Steady Cu⁺ species via magnesium and boron co-modification for enhanced CO₂ electroreduction to C₂₊ products: an in situ Raman spectroscopic study

Abstract

Electrochemical carbon dioxide reduction reaction (CO2RR) to produce high-value multi-carbon (C2+) compounds holds significant practical importance in realizing carbon neutrality. Copper-based electrocatalysts are promising for CO2-to-C2+ conversion. However, the labile...
