Unveiling the role of proton concentration in dinuclear metal complexes for boosting photocatalytic CO₂ reduction.

ABSTRACT: The reaction kinetics of photocatalytic CO₂ reduction is highly dependent on the transfer rate of electrons and protons to the CO₂ molecules adsorbed on catalytic centers. Studies on uncovering the proton effect in catalysts on photocatalytic activity of CO₂ reduction are significant but rarely reported. In this paper, we, from the molecular level, revealed that the photocatalytic activity of CO₂ reduction is closely related to the proton availability in catalysts. Specifically, four dinuclear Co(II) complexes based on Robson-type ligands with different number of carboxylic groups (-nCOOH; n = 0, 2, 4, 6) were designed and synthesized. All these complexes show photocatalytic activity for CO₂ reduction to CO in a water-con
