摘要：

The selectivity of the CO2 photoreduction reaction in the presence of water vapour can be modulated by the band structure of a g-C3N4 photocatalyst. The major products obtained using bulk g-C3N4 with a bandgap of 2.77 eV and g-C3N4 nanosheets with a bandgap of 2.97 eV are acetaldehyde (CH3CHO) and methane (CH4), respectively.
