Visible light photocatalytic CO2 reduction using a Ru(II) complex supported by N,N'-bis(diphenylphosphino)-2,6-diamino)pyridine ("PNP") ligands, an unprecedented molecular architecture for this reaction, breaks the domination of α-diimine ligands after more than three decades. These competent catalysts transform CO2 to formic acid with high selectivity and turnover numbers. A proposed mechanism, with combined electron transfer and catalytic cycles, successfully modeled the experimental rate of formic acid production.
