Kinetic Study of the Reduction of Ni2+ Ions in an X Type Zeolite
There is a theoretical and practical interest in studying small metal particle formation. The electronic structure, the nature of metal-metal bonding and the crystallographic arrangement of the small particles can be modified as compared to these properties observed in bulk solids. In this field, a limited number of metallic elements have been investigated (1) (2) (3). Zeolites, which allow the introduction of transition cations in to well defined crystallographic sites constitute very good supports to obtain highly divided metallic particles. Recent work suggests that in certain cases the dispersion of these particles involve particular catalytic properties (3).
