The local structure and oxidation state of titanium (Ti) clusters, acting as catalysts for hydrogen (H) absorption and desorption in Mg nanoparticles (NPs) will be studied by Ti K-edge XAFS. Measurements at low temperature under vacuum will be carried out on different samples, selected to represent the different steps of the hydrogen sorption cycle: as-prepared, after hydrogen absorption, and after hydrogen desorption. Samples with different Ti content will be investigated. This experiment aims to contribute fundamental understanding in the field of nano-catalysts for H-storage materials.
