ABSTRACT This study investigates the sustainable synthesis and applications of α‐Fe₂O₃@ZnO nanocomposites derived using Laurus nobilis leaf extract as a natural reducing agent, promoting eco‐friendly material development for environmental remediation. XRD analysis confirmed formation nanocomposite with crystallite size 21.48 nm, while SEM revealed porous structure uniformly distributed particles ranging from 20 to 50 nm. FTIR spectroscopy identified characteristic Fe‐O Zn‐O bonds, ensuring nanocomposite's purity. Optical showed direct indirect bandgap energies 2.80 1.16 eV, respectively, highlighting its excellent optical properties. The demonstrated remarkable photocatalytic efficiency, achieving 96.3% degradation Brilliant Cresyl Blue (BCB) dye 95.88% Rose Bengal (RB) within 120 min under sunlight irradiation. followed first‐order kinetics, rate constants 0.0241 −1 BCB 0.01875 RB. exhibited reusability, maintaining 93.5% efficiency after five cycles, structural stability throughout repeated use. These results underscore multifunctional potential green‐synthesized dye‐contaminated wastewater treatment, contributing technologies.
