Electrochemical promotion of CO combustion over Pt/YSZ under high vacuum conditions

Christos Comninellis, Wolfgang Harbich, György Foti, Yuehui Li, Cyril Falgairette, Chun Xia

Electrochemical promotion of CO combustion over Pt/YSZ was investigated under high vacuum conditions. A galvanostatic step was coupled to mass spectrometric gas analysis using an electrochemical mass spectrometric monitoring device. Non-Faradaic electroche ...

Electrochemical promotion of CO combustion over non-percolated Pt particles supported on YSZ using a novel bipolar configuration

Christos Comninellis, Wolfgang Harbich, György Foti, Michael Hugentobler, Chun Xia

The electrochemical promotion of CO combustion over nano-dispersed Platinum particles supported on yttria stabilized zirconia (YSZ) is investigated at 300 degrees C under high vacuum conditions. By polarizing the nanoparticles, we were able to enhance the ...

Investigation of the "permanent" electrochemical promotion of catalysis (P-EPOC) by electrochemical mass spectrometry (EMS) measurements

Christos Comninellis, Cyril Falgairette, Chun Xia

The phenomenon of electrochemical promotion of catalysis (EPOC) is most often fully reversible. Subsequent to long-lasting polarization, however, the new steady-state open-circuit catalytic activity after current interruption may remain significantly highe ...

Solid electrochemical mass spectrometry (SEMS) for investigation of supported metal catalysts under high vacuum

Christos Comninellis, Wolfgang Harbich, Cyril Falgairette, Chun Xia

A new experimental set-up, coupling electrochemistry and mass spectroscopic techniques, for the investigation of a solid electrochemical cell under high vacuum conditions (HV) is presented. Two configurations are realized allowing the investigation of both ...

Investigation of the Pt/YSZ interface at low oxygen partial pressure by solid electrochemical mass spectroscopy under high vacuum conditions

Christos Comninellis, Wolfgang Harbich, György Foti, Cyril Falgairette, Chun Xia

The Pt/YSZ interface was investigated at low oxygen partial pressure under high vacuum (HV) conditions at 400 A degrees C. Two different electrochemical techniques were coupled to mass spectrometric gas analysis using a new solid electrochemical mass spect ...

Quantifying electrochemical promotion of induced bipolar Pt particles supported on YSZ

Christos Comninellis, Wolfgang Harbich, Yuehui Li, Michael Hugentobler, Chun Xia

Electrochemical promotion (EP) of CO oxidation is shown for the first time on induced bipolar Pt particles supported on yttria-stabilized zirconia (YSZ). These Pt particles are formed by sputter deposition of high-purity Pt metal followed by sintering. Con ...
