In this section, alternative systems to water electrolysis for electrochemical hydrogen synthesis such as conventional alcohols (methanol, ethanol), biosourced polyols (ethylene glycol, glycerol), and saccharides from nonedible biomass are discussed. The importance of the nature, composition, and structure of catalysts and of the reaction medium on the activity and selectivity is presented. It is shown that the control of the electrode potential, catalyst composition, and reaction medium allows tuning the selectivity and increasing the activity, and further to produce simultaneously high purity hydrogen at the cathode of an electrolysis cell and value-added compounds with high selectivity at the anode of the electrolysis cell. |
