By modifying CuO nanowire electrodes with a thick Nafion overlayer, a hydrophobic electrode surface was constructed, which enhanced the selectivity of CO2 RR and suppressed HER activity. This work emphasizes the importance of hydrophobicity in the selectivity of CO2 reduction.
Copper-based materials could produce a series of products through the CO2 electroreduction reaction, and are regarded as the most promising catalysts to produce fuels and value-added chemicals using renewable energy sources. However, the competitive hydrogen evolution reaction (HER) is a daunting challenge for the selectivity of carbonaceous products. Here, a hydrophobic electrode surface was constructed by modifying the CuO nanowire electrode with a thick Nafion overlayer, which exhibited enhanced selectivity toward the CO2 RR (especially for CO) and suppressed HER activity. This work highlights the importance of hydrophobicity in the selectivity of CO2 reduction and hints at the additional role of Nafion in powder-based catalyst electrodes.
