In situ self-assembly of zirconium metal–organic frameworks onto ultrathin carbon nitride for enhanced visible light-driven conversion of CO2 to CO

A series of Zr-porphyrin metal–organic framework (Zr-PMOF)/ultrathin g-C₃N₄ (UCN) heterostructure photocatalysts, as stable and efficient catalysts for the photoreduction of CO₂, have been fabricated via a facile in situ hydrothermal self-assembly method.
