Abstract: One is enough! The changes of the electronic structure induced by the adsorption of water and ammonia in the catalyst titanium silicalite-1 (TS-1) are investigated by means of (resonant) valence-to-core X-ray emission spectroscopy. Based on spectra simulations using density functional theory it is concluded, contrary to the widely accepted view, that the Ti-sites of TS-1 can coordinate only one molecule of ammonia and water.
