摘要: 1H, 23Na and 29Si solid-state NMR spectroscopy was used to investigate the formation of fiberglass zirconium-silicate supports catalysts (glass → leached catalyst). The main emphasis made on OH-H2O domains in their role catalyst preparation. size accessibility H-D exchange were determined. Platinum shown be anchored bridging hydroxyl groups. quantum-chemical calculations demonstrated activity Pt0 clusters forming depend nuclearity.
