RGO-MnNb₂O₆ photocatalysts were successfully prepared through the hydrothermal and photo-reduction processes. Compared with single MnNb₂O₆, the RGO-MnNb₂O₆ composites could significantly enhance photocatalytic activity for the degradation of methylene blue under visible light irradiation. Within 60 min, 78.2% of the methylene blue was removed by the optimum sample (3% RGO-MnNb₂O₆), which was about 2 times higher than that of the individual MnNb₂O₆. By further study based on the active species trapping experiments, the enhanced photocatalytic property could be ascribed to the crucial role of RGO, which widely accelerated the separation of photogenerated electron-hole pairs. In general, the RGO hybridized with MnNb₂O₆ could address the problem of low photocatalytic activity.
