The increasing concentration of CO in the atmosphere has caused various environmental issues. Utilizing CO as the carbon feedstock to replace traditional fossil sources in commodity chemical production is a potential solution to reduce CO emissions. Electrochemical reduction of CO has attracted much attention because it not only converts CO into a variety of useful chemicals under mild reaction conditions, but also can be powered by renewable electricity at remote locations. From this review article, we summarize recent literature on the topic of bimetallic electrocatalysts for CO reduction. Both selectivity and activity of bimetallic catalysts strongly depend on their compositions and surface structures. Tuning the properties of a bimetallic catalyst could result in a wide range of products, including carbon monoxide, hydrocarbons, carboxylate and liquid oxygenates. By reviewing recent research efforts in the field of bimetallic electrocatalysts for CO reduction, we aim to provide the community with a timely overview of the current status of bimetallic CO electrocatalysts and to stimulate new ideas to design better catalysts for more efficient CO electrolysis processes.
大气中 CO 浓度的不断增加导致了各种环境问题。利用 CO 作为碳原料替代商品化学生产中的传统化石资源，是减少 CO 排放的一种潜在解决方案。电化学还原 CO 引起了广泛关注，因为它不仅可以在温和的反应条件下将 CO 转化为各种有用的化学品，而且可以在偏远地区由可再生电力驱动。从这篇综述文章中，我们总结了关于双金属电催化剂用于 CO 还原的最新文献。双金属催化剂的选择性和活性强烈依赖于它们的组成和表面结构。调整双金属催化剂的性质可以得到广泛的产物，包括一氧化碳、碳氢化合物、羧酸盐和液态含氧化合物。通过回顾双金属电催化剂用于 CO 还原的最新研究进展，我们旨在为该领域的研究人员提供对双金属 CO 电催化剂当前状况的及时概述，并激发新的思路，以设计更好的催化剂，实现更高效的 CO 电解过程。
