The electrocatalytic behaviour of carbon-supported ruthenium oxide electrodes for oxygen evolution and methanol oxidation in acid solutions is reported. Physical characterization of the electrodes by X-ray diffraction, X-ray photoelectron and 99Ru Mossbauer spectroscopies indicated the ruthenium to be present as a mixture of RuIV oxides including the stable rutile phase. Electrochemical studies show that a RuVI species promotes the catalytic oxidation of methanol, whilst surface-bound RuO4 is involved in the oxygen evolution reaction.

A series of binary oxides and SiC whisker reinforced composites both having a matrix composed of an α-(Al, R)2O3 solid solution (R: rare earth) have been studied by analytical electron microscopy (AEM). The mechanical properties of the composites as well as crystal structure, composition, and defects of both second phases and the matrix were investigated. The formation of various second phases, e.g. garnet, β-Alumina, or perovskite structures in the binary Al2O3-R2O3 and the ternary Al2O3-R2O3-SiC(w) systems are discussed.Sections of the materials having thicknesses of 100 μm - 300 μm were first diamond core drilled. The discs were then polished and dimpled. The final step was ion milling with Ar+ until breakthrough occurred. Samples prepared in this manner were then analyzed using the Philips EM400T AEM. The low-Z energy dispersive X-ray spectroscopy (EDXS) data were obtained and correlated with convergent beam electron diffraction (CBED) patterns to identify phase compositions and structures. The following EDXS parameters were maintained in the analyzed areas: accelerating voltage of 120 keV, sample tilt of 12° and 20% dead time.
