Advancing electrocatalytic CO reduction: key strategies for scaling up to industrial applications.

Electrocatalytic CO reduction (eCORR) to high value-added C products offers a highly promising pathway toward carbon neutrality and sustainable energy storage. However, the limited activity of current catalysts and the suboptimal configuration of reaction systems hinder the achievement of high C selectivity and long-term operational stability, falling short of industrial application requirements. In this review, we take a unique perspective to examine recent advances in the functional design of catalysts and the optimization of reactor systems. We highlight that rational catalyst design can enhance C product selectivity, while optimization of reactor components can improve system stability. The integration of innovative technologies with system-level optimization holds great potential to advance the scalability and economic feasibility of eCORR. This review bridges the gap between fundamental research and industrial application of eCORR, offering critical insights to guide its development as a practical and scalable technology.
