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 ...
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 ...
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 ...
The Cl2 evolution reaction was studied at highly boron-doped diamond thin film electrodes. The comparison of this carbonaceous material with graphite and glassy carbon points out the similar behavior in terms of diagnostic parameters and related mechanisms ...
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 ...
The service life of SnO2-Sb2O5 coated anodes prepd. by the spray pyrolysis technique using Ti or Ti/IrO2 substrate, was studied under galvanostatic conditions (100 mA cm-2 in 1M H2SO4 at 25 Deg). The presence of an IrO2 interlayer between the Ti substrate ...
The electrochem. behavior of some model org. compds. on boron-doped synthetic diamond thin film electrodes, obtained by HF-CVD on p-Si substrate was investigated. Only reactions involving simple electron transfer like hydroquinone/benzoquinone are active i ...
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 ...
