NiO nanoparticles that are highly active for the ethane activa- tion have been prepared. These nanoparticles have been dis- persed on the surface of two different Nb2O5 materials by using a novel dry nanodispersion method. This article de- scribes the characterization and catalytic behavior of both series of catalysts as well as the nature of the active sites re-

quired for the transformation of ethane into acetonitrile and/or ethylene. It is demonstrated how such active sites present in the catalysts are obtained through this novel dry mixing method. The catalysts obtained are promising catalytic materi- als for both, ethane ammoxidation and oxidative dehydration (ODH) reactions.
