Molybdenum-doped Ilmenite/Graphitic Carbon Nitride Photocatalyst under Visible Light |
| 초록 |
Recently, Ilmenite NiTiO3 semiconductor is famous for their visible responded activity. However, it consumes issues in excited charge transfer during irradiated. In this study, the Mo-doped NiTiO3/g-C3N4 composites are synthesized in order to improve the photocatalytic activity by inhibiting electron-holes recombination. The NiTiO3/g-C3N4 composite was reported that can inhibit the recombination rate by transfer electrons that generated from NiTiO3 to g-C3N4 phase and resulting in the improvement of their photocatalytic activity under visible-light irradiation. On the other hand, doping Mo into NiTiO3 structure increased surface areas due to the reduction in nanoparticle sizes and inhibited the recombination process because of the generation of defect sites in the NiTiO3 lattice. The novel combination of g-C3N4 and Mo-doped NiTiO3 as a composite photocatalyst can bring synergistic effect as Z-scheme photocatalyst where photogenerated electrons and holes are efficiently separated, enhancing the photocatalytic activity under visible-light irradiation. |
