chSchematic illustrations of porous electrodes submerged in the nanobubble-infused electrolyte at the construction of hydrophobic DM coating with nano-Ag catalyst (a), hydrophilic DM coating with nano-Ag catalyst (b), and hydrophilic DM coating with NiPC-OMe MDE catalyst (c). Characteristics of electrochemical performance with CO partial current density (d) and CO Faradaic efficiency (e) in reference (dash lines) and nanobubble (solid lines) case with IrO2-Ti anode using 0.1 M KHCO3 as the anolyte for CO2 conversion into CO in the zero-gap liquid-fed electrolyzer. f Water saturation and CO2 concentration distribution in the zero-gap liquid-fed electrolyzer for different structures of cathode electrode via simulation prediction (Case 1 and Case 2).
