摘要

本文报道了以三乙醇胺(TEOA)为配体，FeIII(TPA)Cl3 (TPA= 3-(2-吡啶甲基)胺)为对比催化剂的四种自组装铁(II/III)配合物在可见光下将CO2光化学还原为CO。以[Ru(bpy)3]Cl2为光敏剂，1,3-二甲基-2-苯基-2,3-二氢- 1h -苯并[d]-咪唑(BIH)为电子给体组装光催化体系。通过实验研究了CO的生成与外源离子的关系。提供了不同的外部反离子，以帮助讨论这些外部离子对催化的影响。密度泛函理论计算证实了外离子对CO产率的影响。此外，还提出了质子耦合电子转移的机制。

Photocatalytic System using Iron-Based Catalysts: Effect of External Ions on CO2-to-CO Conversion

Herein, we report four self-assembly Iron(II/III) complex consisting triethanolamine (TEOA) as ligand and an FeIII(TPA)Cl3 (TPA= 3-(2-pyridine methyl) amine) as contrast catalyst, for photochemical reduction of CO2 to CO under visible light. The photocatalytic systems were assembled by [Ru(bpy)3]Cl2 as photosensitizer, and 1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo-[d]-imidazole (BIH) as electron donor. Experiments are conducted to study the relationship between CO production and the external ions. Different external counterions are provided to assist the discussion of the influence of these external ions on catalysis. Density functional theory calculations confirmed that the external ions have an effect on the CO yield. Moreover, a mechanism involving proton-coupled electron transfer is proposed.
