The present invention relates to a method of manufacturing a catalyst for the treatment of exhaust gases. Le procédé comporte les étapes suivantes: 1 ) mélange d'une charge, d'un liant et d'au moins une partie de la phase active, 2) mise en forme du mélange, 3) séchage et éventuellement calcination, 4) introduction de la partie de la phase active restante, 5) séchage puis activation. The process includes the following steps: 1) mixing a filler, a binder and at least part of the active phase, 2) shaping of the mixture, 3) drying and possibly calcination, 4) introduction of the part of the remaining active phase, 5) drying then activation. Il est caractérisé en ce que la majeure partie des métaux de la mine du platine ou des métaux additionnels sont introduits dans le liant lors de la première étape. It is characterized in that the majority of the metals of the platinum mine or of additional metals are introduced into the binder during the first step.
