AI Insight
This study investigates how temperature influences CO2 electroreduction by modifying the structure of interfacial water at the electrode surface. The researchers demonstrate that thermal regulation reshapes water organization at the electrocatalyst interface, which in turn controls the dominant reaction pathways for CO2 activation. By leveraging this mechanism, they achieved ampere-level current densities with near-unity Faradaic efficiency toward carbon monoxide (CO) production.
Why it matters
Selective and high-rate electrochemical conversion of CO2 to CO is a critical step toward closing the carbon cycle and enabling sustainable chemical feedstock production. This work provides a practical thermal-control strategy that could be implemented in industrial electrolyzers to improve both productivity and selectivity without requiring new catalyst materials.
