Abstract The design of bifunctional electrocatalysts toward reduction reaction carbon dioxide (ECO 2 RR) and oxygen evolution (OER) in aqueous rechargeable Zn─CO batteries (ZABs) still poses a significant challenge. Herein, Ni clusters (Ni x ) 0.5 0.8 nm diameter coupled with single site (Ni−N 4 −C), denoted as Ni−N /Ni 5 8 , respectively, are synthesized the size effect nanoclusters studied. exhibits an ≈100% Faradaic efficiency ( FE CO ECO RR for from −0.4 to −0.8 V versus reversible hydrogen electrode, superior that −C = 55.0%) 80.0%). OER performance or comparable commercial RuO but outperform −C.

High-purity CO2 rather than dilute (15 vol %, CO2/N2/O2 = 15:80:5, v/v/v) similar to the flue gas is currently used as feedstock for electroreduction of CO2, and liquid products are usually mixed up with cathode electrolyte, resulting in high product separation costs. In this work, we showed that a microporous conductive Bi-based metal–organic framework (Bi-HHTP, HHTP 2,3,6,7,10,11-hexahydroxytriphenylene) can not only efficiently capture from under humidity but also catalyze adsorbed into formic acid current density 80 mA cm–2 Faradaic efficiency 90% at very low cell voltage 2.6 V.

The synergistic interaction between the isolated metal sites promoted electrocatalytic activity of catalysts. However, structural heterogeneity makes it challenging to evaluate this effect accurately. In work, metal-coordinated polyphthalocyanine molecules (Fe-PPc, Co-PPc, FeCo-PPc) with long-range ordered and precise coordination structures are used as a platform study synergies different in electrochemical CO2 reduction reaction. combination means experimental theoretical calculation clearly reveal that coexistence Fe Co PPc significantly enhances conjugation macrocycle. This enhancement subsequently causes lose more electrons, thereby improving their adsorption facilitating formation intermediate *COOH on them. As result, FeCo-PPc achieves CO partial current density about 57.4 mA/cm2 high turnover frequency over 49000 site–1 h–1 at −0.9 V (vs RHE).

The electrochemical conversion of carbon dioxide (CO2) to valuable chemicals is gaining significant attention as a pragmatic solution for achieving neutrality and storing renewable energy in usable form. Recent research increasingly focuses on designing electrocatalysts that specifically convert CO2 into ethanol, desirable product due its high-energy density, ease storage, portability. However, high-efficiency ethanol production remains challenge compared ethylene (a competing with similar electron configuration). Existing electrocatalytic systems often suffer from limitations such low efficiency, poor stability, inadequate selectivity toward ethanol. Inspired by recent progress the field, this review explores fundamental principles material advancements electroreduction, emphasizing strategies over ethylene. We discuss electrocatalyst design, reaction mechanisms, challenges, future directions. These aim bridge gap between current industrialized applications technology.
