The main electroreduction products were formic acid, methanol, formaldehyde, carbon monoxide and methane, while undesired hydrogen gas by-product was also detected [120]. 28 Electrochemically Enabled Sustainability A special type of gas diffusion membrane (GDM) was coated with Pt or Pd nanoclusters, and showed enhanced properties with respect to commercial materials for the gas-phase electrocatalytic reduction of CO2 to fuels [113]. The proper choice of the membrane to be used in CO2 electroreduction necessitates a circumspect evaluation of membrane properties, so that it complies with the cell operation requirements.

SelemionTM AMV, developed by Asahi Glass Co Engineering, AGC, Japan, Neosepta® AMX by Astom Corporation, USA, and ExcellionTM I-200, SnowPure, LLC, USA); the latter allows for the passage of anionic products, such as formate and acetate ions. 1 mol/dm3 KHCO3 as the anolyte. Alternatively, phosphate buffers can act as the electrolyte. 8. It is important to maintain a gas headspace in both compartments of the cell; the headspace is regulated by a mass flow controller. Prior to this, the electroreduced carbon dioxide should be humidified with water by passing the gas through a bubbler.

Chem. 30). On p-GaP photoelectrochemical electrodes, the same end product, formic acid, is obtained by the direct reduction of the pyridinium radical–CO2 complex [149]. 32). 33), which undergoes a fast reduction with another pyridinium radical to yield methanol (Equation H + N Eq. 31 + H2O C O N OH C H O H H Eq. 32 2 + N N C O + C O N H H H + Eq. 33 C O N N H C H HO H H H Eq. 11 Mechanism of pyridinium-catalysed electrochemical reduction of formic acid to methanol.
