Rücktitelbild: Bio‐Inspired Bimetallic Cooperativity Through a Hydrogen Bonding Spacer in CO ₂ Reduction (Angew. Chem. 8/2023)

Inspired by the active site of CO dehydrogenase, a metalloporphyrin-based mimic has been synthesized combining a multipoint hydrogen bond donor and a bimetallic active centre, as reported by Zakaria Halime, Ally Aukauloo et al. in their Communication (e202214665). The cooperativity between the two metal centres of the catalyst was shown for both homo- and heterobimetallic analogues, leading to a significant enhancement of the catalytic performance of the heterogeneous CO2-to-CO electrocatalytic reduction.
