Beschreibung
Zusammenfassung:	The invention relates to a method for preparing a catalyst, wherein a catalyst precursor is coated with an ALD-coating such that Al2O3-layer is arranged on the surface of the catalyst precursor to form the catalyst, the formed catalyst is treated by a thermal treatment in which temperature is increased in presence of nitrogen, and the catalyst is cooled after the thermal treatment in presence of nitrogen stream. Further, the invention relates to the catalyst and the use of the catalyst. L'invention concerne un procédé de préparation d'un catalyseur, un précurseur de catalyseur étant revêtu d'un revêtement ALD de sorte que la couche d'Al2O3 est disposée sur la surface du précurseur de catalyseur pour former le catalyseur, le catalyseur formé est traité par un traitement thermique dans lequel la température est augmentée en présence de l'azote, et le catalyseur est refroidi après le traitement thermique en présence d'un courant d'azote. L'invention concerne en outre le catalyseur et l'utilisation du catalyseur.
