Surface dynamics in tin-dioxide-containing catalysts II. Competition between

03/08/1995

Deviation from stoichiometry is a general property of oxides, and the defect structures results in semiconducting properties. Anion vacancies are reported as the usual stoichiometric point defects (references 19, 21, and 22).

Electrical conductivity of g-alumina at atmospheric pressure under dehydrating

06/28/2001

Conduction at low temperature is dominated by proton movement by vehicle mechanism, facilitated by molecules of physically adsorbed H2O having high mobility.

Adsorption on transition aluminas from in situ capacitance measurements

12/17/2002

Weak adsorption of water on g-alumina produces an increase in the apparent capacity/relative dielectric constant.

In situ electrical conductivity study of propylene interaction with alumina

02/08/2003

Mobile species (proton vehicles) exist on alumina surface at low temperature.

Water and proton mobility on g-alumina and Sn/g-alumina: A combined electrical

2005

The g-alumina support dictates the surface behavior of SnO2.

Air moisture sensing properties of ZnCr2O4-K2CrO4 composites

ZnCr2O4-K2CrO4 exhibits ion hopping and diffusion processes.

Electrical and catalytic properties of SnO2/TiO2 measured in operando conditions

08/27/2011

By supporting an n-type oxide (SnO2) on an n-type semiconductor support (TiO2), the O2 adsorption and surface oxidation are facilitated by the synergy between the two phases.

Possible dual-charge-carrier mechanism of surface conduction on g-alumina

02/11/2007

Hydrogen-bonded water appears to be the most plausible charge-carrier vehicle for g-alumina at low temperatures, possibly serving as a scaffold to support mobile protons.

Entropic contributions to the atomic-scale charge-carrier/surface interactions

10/24/2009

By comparing best-fit values of the energetic and entropic parameters in the model to those obtained from quantum-chemical electronic structure calculations, one can dramatically reduce the number of candidates for surface charge carriers and their modes of interaction with the surface.

Scurtu

Surface evolution of the Sn-Ce-O powders in various atmospheres

11/10/2011

Sn-Ce-O powders showed catalytic activity for CO oxidation to CO2 at lower temperature (~160 C) due to the synergic effect of the two oxides on the CO oxidation reaction.

Influence of the reactant gas on the electrical properties of alumina-supported

12/06/2011

The activity of SnO2 for propylene oxidation is strongly diminished when it is supported on g-alumina.

Stoica

Protonic conductivity of Pt/Al2O3 in hydrogen- and water-containing atmospheres

08/18/1999

Hydrogen species produced by adsorption on Pt and transferred to the support by hydrogen spillover must be protonic in nature since this process is accompanied by thermal and conductivity effects.
