The catalyst consists of a pendant amine for CO 2 capture and a light-harvesting sensitiser that generates the reactive divalent lanthanide centre. CO 2 reduction to CO or formate was possible with >99% selectivity and with the highest turnover number reported for a photocatalyst by virtue of a distinct mechanistic pathway. Attractive (bi)carbonate CO 2 feedstocks were efficiently converted to CO, and CO could be reduced to the secondary products methane and methanol, demonstrating the wide utility of the platform.
