Abstract

When alkali metals are loaded into zeolite, their clusters are stabilized in the cage. The average loading density of guest alkali metal can be widely controlled without structural change of zeolite framework. When potassium metal is loaded into zeolite LTA, K clusters with the effective size of 11 Å are generated in α cage. They are arrayed in a simple cubic structure. They show an itinerant electron ferromagnetism at low temperature depending on the guest potassium density. On the other hand, the diamagnetic Na clusters are generated in the cage of LTA. At a dilute Na loading density, clusters are generated in β cage of LTA. The paramagnetic Na cluster with the C3v symmetry is generated by the photoexcitation of diamagnetic cluster.
