Abstract

L'invention porte sur un procédé de préparation de nanostructures d'oxydes métallique consistant à mélanger une solution précurseur avec une solution basique pour former un mélange réactif, puis à chauffer le mélange réactif dans une enceinte close pour y produire une pression supérieure à la pression ambiante. L'invention porte également sur des nanostructures d'oxydes métallique présentant un allongement moyen d'au moins environ 4:1, et une largeur de section transversale d'environ 100 manomètres ou moins.
