Implication

Laboratory study demonstrates efficient carbon monoxide electroreduction to acetate via interface engineering, highlighting a low-carbon approach for sustainable chemical synthesis.

Key Points

To achieve efficient and selective carbon monoxide electroreduction to acetate by directing protonation pathways and suppressing competing hydrogen evolution.
Engineered the solid/liquid/gas triple-phase interface to promote site-selective protonation and preferentially stabilize ketene intermediates.
Synthesized and tuned a cadmium-copper bimetallic catalyst combined with optimized interfacial water management.
Constructed a high-pressure membrane electrode assembly system to enhance carbon monoxide gas distribution and surface coverage.
The cadmium-copper catalyst demonstrated an acetate Faradaic efficiency of 75% alongside suppressed hydrogen evolution (<0.2% H2 Faradaic efficiency) at 150 mA cm−2.
The high-pressure membrane electrode assembly achieved an acetate Faradaic efficiency of 86% with a full-cell energy efficiency of 32%.
