“…[40][41][42] Currently, a wide range of products has been produced through diverse reaction systems, including CO, formic acid, CH 4 , CH 3 OH, ethylene, ethane, ethanol and other C 2+ products. [43][44][45][46][47] As is shown in Figure 1B, after being absorbed onto electrode surface, the CO 2 molecule is then transformed into CO 2 ˙− or * CO intermediates over different electrode materials. 48 These two intermediates could directly desorb from the electrode to yield the 2-electron transfer products, CO and HCOOH.…”

The development of renewable-energy-powered electrocatalysis meets the need for the sustainable society. With water as the proton source, it enables efficient production of chemicals and fuels from renewable resources like CO2, N2, and NOx under ambient conditions. Hydrogen generated via water dissociation is a crucial participant in transforming reactants into desired products, but it also serves as a direct source of undesired reactions when in excess. In this review, we first present an overview of the functional mechanisms of active hydrogen in the electroreduction of CO2/N2/NOx. We then introduce a range of methods to enhance our understanding of these mechanisms. Furthermore, a detailed discussion of design strategies aimed at regulating active hydrogen in the reduction of CO2/N2/NOx is provided. Finally, an outlook on the critical challenges remaining in this research area and promising opportunities for future research is considered.

Electrochemical CO2 reduction presents a promising approach for synthesizing fuels and chemical feedstocks using renewable energy sources. Although significant advancements have been made in the design of catalysts for CO2 reduction reaction (CO2RR) in recent years, the linear scaling relationship of key intermediates, selectivity, stability, and economical efficiency are still required to be improved. Rare earth (RE) elements, recognized as pivotal components in various industrial applications, have been widely used in catalysis due to their unique properties such as redox characteristics, orbital structure, oxygen affinity, large ion radius, and electronic configuration. Furthermore, RE elements could effectively modulate the adsorption strength of intermediates and provide abundant metal active sites for CO2RR. Despite their potential, there is still a shortage of comprehensive and systematic analysis of RE elements employed in the design of electrocatalysts of CO2RR. Therefore, the current approaches for the design of RE element‐based electrocatalysts and their applications in CO2RR are thoroughly summarized in this review. The review starts by outlining the characteristics of CO2RR and RE elements, followed by a summary of design strategies and synthetic methods for RE element‐based electrocatalysts. Finally, an overview of current limitations in research and outline of the prospects for future investigations are proposed.
