My primary interest is the synthesis and characterization of new inorganic materials which may find use in alternative energy or energy-saving applications. We are currently focusing on doped transition metal oxides as potential cathode supports in fuel cells. In addition we are researching new oxide and oxynitride luminescent materials for use in solid-state lighting, and also synthesizing new nitride compounds using lithium nitride as a flux.
Durable materials are essential to the widespread introduction of fuel cell technology. A key challenge in the manufacture of stable polymer electrode membrane (PEM) fuel cells is corrosion of the carbon black cathode supports. Carbon black reacts to form CO2 at high potentials, often achieved during start-up and shut-down conditions. New materials that could replace carbon black are transition-metal-doped titanium and tin dioxides. The rutile structure exhibits excellent flexibility in doping it with transition metals such as tungsten. Titanium dioxide (TiO2) and tin dioxide (SnO2) are two rutile-type compounds that are stable and inexpensive, but non-conducting. We make TiO2 and SnO2 conducting by substituting tungsten, molybdenum and other transition metal cations in place of some of the titanium or tin cations. Substituted compounds with stoichiometries Ti1-x-y AxByO2, (where A = W, Mo, Ta, Nb, and B = V, Cr, Mn, Fe, Co, Ni) have been synthesized using chemical vapor transport (CVT). Many of the substituted oxides maintain the rutile structure, are conducting, and are stable in acid solutions. We're currently synthesizing doped tin oxides using CVT and sol-gel methods. We characterize our compounds by powder X-ray diffraction, X-ray fluorescence and by resistivity measurements. Our goal is stable, electrically conducting materials that will be useful for a wide variety of applications such as cathode supports in fuel cells.
