Abstract

L'invention concerne un procédé de préparation d'une structure de catalyseur comprenant un catalyseur métallique et un oxyde métallique, le procédé comprenant les étapes suivantes : utiliser une solution d'un précurseur d'oxyde métallique; utiliser un solvant réactif aqueux dans un état supercritique ou subcritique; mélanger la solution de précurseur d'oxyde métallique avec le solvant réactif aqueux supercritique ou subcritique pour former un mélange réactif aqueux; injecter le mélange réactif aqueux dans un tube de réaction par une première entrée; rétablir des conditions supercritiques ou subcritiques dans le tube de réaction si nécessaire; permettre la réaction hydrothermique du précurseur d'oxyde métallique dans le mélange réactif aqueux supercritique ou subcritique dans le tube de réaction pour former des nanoparticules d'oxyde métallique; utiliser, à l'ambiante, une solution d'un précurseur métallique dans un solvant; injecter la solution du précurseur métallique dans le tube de réaction par une deuxième entrée en aval de la première entrée; rétablir des conditions supercritiques ou subcritiques dans le tube de réaction si nécessaire; permettre la réaction de réduction du précurseur métallique dans le mélange réactif supercritique ou subcritique pour former des nanoparticules métalliques sur les nanoparticules d'oxyde métallique; extraire la structure de catalyseur du tube de réaction par une sortie. La structure catalytique peut être un catalyseur d'échappement et servir dans la catalyse d'oxydation diesel ou la catalyse à trois voies.
