Ozone prodn. in 5M H2SO4 with Ti/IrO2/SnO2 - Sb2O5 electrodes was studied. Electrodes were prepd. at 550 Deg by spray pyrolysis of a soln. of precursors contg. tin and antimony chlorides. The aim of this work was to elucidate the mechanism of activation an ...
The performance of the electrolytic ozone generation using a solid polymer electrolyte (SPE) and Pb anode is described. This anode has been prepd. by application of Pb powder on a porous Ti substrate coated with IrO2 layer (Ti/IrO2/Pb anode). Electrochem. ...
Rotation anisotropy by second harmonic generation (SHG) is carried out on epitaxial Hg1−xCdxTe (MCT) and oxide- and sulphide-covered MCT surfaces and shows the fourfold symmetry pattern expected from the {100} surface (C4v symmetry). The uneven nature of t ...
The electrochem. behavior of synthetic B-doped diamond thin-film electrode (BDD) was studied in acid media contg. 4-chlorophenol (4-CP) by cyclic voltammetry, chronoamperometry, and bulk electrolysis. The results showed that in the potential region of supp ...
Among the numerous base metals tested for DSA type electrodes (e.g., titanium and its alloys, zirconium, niobium etc.), tantalum is a potentially excellent substrate owing to its good elec. cond. and corrosion resistance, and the favorable dielec. properti ...
IrO2 and boron-doped diamond electrodes were tested by preparative electrolysis of simple model compds. in acid medium. In oxidn. reactions of more complex mechanism than simple electron transfer, these electrodes are active only at potentials of simultane ...
Several bottom electrode systems for ferroelectric thin film deposition onto reactive substrates or reactive metal films have been investigated with respect to chemical barrier properties and contact resistivity. Such electrode systems should not deteriora ...
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 catalytic activity of an IrO2 catalyst used as an electrode on a YSZ solid electrolyte cell for the gas-phase combustion of ethylene can be increased by electrochem. pretreatment. Thus, the polarization of the IrO2 electrode during 90 min at 300 mA, re ...
Electrochem. oxidn. of orgs. at thermally prepd. dimensionally stable metal oxide anodes (DSA) has been studied. In reactions involving only simple electron transfer, oxide electrodes exhibit an electrocatalytic activity similar to that of noble metal elec ...
