| Abstract | Nb2O5 nanoparticles have been successfully synthesized and modified via a hydrothermal process on commercial Nb2O5 powder. In the reaction process, in addition to the commercial Nb2O5 powder, H2O2 and NH3 aqueous solutions have also been used as precursors. The crystallographic phases and optical properties were examined by X-ray diffraction (XRD) and diffuse reflectance (DR) UV–vis spectroscopic methods, respectively. Morphology of the produced samples were studied using a field emission scaning electron microscope (FE-SEM). The photocatalytic activity of modified Nb2O5 NPs on degradation of MB and RhB dyes were examined, that obtained results show higher photocatalytic efficiency for MB dye compared to RhB. This efficiency difference has been attributed to the chemical structure of the dyes and the nature of functional groups attached on the dye molecule. Photodegradation of MB and RhB in water follows roughly the pseudo-first-order reaction. |
