Zusammenfassung:A method for producing a multiphase mixed-oxide catalyst including at least one active phase based on bismuth molybdate and one co-catalyst based on iron molybdate and at least one amongst the two elements cobalt and nickel, includes the following steps:preparing a mixture of the precursors of said-mixed oxides in a solvent,making said precursors react through a microwave-assisted hydrothermal reaction, andisolating the mixed oxides to obtain the catalyst.A catalyst and a catalytic system prepared in this manner are related to the method as well as the uses of this catalyst and of this catalytic system, in particular in the oxidation of propene into acrolein.
