Title: Structure of Ti in TiCl3 Doped NaAlH4

Abstract

To elucidate the structure of Ti in Ti-doped sodium alanate used for hydrogen storage, XAFS studies were performed. In freshly prepared samples the majority of the Ti is present in interstitial positions in the NaAlH4. By increasing the desorption temperature, thus increasing the extent of hydrogen desorption, Ti migrates into the Al, finally forming a less active TiAl3 alloy.
