B-doped diamond films were deposited by large-area hot filament chem. vapor deposition (HFCVD) on Si and different industrial electrode materials, such as Ti, Zr, Nb, Ta, W, and graphite, with areas up to 50 * 60 cm2. B-doping levels ranging from 50 to sev ...
We present a photoemission study on reactivity of the Au-Si system. We studied gold films evaporated atop ultrathin silicon layers previously deposited on GaAs. Following analysis of both the Si 2p core level and the Au 5d valence band spectra related resp ...
The electrochemical promotion of heterogeneous catalytic reactions is a new development which draws the attention of the scientific community as much to fundamental research as to the possible direct applications of this phenomenon in automotive and in ind ...
Synthetic B-doped diamond thin film electrodes were tested for electroanal. detection of 2-naphthol. This redox reaction was studied by cyclic voltammetry in aq. acidic soln. Well-resolved oxidn. waves were obsd. and the voltammetric peaks exhibited naphth ...
This work contributes to the generalization of the Non-faradaic Electrochemical Modification of Catalytic Activity effect, known under the acronym NEMCA. This effect is observed for the first time over an oxide catalyst, namely IrO2 supported on yttria-sta ...
Oxygen and hydrogen peroxide electroredn. on La0.6Ca0.4CoO3 perovskite electrodes was studied in alk. media. Rotating disk electrodes were built using pure powders of the oxide to avoid any side reactions on the catalyst support, e.g. carbon. For O2 redn., ...
The morphol. examn. and the structural anal. of DSA-O2 electrodes [IrO2-Ta2O5 (70:30 mol%) coating] show that at moderate firing temp. (about 550 Deg), sepn. of phases occurs with the formation of agglomerates of IrO2 crystals and amorphous Ta2O5. At highe ...
The electrochem. oxidns. of some org. compds. have shown that only reactions involving simple electron transfer are active on diamond electrodes in the potential region of water stability. For more complex reactions, diamond electrodes show no electrocatal ...
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 ...
