The two-dimensional (2D) Zn-MOF-NH2/Cu heterojunctions were prepared via in situ photodeposition of Cu NPs on the surface of 2D Zn-MOF-NH2. The 2D Zn-MOF-NH2/Cu (1 wt%) heterojunction exhibited the excellent photocatalytic activity with a CO production rate of 0.76 μmol/h under irradiation of full spectrum light only using H2O as a hole sacrificial agent, which is 16.2 and 2.7 times that of bulk Zn-MOF-NH2 and 2D Zn-MOF-NH2 nanosheets, respectively. This work provides an insight into design of a highly efficient 2D MOFs-based photocatalysts in catalytic CO2 reduction. •2D Zn-MOF-NH2 nanosheets were prepared by a mild method.•2D Zn-MOF-NH2/Cu heterojunctions have excellent activity in photocatalytic reduction of CO2.•The CO generation rate of 2D Zn-MOF-NH2/Cu (1 wt%) is 16.2 times that of bulk Zn-MOF-NH2.
