CHEMICAL METHOD CATALYSED BY FERROMAGNETIC NANOPARTICLES

A method for the heterogeneous catalysis of a chemical reaction using, in a reactor, at least one reagent and a catalytic composition that can catalyze the reaction within a given range of temperatures T. At least one reagent is brought into contact with the catalytic composition which includes a fe...

Beschreibung
Zusammenfassung:	A method for the heterogeneous catalysis of a chemical reaction using, in a reactor, at least one reagent and a catalytic composition that can catalyze the reaction within a given range of temperatures T. At least one reagent is brought into contact with the catalytic composition which includes a ferromagnetic nanoparticulate component whose surface is formed at least partially by a compound that is a catalyst for the reaction; the nanoparticulate component is heated by magnetic induction in order to reach a temperature within the range of temperatures T; and the reaction product(s) formed on the surface of the nanoparticulate component are recovered. A catalytic composition includes a ferromagnetic nanoparticulate component that can be heated by magnetic induction to the reaction temperature, whose surface thereof is at least partially formed by a catalyst compound for the reaction. The catalyst is heated by the effect of the magnetic field.
