• The exploitation of highly stable and active catalysts for the conversion of CO2 into valuable fuels is desirable but is a great challenge. Herein, we report that the incorporation of chromophores into metal–organic frameworks (MOFs) could afford robust catalysts for efficient CO2 conversion. Specifically, a porous Nd­(III) MOF (Nd-TTCA; TTCA3– = triphenylene-2,6,10-tricarboxylate) was constructed by incorporating one-dimensional Nd­(CO2) n chains and TTCA3– ligands, which exhibits a very high stability, retaining its framework not only in the air at 300 °C for 2 h but also in boiling aqueous solutions at pH 1–12 for 7 days. More importantly, Nd-TTCA has achieved a 5-fold improvement in photocatalytic activity for reducing CO2 to HCOOH and a 10-fold improvement in catalytic activity for the cycloaddition of CO2 into cyclic carbonate in comparison to those of H3TTCA itself. This work gives a new strategy to design efficient artificial crystalline catalysts for CO2 conversion.
