Cupric CO₂ conversion: The photocatalytic reduction of CO₂ to CO by a [Cu(qpy)]²⁺ (qpy: quaterpyridine) is highly efficient and selective. In MeCN solution in the presence of Ru(bpy)₃²⁺ (bpy: bipyridine), BIH (1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]imidazole) and TEOA (triethanolamine), and 3 % H₂O, high turnover number and selectivity are obtained, the highest among molecular 3d-metal catalysts reported so far.
