Synthesis of Bi2O3 Nanosheets and Photocatalysis for Rhodamine B

Abstract

Bi2O3 nanosheets (NSB) photocatalyst was fabricated via a very simple method of liquid precipitation. The as obtained products were characterized by SEM, N2 adsorption-desorption, XRD and UV-vis diffuse reflectance spectra. The results showed that NSB catalyst can beconsidered as set of nanosheets with an average thickness of 110 nm. NSB photocatalyst exhibited high surface area of 33.21 m2/g and high purity. In addition, NSB catalyst displayed excellent photocatalytic performance for the dye of rhodamine B (Rh B) under visible light due to the structure of sheet and high surface area.
