Atmospheric CO is a cheap and abundant source of carbon for synthetic applications. However, the stability of CO makes its conversion to other carbon compounds difficult and has prompted the extensive development of CO reduction catalysts. Bioelectrocatalysts are generally more selective, highly efficient, can operate under mild conditions, and use electricity as the sole reducing agent. Improving the communication between an electrode and a bioelectrocatalyst remains a significant area of development. Through the examples of CO reduction catalyzed by electroactive enzymes and whole cells, recent advancements in this area are compared and contrasted.
大气中的 CO 是合成应用中廉价且丰富的碳源。然而，CO 的稳定性使其向其他碳化合物的转化变得困难，这促使了 CO 还原催化剂的广泛开发。生物电化学催化剂通常具有更高的选择性、更高的效率，可以在温和条件下运行，并且仅使用电力作为还原剂。提高电极与生物电化学催化剂之间的通讯仍然是一个重要的发展领域。通过比较电活性酶和完整细胞催化 CO 还原的实例，本文对该领域的最新进展进行了对比和讨论。
