文摘
- •
Brønsted and Lewis acidic sites of zeolites promote ring-opening of cyclosiloxanes.
- •
The formed α-ω-silanediols are narrow enough to fit into zeolites framework.
- •
Fe-BEA zeolite can be regenerated by wet oxidation procedures with H2O2 and O3.
- •
Accumulation of unreacted and/or D4 by-products hampers zeolite performance.
