Abstract

Co₃O₄ nanoparticles (NPs) were synthesized using Citrus lemon leaf extract, a novel green method. The synthesized NPs were extensively characterized using FTIR, UV-VIS, XRD, and SEM techniques, confirming their synthesis and properties. These NPs demonstrated promising catalytic efficiency (% degradation = 75.16 %), antioxidant potential (IC50 = 0.7 mg/ml), anti-biofilm activity (IC50 = 0.096 ± 0.005 mg/ml for E. coli, 0.08 ± 0.007 mg/ml for S. aureus) and antibacterial effects (ZOI = 28 mm for E. coli, 23 mm for S. aureus). This green synthesis method offers scalability and cost-effectiveness as compared to the energy-intensive and wasteful traditional methods. Our study exemplifies a commitment to advancing scientific progress through sustainable practices, contributing to global sustainable development goals.
