Homoleptic terpyridine complexes of first row transition metals are evaluated as catalysts for the electrocatalytic reduction of CO2. Ni and Co-based catalytic systems are shown to reduce CO2 to CO under the conditions tested. The Ni complex was found to exhibit selectivity for CO2 over proton reduction while the Co-based system generates mixtures of CO and H2 with CO : H2 ratios being tuneable through variation of the applied potential.
对第一行过渡金属的均配三联吡啶配合物作为二氧化碳电催化还原催化剂进行了评估。结果表明，镍基和钴基催化体系在测试条件下可将二氧化碳还原为一氧化碳。发现镍配合物对二氧化碳的选择性高于质子还原，而钴基体系生成一氧化碳和氢气的混合物，一氧化碳与氢气的比例可通过改变外加电势进行调节。
