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 ...

Metal Clusters on Surfaces : Morphology, Stability and Reactivity

Michael Hugentobler

The morphology, stability and reactivity of nanometre-sized particles (Au, Pt) is investigated on three different supports. Gold nanoparticles with a diameter comprised between 4 and 6nm are stabilized in nanosized pits of well defined depth in highly orie ...

Quantifying electrochemical promotion of induced bipolar Pt particles supported on YSZ

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

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 ...
