Electrolysis in aq. 1M HClO4 and 1M H2SO4 solns. was carried out under galvanostatic conditions using B-doped diamond electrodes (BDD). Analyses of the oxidn. products showed that in 1M HClO4 the main reaction is oxygen evolution, while in H2SO4 the main r ...

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 ...
The present work deals with two subjects. The interaction of NO2 and HONO with different types of soot are examined in the first part whereas in the second part an experimental set-up is presented which has been built in order to measure the kinetics of th ...
The electrochem. oxidn. of Mn(II) in H2SO4 (30% wt.) has been studied using cyclic voltammetry. The mechanism was shown to be of the type ECE (Electrochem.-Chem.-Electrochem.). The deposition of MnO2 on the anode can be avoided by inhibiting the chem. reac ...
Title compds. I (R = H, C1-4 alkyl or alkoxy), useful as dye intermediates, are prepd. by oxidn. of nitronaphthalenes with Mn2(SO4)3. A melt contg. 173 parts 1-nitronaphthalene was treated over 30 min with 2200 parts of an aq. 36% Mn2(SO4)3-H2SO4 soln. whi ...
A report from a symposium describing the electrochem. oxidn. of arom. hydrocarbons to benzoquinones with Mn2(SO4)3 in concd. H2SO4. A simple reactor for the electrochem. regeneration of Mn3+ from Mn2+ is also described. [on SciFinder (R)] ...
The electrochem. prepn. of ceric sulfate [13590-82-4] was studied in concd. H2SO4 (10 mol/dm3). The current efficiency of the reaction increases considerably if a mixed catalyst (Ag2SO4 + MnSO4) is used. [on SciFinder (R)] ...
The loss of current efficiency in the indirect 2-stage electrochem. process using the Mn2+/Mn3+ system is due to the oxidn. of orgs. present in the recycled electrolyte. There is no evidence of electrode poisoning under the exptl. conditions studied (88% H ...
The chem. redn. of anthraquinone(I) has at least 2 disadvantages on the industrial scale; therefore, an electrochem. method was developed. The electrochem. redn. of I is done in a 2-compartment cell using concd. H2SO4 (15-17 mol/dm3) as the electrolyte at ...
