Pressure‐Enhanced CO2‐to‐CO Electroreduction on Ag‐Based Catalysts: Industrially Relevant Rates and Mechanistic Insights

open access: yesCarbon Energy, EarlyView.
Ag‐based catalysts operated under elevated CO2 pressures exhibit markedly enhanced intrinsic activity for CO formation, with OD‐Ag achieving −200 mA cm–2 and 90% FECO at −1.3 VRHE. Mechanistic analysis shows that high pressure strengthens a *COOH‐mediated pathway by increasing intermediate coverage and suppressing hydrogen evolution, establishing CO2 ...

Unveiling Synergistic CuAuAg Nanoparticles on CuO for High‐Yield CO2 Electroreduction

open access: yesCarbon Energy, EarlyView.
Pulsed laser irradiation in liquid synthesis was employed to fabricate a trimetallic catalyst composed of CuAuAg nanoparticles uniformly decorated on CuO nanosheets (CuAuAg/CuO composite). This catalyst exhibits remarkable electrocatalytic performance for the reduction of CO2 to CO, achieving a high CO yield rate of 5.1 mmol h−1 cm−2 and a Faradaic ...
