Abstract

Selon un mode de réalisation, la présente invention concerne un procédé de fabrication d'un film catalytique. Ce procédé consiste à appliquer un courant électrique à une cellule électrochimique comportant une anode, une cathode et une solution renfermant un composé permettant la formation d'un film ainsi qu'une source d'ions nitrate; ceci permet de former le film catalytique. Selon un autre mode de réalisation, la présente invention se rapporte à un procédé de préparation d'un sel d'hydroxylammonium. Ce second procédé consiste à prendre une cellule électrochimique comportant une anode, une cathode et un séparateur positionné entre l'anode et la cathode en vue de délimiter un compartiment catholyte entre la cathode et le séparateur et un compartiment anolyte entre l'anode et le séparateur; à charger le compartiment catholyte d'une première solution contenant un médiateur et un composant renfermant de l'azote; à charger le compartiment anolyte d'une seconde solution renfermant un composé ionique; à faire passer un courant dans cette cellule électrochimique en vue de produire un sel d'hydroxylammonium dans le compartiment catholyte; et à récupérer ce sel d'hydroxylammonium dans le compartiment catholyte.
