Oxidation state and size effects in CoO nanoparticles

Article Abstract:

Surface spectroscopies were used to examine the oxidation state and size effects on the electronic structure of 10 and 20 nm CoO nanoparticles. Results showed that the surface of the as-grown CoO nanoparticles appears to be oxidized up to Co3O4, but annealing in UHV at 600 degrees C reduces the surface to the nominal CoO composition. The surface effects were found to have no significant effect on the electronic structure of the 20 nm CoO nanoparticles, but not in the case of the 10 nm CoO nanoparticles.

Reduction of tin oxide by hydrogen radicals

Article Abstract:

A study was conducted to analyze the effects of a reducing hydrogen ambient on textured tin oxide thin films on glass substrates. U-type SnO2:F transparent conducting oxide layers on glass substrates were utilized. The PASTA deposition system was used to carry out the plasma and hot wire-decomposed H-treatments of the substrates. Experimental findings indicated that hot wire-formed hydrogen radicals resulted in the reduction of textured tin oxide and the formation of tin particles at the surface.

Characterization of V2O5/TiO2-ZrO2 catalysts by XPS and other techniques

Article Abstract:

A study was conducted to characterize the preparation of a high surface area titania-zirconia mixed oxide support through the precipitation from homogeneous solutions. The thermal effects were analyzed by different characterization methods. The Siemens D-500 diffractometer was utilized to obtain x-ray powder diffraction patterns. Results suggested titania-zirconia binary oxide as a promising support material for the dispersion of vanadium oxide.
