Nafion-assisted deposition of microemulsion-synthesized platinum nanoparticles on BDD

Christos Comninellis, Guillaume Siné

Pt nanoparticles were synthesized by the H2O-in-oil (w/o) microemulsion technique and deposited onto B-doped diamond (BDD) electrodes. TEM showed that Pt particles size is limited to 2-5 nm range with narrow distribution. Anodic treatment at high overpoten ...

Electrochemical promotion of catalysis

Christos Comninellis, György Foti, Ivan Bolzonella

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 ...

Lanthanide chromite-based sofc anodes

Ravindranathan Thampi, Joseph Sfeir

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 ...

Stability and performance of tape cast anode supported electrolyte (ASE) cells.

Jan Van Herle, Raphaël Ihringer

Recent progress in our development of anode supported electrolyte (ASE) SOFcells is reported. The cells are fabricated by cocasting of aqueous slurries of NiO/YSZ and 8YSZ, followed by cofiring. A gradient cathode is deposited by screenprinting successive ...

Electrochemical promotion of catalysis

Christos Comninellis, György Foti, Justyna Eaves, Ivan Bolzonella

A review with refs. concerning electrochem. promotion of catalysis is presented. Recent progress made in our lab. in the field of electrochem. promotion of heterogeneous catalytic gas reactions is presented. The phenomenon consists of non-Faradaic modifica ...

Ceramic Oxygen Separation Membranes and Mixed Conductors

Jan Van Herle, Peter Hugh Middleton, Ferran Marqués

A consortium was created to investigate electroceramic materials that show ionic or mixed ionic-electronic conduction (MIEC), for application as oxygen separation membranes and in solid oxide fuel cells (SOFC, electrolytes and cathodes). The focus is on de ...

Electrochemical promotion of catalysts for gas phase reactions

Christos Comninellis, György Foti

Recent progress made in our lab. in the field of electrochem. promotion of heterogeneous catalytic gas reactions is reviewed. The phenomenon consists of electrochem. polarization of the catalyst/solid electrolyte interface resulting in a dramatic, non-Fara ...

Development of a 100 W rechargeable bipolar zinc/oxygen battery

Christos Comninellis, Christian Schlatter

A bipolar filter press-type elec. rechargeable Zn/O2 battery has been developed. Reticulated copper foam served as substrate for the zinc deposit on the anodic side, and La0.6Ca0.4CoO3-catalyzed bifunctional oxygen electrodes were used on the cathodic side ...

Use of electrocatalytic anodes in photolysis

A photolytic system comprised of a darkened halfcell and an illuminated halfcell in which oxidation and reduction reactions are made to occur. These halfcells are joined by an electrically conductive element and an ion conducting junction for electron tran ...

The preparation and behavior of titanium/gold/plumbic oxide anodes

Christos Comninellis

Ti/Au/PbO2 electrodes were prepd. and their stability in H2SO4 (2-12 mol/dm3) was studied. Incorporation of a Au layer between the Ti substrate and the PbO2 decreases the resistance of the electrode. The corrosion of an anodically polarized electrode incre ...
