Electrochemical CO2 reduction reaction (CO2RR) is a promising route as carbon utilization technique. One of the major challenges to commercialize this technology is the large applied potential needed due to the oxygen evolution reaction (OER) in the anodic half-cell, which reduces the energy efficiency of the system. To decrease the cell applied potential, 5- hydroxymethylfurfural oxidation reaction (HMFOR) toward 2,5-furandicarboxylic acid (FDCA) is proposed to replace the OER and improve the energy efficiency of the electrolytic system. However, a selective, active and stable catalyst for this reaction is lacking in the literature to be coupled with the CO2RR at industrially relevant high current density (e.g., ≥ 100 mA/cm2). In this thesis nickel-phosphorus (Ni-P) catalysts are synthesized and shown to have high Faradaic efficiency (90%) and stability (> 20 h) for the HMFOR. By adopting the active Ni-P as anode catalyst and Sn nanoparticles as cathode catalyst for the CO2RR in a continuous flow cell reactor, high FDCA yield is achieved simultaneously with selective formate production. Moreover, an energy efficiency improvement of near 10% is realized compared to OER as the anode. This continuous CO2RR-HMFOR electrocatalysis scheme is shown to be a stable and energy efficient electrochemical system.

One of the major challenges to commercialize this technology is the large applied potential needed due to the oxygen evolution reaction (OER) in the anodic half-cell, which reduces the energy efficiency of the system.

520 $a La reaction de reduction electrochimique du CO2 (CO2RR) est une voie prometteuse en tant que technique d'utilisation du carbone. L'un des principaux defis pour commercialiser cette technologie est le potentiel applique eleve necessaire en raison de la reaction d'evolution de l'oxygene (OER) dans la demi-cellule anodique, ce qui reduit l'efficacite energetique du systeme. Pour diminuer le potentiel applique a la cellule, la reaction d'oxydation du 5- hydroxymethylfurfural (HMFOR) vers l'acide 2,5-furandicarboxylique (FDCA) est proposee pour remplacer l'OER et ameliorer l'efficacite energetique du systeme electrolytique. Cependant, un catalyseur selectif, actif et stable pour cette reaction fait defaut dans la litterature pour etre couple au CO2RR a une densite de courant elevee pertinente sur le plan industriel (par exemple, ≥100 mA/cm2). Dans cette these, des catalyseurs au nickel-phosphore (Ni-P) sont synthetises et montrent une efficacite faradique elevee (90%) et une stabilite (> 20 h) pour le HMFOR. En adoptant le Ni-P actif comme catalyseur d'anode et les nanoparticules de Sn comme catalyseur de cathode pour le CO2RR dans un reacteur a cellule a flux continu, un rendement eleve en FDCA est atteint simultanement a la production selective de formiate. De plus, une amelioration de l'efficacite energetique de pres de 10% est realisee par rapport a l'OER car l'anode. Ce schema d'electrocatalyse CO2RR-HMFOR en continue s'avere etre un systeme electrochimique stable et econome en energie.
