Photocatalytic and Antibacterial Activity of CoFe[sub.2]O[sub.4] Nanoparticles from IHibiscus rosa-sinensis/I Plant Extract

Biogenic CoFe[sub.2] O[sub.4] nanoparticles were prepared by co-precipitation and Hibiscus rosa sinensis plant leaf was used as a bio-reductant of the nanoparticle productions. The biosynthesized CoFe[sub.2] O[sub.4] nanoparticles were characterized by XRD, FTIR, UV, VSM, and SEM via EDX analysis. The cubic phase of biosynthesized CoFe[sub.2] O[sub.4] nanoparticles and their crystallite size was determined by XRD. The Co-Fe-O bonding and cation displacement was confirmed by FTIR spectroscopy. The presence of spherically-shaped biosynthesized CoFe[sub.2] O[sub.4] nanoparticles and their material were confirmed by SEM and TEM via EDX. The super-paramagnetic behaviour of the biosynthesized CoFe[sub.2] O[sub.4] nanoparticles and magnetic pulse was established by VSM analysis. Organic and bacterial pollutants were eradicated using the biosynthesized CoFe[sub.2] O[sub.4] nanoparticles. The spinel ferrite biosynthesized CoFe[sub.2] O[sub.4] nanoparticles generate radical and superoxide ions, which degrade toxic organic and bacterial pollutants in the environment.
