Characterization and photocatalytic activity of ZnO nanoflowers synthesized using Bridelia retusa leaf extract

Abstract In the current work, leaf extract of Bridelia retusa was used for first time to synthesize zinc oxide nanoparticles (ZnONPs). A nanoparticle-specific 364-nm peak discerned via UV–Vis studies with a typical bandgap energy 3.41 eV. FE-SEM micrographs revealed flower-shaped structure ZnONPs. EDS analysis corroborated presence and oxygen. XRD spectrum established wurtzite structure, sized at 11.06 nm. The mesoporous texture (4.89 nm) deduced from BET analysis, proving higher specific surface area than commercial FTIR spectroscopy resulted in absorption bands Within span 165 min, under solar irradiation, ZnONPs facilitated photocatalytic degradation Rhodamine B dye upto 94.74%. Exhibiting pseudo-first-order kinetics, process had constant 0.0109 min ?1 . It concluded that numerous factors led high efficiency. High values area, along crystalline nature observed effect. were also stabilized by phytochemicals B. leaves. study is thus able successfully demonstrate huge potential field environmental nanoremediation. viability using as photocatalysts treating dye-laden industrial wastewater attested.
