Lateral CO Diffusion on Micropatterned Ag/CuO Arrays Enables Efficient CO2 -to-C2+ Electroreduction

Key Points

• The aim is to explore how lateral CO diffusion in micropatterned Ag/CuO arrays can enhance CO2 to C2+ electroreduction efficiency.
• Utilized micropatterned Ag/CuO arrays for CO2 reduction.
• Analyzed CO diffusion behavior on these patterns.
• Measured the selectivity and yield of C2+ products.
• Lateral CO diffusion significantly increases C2+ product yields.
• Improved selectivity for multi-carbon products was observed.
• The micropatterning technique led to higher overall efficiency in CO2 reduction.
