Summary:The invention relates to a process for preparing a catalyst, a catalyst being provided in the form of a metal oxide catalyst comprising at least one element selected from the group consisting of Mo, Te, Nb, V, Cr, Dy, Ga, Sb, Ni, Co, Pt and Ce. According to the invention, it is provided that the catalyst K is subjected to an aftertreatment to increase the proportion of the M1 phase, the catalyst K being contacted with steam at a pressure below 100 bar and/or being contacted with oxygen to obtain an aftertreated catalyst K'. The invention further relates to a catalyst K' prepared by the process and to a process for oxidative dehydrogenation with a catalyst K' according to the invention. L'invention concerne un procédé de fabrication d'un catalyseur, obtenu sous la forme d'un catalyseur à base d'oxyde métallique, qui contient au moins un élément du groupe comprenant les éléments Mo, Te, Nb, V, Cr, Dy, Ga, Sb, Ni, Co, Pt et Ce. Selon l'invention, le catalyseur K est soumis à un retraitement destiné à accroître la teneur en phase M1. Pour produire le catalyseur retraité K', le catalyseur K est mis en contact avec de la vapeur d'eau à une pression inférieure à 100 bar et/ou avec de l'oxygène. L'invention concerne en outre un catalyseur K' fabriqué par ce procédé, ainsi qu'un procédé de déshydrogénation oxydative utilisant un catalyseur K' selon l'invention.
