Enhanced photocatalytic dye degradation and hydrogen production ability of Bi₂₅FeO₄₀-rGO nanocomposite and mechanism insight.

ABSTRACT: A comprehensive comparison between BiFeO₃-reduced graphene oxide (rGO) nanocomposite and Bi₂₅FeO₄₀-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 BiFeO₃ and sillenite Bi₂₅FeO₄₀. Both perovskite and sillenite structured nanocomposites are stable and exhibit considerably higher photocatalytic ability over pure BiFeO₃ nanoparticles and commercially available Degussa P25 titania. Notably, Bi₂₅FeO₄₀-rGO nanocomposite has demonstrated s
