Photocatalytic reduction of CO2 by two-dimensional Zn-MOF-NH2/Cu heterojunctions
CATALYSIS COMMUNICATIONS(2023)
Abstract
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 mu mol/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 pho-tocatalysts in catalytic CO2 reduction.
