The reaction rate, the catalyst potential, the catalyst work function and the voltammetric charge were in situ measured during a galvanostatic transient of ethylene combustion on an IrO2 catalyst at 380 Deg. The catalytic activity of an IrO2 catalyst could ...
The electrochem. promotion of RuO2 catalysts interfaced with yttria stabilized zirconia was studied for the combustion of ethylene. The complete oxidn. of ethylene can be described by an Eley-Rideal type mechanism. In situ work function measurements were u ...
A model for the electrochem. promotion induced by electrochem. generated promoting species is proposed. The formation rate of promoters is assumed to be proportional to the availability of free surface sites at the solid electrolyte/catalyst/gas three-phas ...
The electrochem. promotion of the complete catalytic oxidn. of ethylene and toluene on RuO2Catalyst films deposited on Y2O3-stabilized-ZrO2 (YSZ) was studied at temps. 400 to 500 Deg. Anodic polarization (1.5 V), i.e. O2- supply from the YSZ support to the ...
In this paper the electrochem. promotion of RuO2 catalyst was studied for the oxidn. of C2H4 to CO2 and H2O. The reaction rate can be increased of up to a factor of 115 by anodic polarization. A kinetic model for the simulation of the open circuit reaction ...
The catalytic activity for the gas phase combustion of ethylene of an IrO2 film, used as electrode in a solid electrolyte cell, can be increased by polarizing the metal-solid electrolyte interface. The catalytic activity remains higher even after current i ...
In the attempts to attain greater efficiency of mobility, based in the long-term on renewable energy sources, the efficiency of energy conversion in the vehicle remains an important issue. Polymer electrolyte membrane fuel cell technology has the potential ...
The catalytic activity of IrO2 catalyst used as an electrode on a YSZ solid electrolyte cell for the gas phase combustion of ethylene can be increased by electrochem. pre-treatment. Thus, the polarization of the IrO2 electrode for 90 min at 300 mA, relativ ...
The influence of the polarization of the RuO2/YSZ interface on the electrochem. promotion of RuO2 catalysts was studied by temp. programmed desorption and high temp. cyclic voltammetry measurements. The desorption activation energy of adsorbed oxygen decre ...
The electrochem. oxidn. (or combustion) of orgs. with simultaneous oxygen evolution has been investigated using different oxide electrodes. A simplified mechanism for the electrochem. oxidn. of orgs. is presented, according to which selective oxidn. occurs ...
