SHAPE TAILORED ORDERED PDCU₃ NANOPARTICLE SURPASSING THE ACTIVITY OF STATE-OF-THE-ART FUEL CELL CATALYST

摘要

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).
