Metal cluster alloys and oxides: Elucidating structural and electronic effects in governing the reactivity and catalytic role of matter in finite dimensions. Progress report, December 2, 1992--December 10, 1993

摘要

The discovery of a new class of molecular clusters (metallocarbohedrenes (Met-Cars)) was a potentially major finding in cluster science; a method has been developed for producing bulk quantities of this material. Attention was also devoted to unraveling mechanisms of formation and reactive chemistry of Met-Cars. Abstracts are presented for 14 publications submitted, accepted, and/or published during the past year. Among the materials studied were (TiN)(sub n)(sup +), Cu/Sb and Cu/Bi alloy clusters, Cu/C clusters, Cu/Se and Ag/Se clusters, Ti(sub 8)C(sub 12)(sup +), Mg(sup +)(H(sub 2)O)(sub n) clusters, Zr/C and Ta/C clusters, Ti(sub x)Zr(sub y)C(sub 12) and Ti(sub x)Hf(sub y)C(sub 12) (x+y=8), etc.
