Patent ID: 8288302

Claim:
A method for preparing a substrateâ€”molecular sieve layer complex, comprising the application of 15 KHz-100 MHz of ultrasound in an induction stage which comprises of: (1) a first stage that: (a) combines a substrate and a coupling compound to prepare an intermediate 1; or (b) combines a molecular sieve particle and a coupling compound to prepare an intermediate 2; and (2) a second stage that: (a) combines a terminus of the coupling compound in intermediate 1 and a molecular sieve particle to form a substrateâ€”molecular sieve layer complex; or (b) combines a terminus of the coupling compound in intermediate 2 and a substrate to form a substrateâ€”molecular sieve layer complex; wherein the substrate is a silicon wafer; the molecular sieve particle is silicalite-1; and the coupling compound is 3-chloropropyltrimethoxysilane.
