Abstract (en)
[origin: EP3834930A1] The present invention provides a method for preparation of MFI zeolites with encapsulated metal nanoparticles, wherein the metal is selected from Pt, Pd, Au and mixtures thereof, said method comprising the following steps:a) contacting at least one metal salt or complex, wherein the metal is selected from Pt, Pd, Au and mixtures thereof, with an alkoxysilane functionalized ionic liquid, in aqueous solvent, to form a first mixture;b) contacting a source of silica, alkali metal hydroxide, a structure-directing agent and optionally a source of alumina,, in aqueous solvent, to form a second mixture;c) combining the first mixture and the second mixture to form a third mixture;d) subjecting the third mixture to drying;e) subjecting the dried third mixture to hydrothermal crystallization to form the MFI zeolites with encapsulated metal nanoparticles.The method allows to prepare the metal-loaded MFI zeolites with reproducible metal loading, structural characteristics, in a simple, effective and reliable way.
