Abstract
The structure and stability of (CoO)(x) clusters in siliceous ZSM5 (si licalite) and on SiO2 have been investigated using atomistic simulatio n techniques. The deconvolution of the energy into distortion and inte raction contributions revealed that the improved stability of the supp orted clusters is due to the energy gained from the cluster-host inter action. (CoO)(x) clusters in ZSM5 of between 4 and 6 Co atoms showed a n enhanced stability, while clusters larger than 18 Co atoms were ster ically limited inside the zeolite lattice.
