Beyond scaling relations in electrocatalysis: unifying concepts from molecular systems and metallic surfaces.

Transitioning the chemical industry away from fossil fuels is a critical goal that requires the adoption of alternative, non-fossil carbon feedstocks. The electrochemical CO reduction reaction, driven renewable-derived electricity, represents an unparalleled technology that uses CO as a C-building block to generate industrially relevant products. Although many electrocatalytic systems have demonstrated promising activities in producing a wide range of products, challenges remain in controlling the product selectivity and reducing the operating overpotential for large-scale applications.
