From: Nanobubble-infused electrolytes for enhanced mass transfer in liquid-fed CO2 electroreduction
Electrochemical performance including the total current density (a), CO partial current density (b), and CO Faradaic efficiency (c) as a function of applied voltage with 85% iR compensation for the cases of reference and nanobubble. The results show both experimental and numerical predicted data for the H-cell with 0.1 M KHCO3 electrolyte and Ag planar cathode. d The applied voltage breakdown for reference and nanobubble cases. e CO2 and OH- concentration distributions of electrode interface as a function of current densities of CO2RR as well as the location of diffusion layer with the insert figure indicating the 1D model for diffusion layer. f CO2 flux analysis as a function of CO partial current density in nanobubble case.
