Manganese(i) tricarbonyl complexes such as [Mn(bpy)(CO)3L] (L = Br, or CN) are known to be electrocatalysts for CO2 reduction to CO. However, due to their rapid photodegradation under UV and visible light, these monomeric manganese complexes have not been considered as photocatalysts for CO2 reduction without the use of a photosensitizer. In this paper, we report a cyanide-bridged di-manganese complex, {[Mn(bpy)(CO)3]2(μ-CN)}ClO4, which is both electrocatalytic and photochemically active for CO2 reduction to CO. Compared to the [Mn(bpy)(CO)3CN] electrocatalyst, our CN-bridged binuclear complex is a more efficient electrocatalyst for CO2 reduction using H2O as a proton source. In addition, we report a photochemical CO2 reduction to CO using the dimanganese complex under 395 nm irradiation.
锰(i)三羰基配合物，如[Mn(bpy)(CO)3L]（L = Br 或 CN），已知是 CO2 还原为 CO 的电催化剂。然而，由于它们在紫外光和可见光下迅速光降解，这些单核锰配合物在没有使用光敏剂的情况下，尚未被考虑作为 CO2 还原的光催化剂。在本文中，我们报告了一种氰基桥联二锰配合物，{[Mn(bpy)(CO)3]2(μ-CN)}ClO4，它对 CO2 还原为 CO 具有电催化和光化学活性。与[Mn(bpy)(CO)3CN]电催化剂相比，我们的 CN 桥联双核配合物是使用 H2O 作为质子源还原 CO2 的更有效的电催化剂。此外，我们还报道了在 395nm 照射下使用二锰配合物进行光化学 CO2 还原为 CO。
