Electron Transfer Kinetics on Boron-Doped Diamond Part I: Influence of Anodic Treatment

Christos Comninellis, Ilaria Duo

Boron-doped diamond electrodes, both as-grown and polarized anodically under different conditions, were prepd. in order to study the chem. and electrochem. changes of diamond and clarify the role played by the surface-state d. Many different treatments wer ...

Electrochemical incineration of chloranilic acid using Ti/IrO2, Pb/PbO2 and Si/BDD electrodes

Christos Comninellis

The electrochem. oxidn. of chloranilic acid (CAA) was studied in acidic media at Pb/PbO2, B-doped diamond (Si/BDD) and Ti/IrO2 electrodes by bulk electrolysis expts. under galvanostatic control. The obtained results have clearly shown that the electrode ma ...

Carbon-carbon bond cleavage of 1,2-diphenyl-ethanes in CH3OH-H2SO4-H2O electrolyte on a boron-doped diamond (BDD) electrode has been investigated electrode using 1,2-di-(p-tert-butylphenyl)-ethane and 1,2-dimethoxy-1,2-di-(p-tert-butylphenyl)-ethane as mod ...

2004

The methoxylation of p-tert-butyltoluene (TBT) in CH3OH-H2SO4-H2O soln. has been investigated on graphite and boron-doped diamond (BDD) anodes. Different reaction intermediates have been found on BDD and graphite. In fact BDD electrodes favor the formation ...

2004

Diamond films with different levels of doping have been the subject of applications and fundamental research in electrochemistry, opening up a new branch known as the electrochemistry of diamond. The electrochemical properties of diamond mostly depend on t ...

Biosystem for the culture and electrical characterisation of epithelial cell tissues

Serge Hediger

The aim of this work was to develop a microchamber system for performing electrophysiological measurements on epithelial surface on culture membranes in the mm2 range. This miniaturised system permits the use of small quantities of epithelial cells, which ...

EPFL2002

The Boron-Doped Diamond (BDD) electrode is a new electrode material with high stability, even at high anodic potential. Furthermore BDD is not prone to fouling. Due to these properties, BDD can provide new opportunities in electrochem. synthesis of org. an ...

Electrochemical generation of silver(II) at boron-doped diamond electrodes

Christos Comninellis, Pierre-Alain Michaud, Ilaria Duo, Marco Panizza

Synthetic boron-doped diamond (BDD) thin film electrodes were tested for the electrogeneration of silver(II). In nitric acid, the kinetics of the silver(I)/silver(II) couple were studied by cyclic voltammetry. The results demonstrate that silver(II) can be ...

Electrocatalysis in anodic oxidation of organics with simultaneous oxygen evolution

Christos Comninellis

The electrochem. oxidn. (or combustion) of orgs. with simultaneous oxygen evolution was studied using different electrode materials (Ti/IrO2, Ti/SnO2). A simplified mechanism for the electrochem. oxidn. of orgs. is presented, according to which selective o ...
