Over the past decade, there has been significant research in electrochemical reduction of CO, but it has been difficult to develop catalysts capable of C-C bond formation. Here, we report bioelectrocatalysis of vanadium nitrogenase from Azotobacter vinelandii, where cobaltocenium derivatives transfer electrons to the catalytic VFe protein, independent of ATP-hydrolysis. In this bioelectrochemical system, CO is reduced to ethylene (CH) and propene (CH), by a single metalloenzyme.
在过去的十年中，人们对 CO 的电化学还原进行了大量研究，但开发能够形成 C-C 键的催化剂一直具有挑战性。在这里，我们报告了来自固氮菌（Azotobacter vinelandii）的钒氮酶的生物电化学，其中钴卟啉衍生物将电子转移到催化 VFe 蛋白，而不依赖于 ATP 水解。在这个生物电化学系统中，CO 被单一的金属酶还原为乙烯（CH）和丙烯（CH）。
