Electrocatalytic CO2 reduction and CO2/5-hydroxymethylfurfural co-conversion under ampere current densities

Key Points

• The aim is to improve the economic feasibility of CO2 reduction and its co-conversion with biomass-derived compounds.
• Developed a superthin nitrogen-doped bismuth nanosheet catalyst for CO2 reduction.
• Constructed an electrochemical system coupling cathodic CO2 reduction with anodic 5-hydroxymethylfurfural oxidation.
• Conducted experiments at industrial current densities of 0.7 A cm^-2.
• Measured Faradaic efficiencies for both formic acid and 2,5-furandicarboxylic acid.
• Achieved a Faradaic efficiency of 98.1% for formic acid production.
• Attained a Faradaic efficiency of 91.0% for 2,5-furandicarboxylic acid production.
• Demonstrated high reaction activity and product selectivity under ampere current densities.
