Platinum and rhodium substitution by molybdenum and tungsten carbides for catalysis synthesis activations and uses



Platinum and rhodium substitution by molybdenum and tungsten carbides for catalysis synthesis activations and uses



Comptes Rendus de l'Academie des Sciences Serie II Mecanique-Physique-Chimie Sciences de l'Univers Sciences de la Terre 310(6): 707-714



The new synthesis of molybdenum and tungsten carbides with high specific surface area, as an original activating process of their surfaces, led to find new catalysts for the reactions usually catalyzed by platinum and rhodium. These two precious metals have been substituted in hydrocarbons reforming reactions, in selective dehydrogenation of cyclohexane into benzene and even, in the reactions of depollution of car exhaust pipe gases.
