Co-electrocatalytic CO2reduction mediated by a dibenzophosphole oxide and a chromium complex

“…The electrochemical reduction of CO 2 to CO requires the transfer of two electrons, typically mediated to the substrate via a catalytic system. 8–10 When electrons are transferred sequentially to a single site, their associated reduction potentials can be separated by hundreds of millivolts as the required driving force increases with each added charge. Biological systems address these energetic challenges with redox cofactors that mediate electron transfer to active sites, in order to perform multielectron catalysis with high efficiency and selectivity.…”
