Abstract

Spray pyrolysis of metal precursors was used to synthesize binary and ternary nano-structured Pt-based catalysts. Characterization of the catalysts was performed using SEM, TEM, and EDS to determine morphology, purity and composition. The electrochemical performance of synthesized Pt ₈₄Ru ₁₆, Pt ₉₆Sn ₄, and Pt ₈₈Ru ₆Sn ₆ was evaluated via cyclic voltammetry and steady state polarization for oxidation of ethylene glycol and glycerol. The binary Pt ₈₄Ru ₁₆ and Pt ₉₆Sn ₄ catalysts had higher maximum currents and better stability than a templated Pt catalyst and templated ternary Pt ₈₈Ru ₆Sn ₆ catalyst. All binary and ternary catalysts had less adsorbed reaction products during potential cycling than the templated platinum electrocatalyst. In situ infrared reflection absorption spectroscopy (IRRAS) analysis showed complete oxidation of ethylene glycol and glycerol with the binary and ternary catalysts by CO ₂ generation. This work emphasizes the benefits provided by adding Ru and Sn to Pt catalysts for oxidation of complex alcohols.
