Abstract
There is currently a great interest for the development of electrochemical reactors to be implemented for the emerged world-class reactions of hydrogen evolution (HER), CO2 reduction (CO2RR) and N2 reduction (N2RR) in order to electro-synthesize high value-added chemicals. However, precisely how this could be achieved in a cheap and sustainable way remains a puzzle for scientists since the electrochemical kinetics of the oxygen evolution reaction (OER) is the major limitation. An increasing interest surrounds the development of low energy consumption electrolyzers capable of oxidizing selectively biomass-based organics instead of water for a dual production of chemicals (paired electrosynthesis). Also, the state-of
