ABSTRACT:
An electrochemical process, in which a gaseous matter is reduced at the cathode and in which microemulsions of the water-in-oil (w/o) type are utilized as catholytes, the microemulsions having ionic electric transfer and matter interphase transfer capacities, and in which the oil phase consists of a perfluoropolyether having perfluoroalkyl end groups or functional end groups of the hydrophilic type, or of perfluorocarbons, the microemulsions being obtained by the use of perfluorinated surfactants, in particular those having a perfluoroalkylpolyether structure and/or by the use of an alcohol as a co-surfactant.
