CollapseDescription

Electrochemistry (solid-state and solution): characterization of electrocatalysts for solid oxide fuel cells and direct methanol fuel cells in half-cell and single-cell configurations. Techniques: impedance spectroscopy, current-potential polarization measurements, cyclic voltametry, chronoamperometry, and conductivity by 2- and 4-probe methods. Synthesis of multi-atomic oxide materials by soft chemistry methods: non-alkoxide sol-gel synthesis, conventional sol-gel chemistry, aerogel and xerogel processing, Pechini synthesis, co-precipitation routes, and cryogenic deposition. Materials processing: development of novel electrodes, thick and thin film fabrication by colloidal spray deposition and slurry coating techniques, dense electrolyte films and porous electrode fabrication, and deposition of metal nanoparticle catalysts by electrodeposition and impregnation methods. Physical characterization: gas-phased heterogeneous catalysis, powder X-Ray diffraction, Reitveld refinement, SEM/EDX, XPS, TGA/DSC, N2 physisorption (BET/BJH methods), Raman spectroscopy, dynamic light scattering, FT-IR, small-angle neutron scattering, chromatography, and mass spectrometry.

CollapseAccomplishments

Highlights:

I am currently a postdoctoral researcher at the Naval Research Laboratory working with Drs. Debra Rolison and Jeffrey Long developing new electrode materials for direct methanol fuel cells, water oxidation catalysts, electrochemical capacitors, and Li-ion insertion batteries. As a graduate student at the University of California, Davis I held a Student Employee Graduate Research Fellow at Lawrence Livermore National Laboratory (LLNL). My graduate advisor was Professor Susan M. Kauzlarich and at LLNL I collaborate with Drs. Joe H. Satcher and Robert S. Glass. My graduate work focused on the application of nanomaterials to solid oxide fuel cell composite cathodes, specifically sol-gel synthesis and characterization of Y2O3-stabilized ZrO2 and (La1-xSrx)MnO3. In addition, I have prepared and characterized single cell SOFCs and cathode half-cells (3-electrode) in order to study the effects high surface area starting materials have on electrode fabrication, microstructure, and electrochemical performance.

CollapseResponsibilities

I developed lightweight, flexible, electrodes comprising nanoscale coatings of RuO2 deposited on glass filter paper. The electrodes were characterized for electrical properties, morphology, and electrocatalytic activity and were converted into mixed electron-proton conductors by atmospheric treatment. Additionally, I electrochemically deposited Pt nanoparticles on the RuO2 network resulting in an electrode with activity for methanol oxidation. I have also synthesized Au on Gd-doped-CeO2 nanoarchitectures for CO oxidation and water-gas-shift (WGS) catalysts and demonstrated that the pore-solid architecture plays a critical role in catalytic activity with improved performance observed for nanoarchitectures with long-range pore-solid networks (aerogels).
