| Abstract | Water pollution is a critical global issue, hindering the achievement of SDG-6 on clean water and sanitation. Titanium dioxide (TiO?) nanoparticles (NPs) have emerged as effective photocatalysts for degrading organic pollutants. Green synthesis, utilizing plant-derived phytochemicals as natural reducing and capping agents, offers an eco-friendly alternative to conventional methods. This study reports the green synthesis of TiO? NPs using just (Syzygium cumini) leaf extract as a reductant. The synthesized nanoparticles were characterized using XRD, XRF, FTIR, UV-Vis, bandgap analysis, SEM, and TEM. The results confirmed the formation of anatase-phase TiO? with 98.21% purity (XRF), a spherical morphology (?10-50 nm), and a bandgap of 2.94 eV. Photocatalytic tests demonstrated 94.92% and 95.89% methylene blue degradation efficiencies after 180 and 240 minutes under UV light. These findings highlight the potential of green-synthesized TiO? NPs for environmental remediation. Future studies should explore modifications to enhance photocatalytic performance for wastewater treatment applications. |
