Enhanced photocatalytic dye degradation and hydrogen production ability of Bi(25)FeO(40)-rGO nanocomposite and mechanism insight

A comprehensive comparison between BiFeO(3)-reduced graphene oxide (rGO) nanocomposite and Bi(25)FeO(40)-rGO nanocomposite has been performed to investigate their photocatalytic abilities in degradation of Rhodamine B dye and generation of hydrogen by water-splitting. The hydrothermal technique adap...

description A comprehensive comparison between BiFeO(3)-reduced graphene oxide (rGO) nanocomposite and Bi(25)FeO(40)-rGO nanocomposite has been performed to investigate their photocatalytic abilities in degradation of Rhodamine B dye and generation of hydrogen by water-splitting. The hydrothermal technique adapted for synthesis of the nanocomposites provides a versatile temperature-controlled phase selection between perovskite BiFeO(3) and sillenite Bi(25)FeO(40). Both perovskite and sillenite structured nanocomposites are stable and exhibit considerably higher photocatalytic ability over pure BiFeO(3) nanoparticles and commercially available Degussa P25 titania. Notably, Bi(25)FeO(40)-rGO nanocomposite has demonstrated superior photocatalytic ability and stability under visible light irradiation than that of BiFeO(3)-rGO nanocomposite. The possible mechanism behind the superior photocatalytic performance of Bi(25)FeO(40)-rGO nanocomposite has been critically discussed.
