Figure 2

The proposed electrode-reaction mechanism for organic product formation near the cathode of the microreactor. The image (IA–C) shows the CO2 reduction reaction at cathode leading to the formation of formate and formic acid. The image (IIA–C) shows the conversion of to alcohol near cathode, and the image (IIIA–C) shows the CO2 reduction reaction at cathode resulting in H2 gas evolution.
