Metal clusters and nanoparticles.
By the 1980s, this field had matured, but a renaissance occurred with the availability of more advanced and sophisticated physical methods used to characterise such compounds. This renaissance can also be traced back to the rediscovery of colloid chemistry as well as to the realisation that metal-rich cluster complexes can be considered as a bridge between classical small metal complexes of the...
متن کاملMetal clusters inside out.
Solid-state chemistry of cluster compounds with metals in the left part of the periodic table is described. As a function of the metal valence electron concentration (VEC), characteristic changes occur with stepwise changing features. Strongly metal-metal-bonded and ligand-encapsulated clusters exist for large values of VEC. At decreased values, endohedral atoms stabilize the clusters, and with...
متن کاملImage states in metal clusters
The existence of image states in small clusters is shown, using a quantum-mechanical many-body approach. We present image state energies and wave functions for spherical jellium clusters up to 186 atoms, calculated in the GW approximation, where G is the Green’s function, and W the dynamically screened Coulomb interaction, which by construction contains the dynamic long-range correlation effect...
متن کاملAb Initio Study of the chemical reactivity of metal clusters and metal oxide clusters
In this work the transition metal and metal oxide clusters has been investigated with the aim of gaining a better insight into the mechanisms which govern their reactivity. The theoretical study of the structural and energetic properties of the clusters has been carried out within the framework of the density functional theory by means of a new family of gradient-corrected hybrid density functi...
متن کاملMetal Clusters and Nanoparticles One Contribution of 13 to a Theme Issue 'metal Clusters and Nanoparticles'
There is still no sharp discrimination between the terms ‘cluster’ and ‘nanoparticle’ in the literature. Clusters are mostly considered as species, exactly defined in chemical composition and structure, whereas the expression ‘nanoparticle’ usually means particles of less precise characterization, often linked with a certain size distribution and so to some extent substitutes the historical exp...
