2D metal–organic frameworks (2D-MOFs) have recently emerged as promising materials for gas separations, sensing, conduction, and catalysis. However, the stability of these 2D-MOF catalysts and the tunability over catalytic environments are limited. Herein, it is demonstrated that 2D-MOFs can act as stable and highly accessible catalyst supports by introducing more firmly anchored photosensitizers as bridging ligands. An ultrathin MOF nanosheet-based material, Zr-BTB (BTB = 1,3,5-tris(4-carboxyphenyl)benzene), is initially constructed by connecting Zr6-clusters with the tritopic carboxylate linker. Surface modification of the Zr-BTB structure was realized through the attachment of porphyrin-based carboxylate ligands on the coordinatively unsaturated Zr metal sites in the MOF through strong Zr-carboxylate bond formation. The functionalized MOF nanosheet, namely PCN-134-2D, acts as an efficient photocatalyst for 1O2 generation and artemisinin production. Compared to the 3D analogue (PCN-134-3D), PCN-134-2D allows for fast reaction kinetics due to the enhanced accessibility of the catalytic sites within the structure and facile substrate diffusion. Additionally, PCN-134(Ni)-2D exhibits an exceptional yield of artemisinin, surpassing all reported homo- or heterogeneous photocatalysts for the artemisinin production.
