Resumen:
This paper describes the preparation of a ZSM-5 zeolite layeronto conventional Si wafers and Si micromonoliths, by usingmicrowave-assisted seeded hydrothermal synthesis. A homogeneousZSM-5 zeolite layer up to 680 nm was obtained overthe external surface of a Si micromonolith (surface to volumeratio > 300,000 m -1 ) after only 4 min of hydrothermal synthesisat 453 K. As a proof of concept, the catalytic activity of theprepared ZSM-5 coated micromonoliths, after a conventionalPt ion-exchange process, was demonstrated in the combustionof traces of n-hexane (200 ppmV) in air.This paper describes the preparation of a ZSM-5 zeolite layeronto conventional Si wafers and Si micromonoliths, by usingmicrowave-assisted seeded hydrothermal synthesis.
