Thermally tuned green-synthesized NiO nanostructures exhibiting enhanced crystallinity, band gap narrowing, and superior photocatalytic activity toward organic dye degradation

The green synthesis of photocatalytic materials provides a sustainable strategy for environmental remediation. In this study, nickel oxide (NiO) nanoparticles were synthesized using Johrenia aromatica fruit extract as a natural phytochemical-mediated agent, followed by calcination at 500, 600, and 700 °C. Structural ch...
