The chemical and electrochemical promotion of highly dispersed nanofilm Rh catalysts (dispersion: about 10 %, film thickness: 40 nm) has been investigated for the first time. To this end Rh metal was sputter-deposited, either on a purely ionic conductor (8 ...
The subject of this work is the study of the electrochemical promotion of catalysis (EPOC), also called non-Faradaic electrochemical modification of catalytic activity (NEMCA). In this phenomenon, application of small currents or potentials on catalysts in ...
In this thesis, the electrochemical promotion of lr and Rh based catalysts was studied for the complete combustion of ethylene and propylene. The study was performed by using two types of electrocatalytical cells: a classical, pellet type cell and a tubula ...
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 ...
The method and app. for carrying out electrochem. promoted catalytic reactions, i.e., catalytic reactions where the catalytic rate and selectivity is modified by applying an elec. current or potential between the porous catalyst film which is deposited on ...
A SOFC, with a solid electrolyte layer and at least one anode layer constituting a stratified structure. The anode layer incorporates a twice substituted lanthanide chromite, substituted by Sr on A sites and by Ni or Cu on B sites. The stratified structure ...
A review is given on the so-called electrochem. promotion (EP) denoting an elec. controlled modification of the activity and/or selectivity of a heterogeneous catalyst. Efficient EP in dispersed catalyst systems can be achieved using porous solid-electroly ...
Stress-induced changes in the imprint and switching behavior of (111)-oriented Pb(Zr,Ti)O-3 (PZT)-based capacitors have been studied using piezoresponse force microscopy. Visualization of polarization distribution and d(33)-loop measurements in individual ...
We studied polarization switching of 295 nm thick -oriented-Pb(Zr0.45Ti0.55)O-3 (PZT) thin-film capacitors through a polarization hysteresis loop and piezoelectric force microscopy (PFM) on top of the Pt electrode. Positive voltage pulses of 450 kV/cm ...
The aim of this work was to operate the steam reforming of methanol and the total oxidation of methanol in a microstructured two-passage reactor. The steam reforming enables the production of hydrogen at relatively low temperatures (250 °C) with only a sma ...
