Abstract

A comprehensive comparison between Bi $_{25}$ FeO $_{40}$ -reduced graphene oxide(rGO) nanocomposite and BiFeO $_{3}$ -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.
