Construction of robust Cu-MOFs from bifunctional pyridine-hydroxamate linkers for photocatalytic CO2 reduction

Robust Cu-MOFs with distinct topologies were prepared from the same bifunctional 4-pyridine-hydroxamate ligand. A favourable collection of porosity, framework stability, electronic structure, and photochemical properties was revealed for the SUM-33 MOF, which was later experimentally verified as an efficient and selective photocatalyst for CO₂-to-CO conversion.
