Electrochemical investigation of ion implanted p-Si
The present work investigates the possibility of selective electrochemical metal deposition on ion implanted p-Si. The idea is that defects introduced into the substrate by ion implantation make it more susceptible to electrochemical reactions compared to ...
EPFL2003Electron transfer kinetics on composite diamond (sp3)-graphite (sp2) electrodes
Christos Comninellis, Ilaria Duo
The concept of non-diamond sp2 impurity states as charge transfer mediators on boron-doped diamond (BDD) surface was suggested as an explanation for the electrochem. behavior of synthetic diamond-based electrodes. To verify this concept, graphite particles ...
2003Electrochemical Investigation of Traps in a Nanostructured TiO2 Film
Electron traps at the nanostructured TiO2 (anatase)/aq. electrolyte interface were studied by electrochem. methods. The transient current decays at different potentials pos. of the flatband potential clearly illustrate the trap-filling process. The more ne ...
2001Interfacial electron transfer in dye sensitised nanocrystalline TiO2 films
Sub-picosecond transient absorption study has been employed to study the electron transfer kinetics in the dye-sensitized TiO2 films used in commercial photovoltaic devices. The electron injection in these dye sensitized films occurs on an ultrafast time s ...
Bangalore1997Oxydation électrochimique du phénol sur des électrodes du type métal support/dépôt conducteur
Electrochemistry can bring important contributions to current applications, such as organic synthesis or wastewater treatment. In an environmental context, electrochemical processes are interesting substitutes to the conventional wastewater treatment techn ...
EPFL1996Use of Zr/ZrO2 as a counter electrode for the minimization of loss reactions in single compartment electrolysis cells
A preliminary study was made of the cathodic properties (redn. of Ce(IV) and hydrogen evolution) of ZrO2 layer formed on Zr by thermal decompn. at high temp. Zr was chosen as base metal due to the fact that this valve metal is stable under conditions of hy ...
1994The electrochemical reduction of anthraquinone to anthrone in concentrated sulfuric acid
The chem. redn. of anthraquinone(I) has at least 2 disadvantages on the industrial scale; therefore, an electrochem. method was developed. The electrochem. redn. of I is done in a 2-compartment cell using concd. H2SO4 (15-17 mol/dm3) as the electrolyte at ...
1985Sulfur Poisoning Recovery on a Solid Oxide Fuel Cell Anode Material through Reversible Segregation of Nickel
Jan Van Herle, Davide Ferri, Oliver Kröcher, Hossein Madi, Andre Heel
The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni catalyst f ...
