Bio‐Inspired Synthesis and Photocatalytic Applications of α‐Fe₂O₃@ZnO Nanobinary Using Laurus nobilis Leaf Extract: Efficient for Anionic and Cationic Dye Degradation With Reusability Studies

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 the formation of the nanocomposite with a crystallite size of 21.48 nm, while SEM revealed a porous structure with uniformly distributed particles ranging from 20 to 50 nm. FTIR spectroscopy identified characteristic Fe‐O and Zn‐O bonds, ensuring the nanocomposite's purity. Optical analysis showed direct and indirect bandgap energies of 2.80 and 1.16 eV, respectively, highlighting its excellent optical properties. The nanocomposite…
