Synergistic Enhancement of Ethanol Oxidation on Pd/Ce₂Ti₂O₇-TiO₂ via Multiorbital (p-d-f) Interactions.

ABSTRACT: Ethanol oxidation reaction (EOR) is a key component of direct ethanol fuel cells (DEFCs). However, due to its slow kinetics, EOR remains a significant challenge, leading to an increasing search for low-cost, efficient, and stable catalysts. Herein, palladium (Pd) nanostructured catalysts supported on titanium dioxide (Pd/TiO₂) and cerium titanate (Pd/Ce₂Ti₂O₇-TiO₂) were prepared for EOR. The Pd/Ce₂Ti₂O₇-TiO₂ catalyst exhibits superior electroactivity toward the EOR, demonstrating a high mass activity of 2.70 and 2.63-fold relative to Pd/TiO₂ and Pd/C, respectively. The enhanced behavior was attributed to the bifunctional mechanism, improved electron transport, and downshifted d-ban
