Abstract
SrBi2Nb2O9 nanoplates were successfully synthesized by a hydrothermal method for the first time, using Sr(NO3)2, Bi2O3, and Nb2O5 as the starting materials and KOH as the mineralizer. The influences of the reaction conditions on the phases and morphologies of the products were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). SEM results revealed that the as-prepared particles were plate shaped. Diffuse reflectance spectra (DRS) showed the band gap of SrBi2Nb2O9 was 2.15 eV. Meanwhile, the photocatalytic activity for the decolorization of methylene blue under ultraviolet light irradiation and electrochemical properties of SrBi2Nb2O9 plates were evaluated.
