摘要：

A study of Rh6(CO)16 supported on zeolite has shown that the carbonyl cluster may be decarbonylated by O2 or in vacuo at 373 K without substantial loss of its molecular structure. On alumina Rh6(CO)16 was easily fragmented, zero-valent rhodium being oxidized by O2 and water to form Rh(I) which upon carbonylation gave Rh(I)(CO)2 complexes. The infrared spectra of zeolite-supported Rh6(CO)16 were compared with those of CO adsorbed on zeolitesupported small rhodium metal particles. The results suggest that zeolite is a suitable carrier to stabilize very small rhodium clusters. © 1979 Academic Press, Inc. All rights reserved.
