Electrochemical carbon dioxide reduction reaction (CO2RR) provides a promising way to convert CO2 chemicals. The multicarbon (C2+) products, especially ethylene, are of great interest due their versatile industrial applications. However, selectively reducing ethylene is still challenging as the additional energy required for C-C coupling step results in large overpotential and many competing products. Nonetheless, mechanistic understanding key steps preferred pathways/conditions, well rational design novel catalysts production have been regarded approaches achieving highly efficient selective CO2RR. In this review, we first illustrate CO2RR (e.g., adsorption/activation, formation *CO intermediate, step), offering conversion ethylene. Then alternative pathways conditions competitive products (C1 other C2+ products) investigated, guiding further development generation. Engineering strategies Cu-based CO2RR-ethylene summarized, correlations mechanism/pathways, engineering selectivity elaborated. Finally, major challenges perspectives research area proposed future practical

Abstract Copper‐based tandem catalysts with a well‐defined Cu coordination environment for the electrochemical CO 2 reduction reaction (CO RR) are highly desirable, due to their unique geometric‐electronic properties and helpfulness revealing structure–property correlations. Here, this work synthesizes catalyst at atomic configuration scale, Ag@BIF‐104NSs(Cu), by using ultrathin boron imidazolate framework (BIF) nanosheets as support load Ag nanoparticles (NPs). Due ordered benzoate ligands decorated on sites of BIF‐104NSs(Cu), NPs located in proximity via effect. Electrochemical RR measurements show improves selectivity activity ethylene. The faradaic efficiency (FE C2H4 ) 21.43% is significantly higher than that BIF‐104NSs(Cu) (3.82%). Further, density functional theory calculations reveal composite can efficiently reduce *CO, subsequently migrate sites. Thereafter, Cu–Ag atom pair responsible C–C coupling local enriched *CO further formation C H 4 .

Zeolitic metal-organic frameworks (ZMOFs) have emerged as one of the most promsing catalysts for energy conversion, but they suffer from either weak bonding between cubes (MOCs) that decrease their stability during catalysis processes or low activity due to inadequate active sites. In this work, through ligand-directing strategy, we successfully obtain an unprecedented bismuth-based ZMOF (Bi-ZMOF) featuring a ACO topological crystal structure with strong coordination Bi-based cages. As result, it enables efficient reduction CO2 formic acid (HCOOH) Faradaic efficiency high 91 %. A combination in situ surface-enhanced infrared absorption spectroscopy and density functional theory calculation reveals Bi-N contributes facilitating charge transfer N Bi atoms, which stabilize intermediate boost HCOOH. This finding highlights importance environment metal sites on electrocatalytic reduction. We believe work will offer new clue rationally design zeolitic MOFs catalytic reaction.

It is crucial to achieve continuous production of highly concentrated and pure C2 chemicals through the electrochemical CO2 reduction reaction (eCO2RR) for artificial carbon cycling, yet it has remained unattainable until now. Despite one-pot tandem catalysis (dividing eCO2RR into two catalytical reactions CO C2) offering potential significantly enhancing efficiency, its mechanism remains unclear performance unsatisfactory. Herein, we selected different CO2-to-CO catalysts CO-to-acetate construct several catalytic systems acetic acid.
