一种受一氧化碳脱氢酶活性位点启发的、带有S2N2型四齿配体的镍（II）配合物，在以[Ru(bpy)₃]²⁺（bpy = 2,2'-联吡啶）为光敏剂和1,3 - 二甲基 - 2 - 苯基 - 2,3 - 二氢 - 1H - 苯并[d]咪唑（BIH）为电子供体的光催化体系中，被发现能选择性地催化二氧化碳还原生成一氧化碳。该镍（II）配合物在光催化体系中展现出超过700的高转化数，一氧化碳选择性>99%，量子产率为1.42%。
A Ni(II) complex bearing an S2N2-type tetradentate ligand inspired by the active site of carbon monoxide dehydrogenase was found to selectively catalyze CO2 reduction to produce CO in a photocatalytic system using [Ru(bpy)(3)](2+) (bpy = 2,2'-bipyridine) as a photo sensitizer and 1,3-dimethy1-2-pheny1-2,3-dihydro-1H-benzo[d]imidazole (BIH) as an electron donor. The Ni(II) complex shows a high turnover number over 700 with high CO selectivity of >99% and quantum yield of 1.42% in the photocatalytic system.
