N2 - A sustainable hydrothermal approach was adopted to synthesize nickel-doped SnO₂ nanocomposites (Ni/SnO₂ NCs) using the leaf extract of Matthiola incana as a natural reducing, stabilizing and capping agent. The Ni/SnO₂ NCs showed the impact of Ni inclusion on structural and optical properties with a lowered bandgap of 2.5 eV and a notable specific surface area of 134 m2 g−1. The as synthesized nanocomposite exhibited outstanding photocatalytic stability under visible light irradiation, achieving complete (100 %) degradation of methylene blue (MB) in 60 min while retaining 95 % efficiency after 3 reuse cycles. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) testing demonstrated excellent antioxidant potential with 88 % radical scavenging, while antibacterial activity showed inhibition zones of 28 ± 0.1 mm Escherichia coli ( E. coli ) and 25 ± 0.4 mm Staphylococcus aureus ( S. aureus ) under light exposure. These findings demonstrated the efficiency, recyclable properties, and scalability of M. incana -mediated Ni/SnO₂ NCs as a nanoscale material appropriate for wastewater purification, antimicrobial coatings, and green environmental remediation technologies.
