Fe, Co, and Ni Ions Promote the Catalytic Activity of Amorphous Molybdenum Sulfide Films for Hydrogen Evolution

Xile Hu, Heron Vrubel, Stéphane Fierro, Daniel Andreas Merki, Lorenzo Rovelli

Molybdenum sulfide materials had been shown as promising non-precious catalysts for hydrogen evolution. This paper describes the study of the promotional effect of certain transition metal ions on the activity of amorphous MoS3 films. Ternary metal sulfide ...

Electrochemical promotion of RuO2 catalysts for the combustion of toluene and ethylene

Christos Comninellis, Ivan Bolzonella

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 ...

Relation between potential and catalytic activity of rhodium in propylene combustion

Christos Comninellis, György Foti, Ivan Bolzonella

The relation between the catalyst potential and the catalytic performance has been investigated in the gas-phase combustion of propylene with oxygen over rhodium catalysts at 375 DegC. The rhodium catalyst, deposited on yttria-stabilized zirconia (YSZ) sol ...

Transient behavior of electrochemical promotion of gas-phase catalytic reactions

Christos Comninellis, György Foti, Ivan Bolzonella

Electrochem. promotion (EP) of gas-phase catalysis with O2--conducting solid electrolytes is addressed. The behavior of the ref. electrode, prepd. by deposition of a gold film, was found to be quasi-reversible, 12O2/O2- being the potential detg. redox coup ...

Electrochemical promotion of bipolar electrodes: an estimation of the current bypass

Christos Comninellis

Two methods for the estn. of the current bypass in solid state electrochem. are presented. The current bypass was estd. from the current-voltage curves of a tubular cell with one bipolar element and from the current-voltage curves of a monolith with severa ...

Electrochemical promotion of RuO2-catalysts for the gas phase combustion of C2H4

Christos Comninellis

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 ...

Electrochemical promotion of ruthenium oxide catalysts for the gas phase combustion of ethylene

Christos Comninellis

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 ...
