Enhanced photocatalytic behaviour of synthesized nickel oxide nanoparticles on Fluorescein under different irradiations

The NiO nanoparticles were synthesized by the solution method and its enhanced photo catalytic activity on Fluorescein, a synthetic dye, was studied. The as synthesized nanoparticles were characterized by the various characterization techniques like powder-X-ray diffraction (XRD), scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) analysis. The degradation of Fluorescein under Sun light, UV and CFL irradiation was evaluated. From the results it was found that the synthesized NiO nanoparticles exhibited higher photo catalytic activity under Sun light and then the Compact Fluorescent Light (CFL) irradiation.
