A possible mechanism for boosting the visible-light photoactivities of graphitic carbon nitride (g-C₃N₄) nanosheets for CO₂ reduction via coupling with the electron donor Co-metal-organic framework (MOF) is proposed in this study. Specifically, Co-MOF as an electron donor is capable of transferring the photogenerated electrons in the lowest unoccupied molecular orbital (LUMO) to the conduction band of g-C₃N₄ to facilitate charge separation. As expected, the prepared Co-MOF/g-C₃N₄ nanocomposites display excellent visible-light-driven photocatalytic CO₂ reduction activities. The CO production rate of 6.75 µmol g^-1 h^-1 and CH₄ evolution rate of 5.47 µmol g^-1 h^-1 are obtained, which are approximately 2 times those obtained with the original g-C₃N₄ under the same conditions. Based on a series of analyses, it is shown that the introduction of Co-MOF not only broadens the range of visible-light absorption but also enhances the charge separation, which improves the photocatalytic activity of g-C₃N₄ to a higher level. In particular, the hydroxyl radical (·OH) experiment was operated under 590 nm (single-wavelength) irradiation, which further proved that the photogenerated electrons in the LUMO of Co-MOF can successfully migrate to g-C₃N₄. This work may provide an important strategy for the design of highly efficient g-C₃N₄-based photocatalysts for CO₂ reduction.
