Incorporation of iron hydrogenase active sites into a highly stable metal–organic framework for photocatalytic hydrogen generation

Abstract

A new biomimetic heterogeneous photocatalyst ([FeFe]@ZrPF) has been synthesized through the incorporation of homogeneous complex 1 [(í-SCH₂)₂NC(O)C₅H₄N]–[Fe₂(CO)₆] into the highly robust zirconium-porphyrin based metal–organic framework (ZrPF). The immobilized biomimetic [Fe₂S₂] catalyst inside the MOF shows great improvement in hydrogen generation compared to the reference homogeneous catalyst complex 1.
