| Description
| - Studie poskytuje první důkaz a popis elektrokatalytické redukce kyslíku na polarizovaném rozhraní voda/1,2-dichloretan (DCE) in situ vyloučenými částicemi Pt. Elektrochemický proces zahrnující redukci kyslíku ve vodné fázi dekamethylferocénem (DCMFc) jako donorem elektronu v DCE je studován v širokém rozpětí mezifázových potenciálových rozdílů ve vodném prostředí pH (3-10). Pt částice jsou na mezifází deponovány redukcí tetrachloroplatnatanu amonného ve vodné fázi tímtéž elektronovým donorem ve fázi organické. Je prokázáno, že rovnice difúzního transportu ireversibilní mezifázové redukce kyslíku spřažené s reversibilní partiční rovnováhou kyslíku mezi vodnou a DCE fázemi, mohou být řešeny na základě konvolučního principu. Konvoluční analýza voltamogramů umožňuje v celkové reakci přenosu elektronu úvahu o její stechiometrii a určení kinetických parametrů (Tafel plots). (cs)
- We present first evidence and evaluation of electrocatalysis of the interfacial oxygen reduction at the polarised water vertical bar 1,2-dichloroethane (DCE) interface by in situ deposited Pt particles. The electrochemical process involves the reduction of oxygen in the aqueous phase by decamethylferrocene (DCMFc) as an electron donor in DCE, and is investigated in a broad range of interfacial potential differences and the aqueous solution pH (3-10). The Pt particles are deposited at the interface by reducing ammonium tetrachloroplatinate in the aqueous phase by the same organic-phase electron donor. It is shown that the diffusion equations for an irreversible interfacial oxygen reduction coupled with the reversible partition of oxygen between the aqueous and DCE phase can be solved by using the convolution principle. Convolution analysis of voltammograms makes it possible to consider the stoichiometry of the overall electron transfer reaction, and to infer kinetic data (Tafel plots).
