  Reduction of Cobalt and Iron Corroles and Catalyzed Reduction of CO₂

  摘要：

  The role of cobalt and iron corroles in catalytic CO2 reduction has been studied. Chemical, electrochemical, and photochemical reductions of the stable metal corroles Ph3PCoIII(tpfc) (tpfc = 5,10,15-tris(pentafluorophenyl)corrole), ClFeIV(tpfc), and CIFeIV(tdcc) (tdcc = 5,10,15-tris(2,6-dichlorophenyl)corrole) have been carried out in acetonitrile solutions. Stepwise reduction to the [M-II(tpfc)](-) and [M-1(tpfc)](2-) states was observed in all cases. Gradual reduction with sodium amalgam permitted recording of the optical absorption spectra of the various oxidation states and showed that the M-1 state reacts with CO2. Cyclic voltammetry in Ar-saturated acetonitrile solutions permitted determination of the following half-wave potentials: for Ph3PCOIII (tpfc), 1.11 V, 0.72 V, -0.42 V (E-pc), - 1.44 V, -2.3 V (E-pc); for ClFeIV(tpfc), 0.44 V, - 1.01 V (E-pc), - 1.60 V, -2.2 V (E-pc); for ClFeIV(tdcc), 0.24 V, - 1.18 V (E-pc), - 1.78 V vs SCE with a scan rate of 0. 1 V s(-1). Cyclic voltammetry in CO2-saturated solutions indicated that the Co-1 and Fe-1 complexes react with CO2 and that the reduced Fe(tdcc) complex is the most efficient electrocatalyst for CO2 reduction, showing the largest catalytic currents among these corroles. Photochemical reduction in CO2-saturated acetonitrile solutions containing p-terphenyl (TP) as a sensitizer and triethylamine (TEA) as a reductant led to production of CO and H, These experiments also show that Fe(tdcc) is more effective than the other corroles as a CO2 reduction catalyst. The present finding that the M-1 oxidation states of the cobalt and iron corroles can react with CO2 is in contrast with the case of the respective porphyrins and phthalocyanines, which do not react with CO2 until they are reduced beyond the M-1 state.

  Herein, we report the use of cobalt and iron corrole complexes as catalysts of H2O reduction to generate H2. Electro‐ and photocatalysis has been used in the case of dissolved corroles for water reduction with inspiring results. Carbon nanotubes doped with corroles were used as photo‐electrochemical catalysts, with very low overpotential values and increased hydrogen production; incredibly high turnover

  在这里，我们报道了使用钴和铁的铁络合物作为H 2 O还原生成H 2的催化剂。对于溶解的助剂，已将电催化和光催化用于减少水份，从而产生令人鼓舞的结果。掺杂有环氧乙烷的碳纳米管被用作光电化学催化剂，具有极低的过电势值和增加的氢气产量。获得了令人难以置信的高周转率，分别达到了大约10 7和10 5的周转频率。通过最后一个过程，我们能够获得1 mmol的H 2通过使用微量的催化剂，数量级为皮克。反应可以在水中进行，而无需有机溶剂。值得注意的是，如果分子催化剂吸附在碳纳米管上，则光电化学催化效率提高了五个数量级。
