Abstract
Metal-support interaction (MSI) in catalysis is discussed in terms of the surface electron gas model (SEGM), which accounts for the case of inhomogeneous surface. In the case of MSI the initial heat of adsorpti on as well as the effective charge of adsorbed particles can differ fr om that in the absence of metal-support interaction. Conditions at whi ch either negligible small adsorption coefficients (reaction rate) or their enhancement compared to non-MSI conditions are presented.
