"New Possibilities for Understanding Complex Metal Hydrides via Synchrotron X-ray Studies: Making Synchrotron X-ray Characterization Relevant to the Hydrogen Economy"
This research seeks to understand the role of catalysts in hydride structures. X-ray absorption spectroscopy is used to examine the chemical interaction of catalysts (TiCl3) with the host hydride powder (NaAlH4). Results show that TiCl3 transforms first to metallic Ti—then reacts with Al3+ in NaAlH4 to form TiAlx complexes. It remains unclear, however, whether the formation of those TiAlx complexes is directly related to catalysis of the H2 desorption reaction in the hydride. Our research uses several specialized synchrotron X-ray techniques to elucidate the interactions between transition metal salts additives and hydride host structures. This presentation will describe those techniques and their use in describing the physical and chemical processes occurring between the hydrides and catalysts. |
