple method with water solvent. Composites were synthesized in different molar ratios of graphene quantum dots to MIL101, labeled as GQD/MIL101-5, GQD/MIL101-10, and GQD/MIL101-15, and assessed for photocatalytic activity. For the most effective composite (GQD/MIL101-15), key parameters such as pollutant concentration, initial pH of the solution, and photocatalyst dosage were optimized. The photocatalytic activity was assessed through the Photo-Fenton reaction using malachite green as the target pollutant, achieving an impressive degradation rate of approximately 99%. Scavenging experiments identified hydroxyl radicals as the most active and effective species participating. After six operational cycles, the photocatalyst showed remarkable recovery and stability, which emphasizes its potential for practical applications in wastewater treatment.
