“…(SmL)2CO3 is a stable off-cycle species that hampers catalysis; its formation can be slowed down by diluting the reaction mixture. 21,32 Decreasing [SmL] from 1 mM to 1 µM increased the yield from nCO = 0.14 mmol to 0.75 mmol (Figure 2a). The corresponding TONCO = 378000 is the highest reported to date for any photocatalytic system (Table S9).…”

CO2 conversion to value-added chemicals is a crucial technology towards carbon-neutral fuels.1 Photocatalysis using sunlight is an energy-efficient alternative to electrochemical and thermal CO2 reduction.1 Photocatalysts usually yield either CO or HCO2H with varying degrees of selectivity.1 Herein, a lanthanide-based photocatalytic platform producing CO, HCO2H, CH4 or CH3OH is reported. The catalyst consists of a pendant amine for CO2 capture and a light-harvesting sensitiser that generates the reactive divalent lanthanide centre. CO2 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 CO2 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.

“…While most investigations of the carbonate-bridged polynuclear Ln III complexes have been focused on solid state characterization only, 28–46,53 reports concerning detailed solution studies of such compounds are limited. 47–49,54,56–61 In fact, some research revealed that the dimeric and trimeric carbonate-bridged polynuclear Ln III complexes may dissociate in solution, resulting in the equilibrium mixture. 47,56–58…”
