AC electrical conductivity of CeO2 catalyst samples containing 5, 10 and 20wt% SnO2
prepared by co-precipitation and of SnO2 and CeO2 pure oxides (prepared under the same …

Hexagonal boron nitride (BN), with a graphite-type structure and with surface area of
184m2/g was used as a support for palladium oxide (PdO/BN). About 1wt% of palladium …

The changes of the electrical properties of semiconductor oxide catalysts, when measured in
situ provide useful information about surface processes as adsorption/desorption/reaction …

Two high surface areas BN powders have been prepared to be used as supports for
palladium catalysts in propylene oxidation. Two different precursors originating from …

Changes of electrical properties of dry and wet γ-Al2O3 surface during interaction with a
propylene–air mixture was studied in situ, by following a standard protocol of experiments …

The in situ electrical properties and the catalytic activity of copper ferrite obtained by co-
precipitation and thermal decomposition of polynuclear coordination compounds were …

The surface of six different grades of commercial sub-micron high purity α-Al 2 O 3 powders
produced by two different processes, in-situ chemical vapor deposition (“A” powders), and …

Non-Arrhenius thermal dependence of surface conductance has previously been observed
in the transition-metal oxides TiO 2 and MoO 3. Through the application of thermochemical …

The synthesis of vanadium oxide systems (with 5 and 20 wt% V< sub> 2 O< sub> 5
loadings) supported on commercial γ-alumina was carried out by a wet impregnation …

The catalytic activity of hematite (α-Fe2O3) was studied in deep propane oxidation. Propane
conversion to CO2 was more than 90% at 400oC in excess of oxygen. The AC electrical …
