Title (EN) SHAPE TAILORED ORDERED PDCU3 NANOPARTICLE SURPASSING THE ACTIVITY OF STATE-OF-THE-ART FUEL CELL CATALYST
(FR) NANOPARTICULE DE PDCU3 ORDONNÉE DE FORME ADAPTÉE SURPASSANT L'ACTIVITÉ D'UN CATALYSEUR DE PILE À COMBUSTIBLE DE L'ÉTAT DE LA TECHNIQUE
Abstract:
(EN) The present disclosure relates to a method of synthesizing shape tailored ordered intermetallic nanomaterials, PdCu3 and its application as electrocatayst in fuel cells. More particularly, the present disclosure relates to a synthesis of ordered PdCu3 nanomaterial starting from a spherical nanocrystal with crystallographically exposed (111) plane to a cubic nanocrystal with (100) plane, and its excellent efficiency as both cathode and anode material, surpassing the activity and stability of the state-of-the-art Pt/C electrocatalyst. The present disclosusre further relates to the unique, cost-effective way of synthesizing ordered Pd based nanocrystal in different shapes with different exposed crystallographic planes for catalysis. The present disclosure also relates to fuel cell device fabrication and applications of said nanomaterial as bi-functional electrode material (active as both anodic and cathodic electrode material).
(FR) La présente invention concerne un procédé de synthèse de nanomatériaux intermétalliques ordonnés de forme adaptée, un PdCu3 et son application en tant qu'électrocatalyseur dans des piles à combustible. Plus particulièrement, la présente invention concerne une synthèse de nanomatériau de PdCu3 ordonné à partir d'un nanocristal sphérique avec un plan exposé cristallographiquement (111) à un nanocristal cubique (100) avec le plan, et son excellent rendement en tant que matériau de cathode et d'anode, surpassant l'activité et la stabilité de l'électrocatalyseur Pt/C de l'état de la technique. La présente invention concerne en outre la manière unique et rentable de synthétiser un nanocristal à base de Pd ordonné dans différentes formes avec différents plans cristallographiques exposés pour la catalyse. La présente invention concerne également la fabrication de dispositif de pile à combustible et des applications dudit nanomatériau en tant que matériau d'électrode bifonctionnel (actif en tant que matériau d'électrode d'anode et de cathode).
