摘要

原位AFM揭示了CO₂诱导离子液体（IL）纳米膜的形态变化，这与CO₂的相互作用有关。GC电极和Au电极的伏安测量结果表明，在正离子相同但阴离子不同的电极中，BMIPF6、BMIDCA和BMINO3电极材料对CO₂的电化学还原起主导作用，而il对CO₂的还原表现出协同作用。反应电流的大小主要与离子的粘度有关

Unveiling CO2 Electrocatalytic Mechanisms in Ionic Liquids via Real-Time AFM and Voltammetry

In situ AFM has revealed CO₂-induced morphological changes of ionic liquid (IL) nanomembranes, which correlate with the interaction with CO₂. Voltammetry measurements on GC and Au electrodes suggest that in the ILs BMIPF₆, BMIDCA and BMINO₃, which have the same cation but different anions, the electrode material plays a dominant role in the electrochemical CO₂ reduction, while the ILs exhibit a synergistic effect on CO₂RR. The magnitude of the reaction current is primarily related to the viscosity of the ILs
