  • Platinum supported on a mixed metal oxide, NbRu{sub y}O{sub z} (8Nb:1Ru), was evaluated as an electrocatalyst for the ethanol oxidation reaction (EOR) in 0.1 M HClO{sub 4} and 1 M KOH. The support was synthesized from a liquid precursor solution of metal chlorides that was aerosolized and thermally decomposed into a powder via the spray pyrolysis (SP) process. Two samples were of primary interest: 30%Pt deposited onto the support by dry impregnation and 60%Pt as part of the precursor solution that underwent in situ SP Pt dispersion. TEM, SEM, and XRD were used to confirm morphology and deposition of Pt.more » XPS and XAS studies confirmed elemental distribution and oxidation state of Pt catalyst. In situ IRRAS studies in 0.1 M HClO{sub 4} show that these electrocatalysts are capable of facilitating the complete oxidation pathway of EOR, involving scission of the C-C bond and CO oxidation.« less

  • In hitherto existing formate-air fuel cells KOH is used as the supporting electrolyte and KCOOH as the fuel which is oxidized. The investigations in hand were undertaken to decide whether NaOH is also a suitable supporting electrolyte. At the same time, the influence of the addition of carbonate on the rate of the anodic oxidation of the formate was studied. Results are presented graphically.
  • The effect of alkali and alkaline-earth element additives on the properties of V-P-O catalysts was investigated. In entering the lattice of the basic phase of vanadyl pyrophosphate, they act as electron donors, increasing the effective negative charge on the oxygen atom and facilitating cleavage of a proton from the paraffin molecule, which increases the oxidation rate. A simultaneous increase in the surface acidity due to diffusion of phosphorus causes an increase in selectivity. At the same time, perturbations of the structure of pyrophosphate on addition of the additives (determined by the concentration and radius of the added ion) decrease themore » selectivity of the process. Elements with a small ionic radius in low concentrations in the basic composite are most promising for modification of the properties of V-P-O catalysts.« less
  • In this paper, we present a study of a series of carbon-supported Pd-Sn binary alloyed catalysts prepared through a modified Polyol method as anode electrocatalysts for direct ethanol fuel cell reactions in an alkaline medium. Transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and aberration-corrected scanning transmission electron microscopy equipped with electron energy loss spectroscopy were used to characterize the Pd-Sn/C catalysts, where homogeneous Pd-Sn alloys were determined to be present with the surface Sn being partially oxidized. Among various Pd-Sn catalysts, Pd{sub 86}Sn{sub 14}/C catalysts showed much enhanced current densities in cyclic voltammetric and chronoamperometric measurements,more » compared to commercial Pd/C (Johnson Matthey). The overall rate law of ethanol oxidation reaction for both Pd{sub 86}Sn{sub 14}/C and commercial Pd/C were also determined, which clearly showed that Pd{sub 86}Sn{sub 14}/C was more favorable in high ethanol concentration and/or high pH environment. Density functional theory calculations also confirmed Pd-Sn alloy structures would result in lower reaction energies for the dehydrogenation of ethanol, compared to the pure Pd crystal.« less
