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

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

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 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 ...

A DEMS study of methanol and formic acid oxidation on boron-doped diamond electrode

Christos Comninellis, Agnieszka Kapalka, György Foti

The electrochemical oxidation of methanol and formic acid in 1 M HClO4 is studied on boron-doped diamond electrode using differential electrochemical mass spectrometry (DEMS). DEMS is used to identify products and intermediates of the reaction monitored on ...

Charge storage at Pt/YSZ interface as the origin of 'permanent' electrochemical promotion of catalysis

György Foti

Tuning of the catalytic reaction rate by electric polarization of the interface between an electron conducting catalyst and an ion conducting support, called electrochemical promotion of catalysis (EPOC), is most often fully reversible. Its state-of-the-ar ...

Charge storage at the Pt/YSZ interface

Christos Comninellis, György Foti, Cyril Falgairette, Arnaud Jaccoud

The electrochemical behavior of Pt/YSZ electrodes in oxygen containing atmosphere at 450 A degrees C has been investigated by double-step chronoamperometry and programmed linear sweep cyclic voltammetry. The response of the O-2(g),Pt/YSZ system in these ex ...
