(a) The cyclic voltammograms (CVs) of the anode at different times (inset demonstrates the relationship between time and acetate concentration). (b) The LSV of the cathode under various conditions (black line: CO₂ travel through the tube was allowed under light illumination; red line: CO₂ travel through the silicon tube was blocked under light illumination; blue line: CO₂ was allowed to travel through the tube in the dark).
