| Abstract: 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. |
