Synthesis of Nanostructured PdMo Electrocatalysts for Oxygen Reduction Reaction in Fuel Cells

Abstract:

Carbon black supported Pd-Mo bimetallical nanoparticles are prepared by Strong Electrostatic Adsorption (SEA) method. A series of Pd-Mo catalysts were prepared by selective deposition of the [Pd (NH₃)₄]⁺² cationion onto the supported MoO₃ phase. The prepared materials are characterized by N₂-BET, powder XRD and STEM. The results showed that good dispersion of bimetallic nanoparticles on the carbon support is observed from STEM images. Oxygen reduction measurements performed by linear sweep voltammetry indicat the good catalytic activity of Pd-Mo by SEA compared to dry impregnation (DI) bimetallic catalysts since the SEA technique produced more well dispersed and intimately designed bimetallic particles after reduction.
