Obiettivo

A number of systems modelling metal catalysts on metal-oxide support will be studied theoretically. The objects under investigation are the monoatomic and highly dispersed platinum species attached to the Broensted acid sites of zeolites as well as nickel clusters on alumina support.

The main objective of the study is to identify the strong metal-support interaction in the theoretical results and to rationalize it through the features of the electronic structure of the systems under study. The cluster approach in the framework of the density functional theory will be used to carry out quantum-chemical calculations. To improve the reliability of the cluster models special provisions will be made to implement a pseudopotential technique which allows one to impose proper boundary conditions. Furthermore, the constrained space orbital variation scheme will be implemented within the density functional computer programs to yield a detailed analysis of the chemisorption interaction.
