Abstract

The electrochemical CO2 reduction reaction (CO2RR) driven by renewable energy to produce formic acid (FA) is one of the key pathways toward achieving carbon neutrality. Bi‐based materials have emerged as leading candidates among the diverse range of CO2 reduction catalysts due to their high activity, excellent selectivity, and relative abundance. Despite these advantages, their practical application is hindered by several critical challenges, including significant CO2 crossover losses, carbonate precipitation that deactivates active sites, and the production of low‐purity FA, which necessitates resource‐intensive separation processes. This review surveys the benefits, advantages, and challenges of Bi‐catalyzed CO2RR to form FA. Then, innovative strategies to overcome the barriers in Bi‐catalyzed CO2RR systems are systematically explored, focusing on advancements in electrolyte modulation and device design. These key approaches include: 1) the adoption of acidic electrolytes, 2) the implementation of solid‐state electrolytes (SSEs), and 3) the integration of bipolar membranes (BPM), thereby improving FA efficiency and device durability of Bi‐based CO2RR. Finally, we provide a brief outlook on the future opportunities for these technologies to accelerate the industrialization of CO2RR to FA.

铋基CO2 - to -甲酸电催化新装置设计及微环境调制研究进展

可再生能源驱动的电化学CO2还原反应（CO2RR）生成甲酸（FA）是实现碳中和的关键途径之一。铋基材料因其高活性、优异的选择性和相对丰度而成为各种CO2还原催化剂的主要候选材料。尽管有这些优势，但它们的实际应用受到几个关键挑战的阻碍，包括显著的二氧化碳交叉损失、碳酸盐沉淀使活性位点失活，以及低纯度FA的生产，这需要资源密集型的分离过程。本文综述了Bi催化CO2RR生成FA的优点、优势和挑战。然后，系统地探索了克服Bi催化CO2RR体系障碍的创新策略，重点关注了电解质调制和器件设计方面的进展。这些关键方法包括：1)采用酸性电解质，2)固态电解质（sse）的实施，以及3)双极膜（BPM）的集成，从而提高Bi基CO2RR的FA效率和器件耐用性。最后，我们对这些技术的未来机遇进行了简要展望，以加速CO2RR到FA的产业化。
