Abstract Acidic electrochemical CO 2 conversion is a promising alternative to overcome the low utilization. However, over-reliance on highly concentrated K + inhibit hydrogen evolution reaction also causes (bi)carbonate precipitation interfere with catalytic performance. In this work, under screening and guidance of computational simulations, we present carbon coated tip-like O 3 electrocatalyst for stable efficient acidic synthesize formic acid (HCOOH) concentration. The layer protects oxidized species higher intrinsic activity from reductive corrosion, peripherally formulates tip-induced electric field regulate adverse H attraction desirable enrichment. an electrolyte at pH 0.94, only 0.1 M required achieve Faradaic efficiency (FE) 98.9% 300 mA cm −2 HCOOH long-time stability over100 h. By up-scaling electrode into 25 electrolyzer setup, total current 7 A recorded sustain durable production 291.6 mmol L −1 h .

Electrochemical CO2 reduction to multicarbon products is vital for renewable fuels. While copper catalysts are effective C2+ production, the instability of Cu+ species hinders long-term performance. The present study reports development a Cu2O-PdO heterojunction and investigates influence an unoccupied orbital energy level regulation strategy on stabilization interfacial crystalline Cu2O during reaction (CO2RR). hybrid catalyst showed significant improvement, with 84% higher Faradaic efficiency C2H4, lasted over 7 h, vastly outperforming 2 h benchmark Cu2O. In-situ Raman, ex-situ XRD, theoretical calculations reveal that broadened d-orbital in PdO provides lower electrons, which contributes adjacent ions, high active interface significantly lowers barrier CO-CO dimerization step (2*CO → *OCCO) enhances selectivity activity CO2RR ethylene.
