Tuning photocatalytic CO2 reduction reaction performance via nodes and dimensionality in metal–organic frameworks

Abstract

This work details the synthesis of a 3D MOF, Co³-MOF-3, from two precursors: a 1D chain (Co¹-MOF-1) and a 2D layer (Co⁸-MOF-2), linked via single-crystal-to-single-crystal transformation. Notably, the 2D precursor, Co⁸-MOF-2, demonstrated exceptional activity for photocatalytic CO₂ reduction, with a rate of 2004.3 µmol g⁻¹ h⁻¹.
