Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...
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 ...
The surface properties and the electrochem. behavior of a fluorinated B-doped diamond (F-BDD) electrode prepd. by plasma treatment in CF4-He mixt. was studied by XPS and cyclic voltammetry in acidic media. The results showed C-F bonding (C-CF and C-F) on t ...
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 ...
A novel electrochemiluminescence (ECL) detector is presented in this article. The detector is applied for micellar electrokinetic chromatographic separation of dichlorotris(2,2′-bipyridyl)ruthenium(II) hydrate [Ru(bpy)] and dichlorotris(1,10-phenanthroline ...
The cathodic properties are discussed of a ZrO2 layer formed on Zr by thermal treatment and by anodic oxidn. The electrosynthesis of ammonium peroxydisulfate (2SO42- .dblarw. S2O82- + 2e-) for which the cathodic redn. of persulfate to sulfate is the undesi ...
The charging kinetics of viologen-TiO2 displays was studied by electrochem. techniques. Resistive and capacitive effects were analyzed in terms of a simple model for the charging kinetics in optical switches. For large-segment devices the model resistance ...
Electrochem. insertion of lithium in nanoporous and CVD samples of anatase was studied by chronoamperometry. The currents following cathodic and anodic potential steps were monitored as a function of film thickness, temp., and electrolyte concn. The time d ...
The electrochem. oxidn. of phenol for wastewater treatment was studied on doped SnO2 anodes. Anal. of reaction intermediates and a C balance showed that the main reaction is oxidn. of phenol to CO2. This unexpected behavior of the SnO2 anode is explained b ...
The use of ZrO2 membrane on counter electrodes (e.g. Zr) is proposed for controlling the mass transfer rates to the electrode and therefore the extent of possible loss reactions. A comparative study was undertaken to examine the influence of the prepn. tec ...
