Beschreibung
Zusammenfassung:	The present invention describes a preparation method for preparing a catalyst made up of a Fe and Co metal alloy in several ratios in the form of nanoparticles embedded in a graphitic carbon matrix. Another object of the invention is also the prepared catalyst which in a surprising manner selectively catalyses the hydrogenation of carbon dioxide into isobutane. La présente invention concerne un procédé de préparation pour préparer un catalyseur constitué d'un alliage de Fe et de Co dans plusieurs rapports sous la forme de nanoparticules incorporées dans une matrice de carbone graphitique. Un autre objet de l'invention est également le catalyseur préparé qui catalyse de manière surprenante l'hydrogénation du dioxyde de carbone en isobutane.
