The models of adsorbo-catalitic centers for transition metals, which use the peculiarities of the electron-orbital structures as insulated and bounded atoms, have been analized. The important role of the unfilled d-orbitals, their orientation, changing of the occupation of d-shalls, and influence of the ligands with completely occupied d-orbitals were considered in connection with the catalytic activity of the transient metals. The new approach for enhanced catalytic properties, based on the film alloys of catalytic metals, was proposed.

Key words: adsorbtion, catalys, transition metals and alloys
