Interfacial Electronic Interactions within the Pd-CeO₂/Carbon Onions Define the Efficient Electrocatalytic Ethanol Oxidation Reaction in Alkaline Electrolytes.

ABSTRACT: Porous Pd-based electrocatalysts are promising materials for alkaline direct ethanol fuel cells (ADEFCs) and ethanol sensors in the development of renewable energy and point-of-contact ethanol sensor test kits for drunk drivers. However, experimental and theoretical investigations of the interfacial interaction among Pd nanocrystals on supports (i.e., carbon black (CB), onion-like carbon (OLC), and CeO₂/OLC) toward ADEFC and ethanol sensors are not yet reported. This is based on the preparation of Pd-CeO₂/OLC nanocrystals by the sol-gel and impregnation methods. Evidently, the porous Pd-CeO₂/OLC significantly increased membrane-free micro-3D-printed ADEFC performance with a high peak power density (P_max = 27.15 mW cm^-2) that is
