¨ 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.
