For titanium-silicalite-1 in aqueous H2O2, the driving force that governs the equilibrium between the uncolored end-on ?1-titanium-hydroperoxo complex and the yellow-colored side-on ?2-Ti-peroxo complex (see picture) is the amount of water present in the system, as proven by in situ X-ray absorption near edge structure spectroscopy performed at 77 K.

Abstract
For titanium-silicalite-1 in aqueous H2O2, the driving force that governs the equilibrium between the uncolored end-on ?1-titanium-hydroperoxo complex and the yellow-colored side-on ?2-Ti-peroxo complex (see picture) is the amount of water present in the system, as proven by in situ X-ray absorption near edge structure spectroscopy performed at 77 K.File in questo prodotto:
