Abstract
Biphasic oxygen reduction and hydrogen evolution are studied for almost two decades, because of favourable overpotential decrease as compared to aqueous solution. Until now, polar solvents (ε > 7) were employed as organic phase in these studies. Here, we applied non polar vegetable oils (rapeseed, linen or sunflower) for biphasic H2O2 generation by oxygen reduction. This product was detected at oil|aqueous acid solution interface by scanning electrochemical microscopy, when electron donor – decamethylferrocene, was electrochemically recycled. Ejection of small fraction of decamethylferrocenium cation from oil to aqueous phase was also noticed.
期刊介绍：
Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
