Abstract
The present invention relates to a process for converting a gas comprising NH3 in the presence of a cold plasma, preferably a plasma generated by dielectric barrier discharge (DBD), and of a catalyst comprising a support comprising alumina, nickel, and at least one promoter comprising iron. The invention also relates to such a catalyst, and to the use thereof for producing high value-added molecules like hydrogen (H2).
