Abstract [en]

Much attention is now being focused on Quasicrystals in the light of the recent Nobel Prize in chemistry. Although these exotic materials have been known to us since 1982, little has been known concerning the detailed atomic structures of icosahedral quasicrystals until recently. Based on the constituent atomic clusters in icosahedral quasicrystals, they can be classified into one of three families: Bergman-, Mackay- and Tsai-type quasicrystals. The Bergman-type family, also referred to as the Frank-Kasper type family (FK-type) is by definition structurally related to other well-known FK-type alloys such as LaNi5 and MgZn2 which are already being used commercially in high-capacity electrodes and hydrogen fuel cells. In spite of this fact, few investigations have been made in order to explore the hydrogen storage properties of quasicrystals and their related approximants. In this work we will give an introduction to the crystal chemistry of quasicrystals and approximants, highlighting their structural relation to simple FK-type alloys and their potential use as hydrogen storage materials.
