Fig. 2From: Electroreduction of divanillin to polyvanillin in an electrochemical flow reactorLSV of the HER at the Zn cathode in the blank catholyte (black), at the Zn cathode with addition of 50 mM divanillin to the catholyte (red) and of the OER at the Ni anode (blue). Potentials were corrected by the iR-drop. Potential sweep rate: 3.33 mV s−1. Mean linear flow rate: 20 cm s−1Back to article page
