Au cours des vingt dernières années, les universités, les entreprises et les centres de recherche des pays développés se sont engagés à trouver des carburants alternatifs qui éliminent, ou du moins réduisent, l'impact environnemental des combustibles fossiles. Parmi ces alternatives, le diméthyléther (DME) a récemment attiré l'attention et suscité un vif intérêt. Cet ouvrage présente une analyse systématique et détaillée de l'applicabilité des quasi-cristaux Al-Cu-Fe dans les réactions d'oxydation du méthanol, à partir desquelles on obtient le diméthyléther. Le combustible hydrogène est l'une des alternatives pour la durabilité environnementale. L'une des perspectives et innovations technologiques consiste à atteindre un marché important que représente l'industrie pétrolière et ses dérivés, ou plutôt l'industrie pétrochimique. Dans cette étude, l'alliage quasi-cristallin Al-Cu-Fe, préparé par coulée et traité thermiquement, a été soumis à des essais d'activité catalytique. Les résultats expérimentaux ainsi obtenus suggèrent que le catalyseur quasi-cristallin peut être considéré comme une excellente alternative pour les réactions catalytiques. Le faible coût de formation de l'alliage est un avantage supplémentaire de l'utilisation des quasi-cristaux comme catalyseurs industriels.
