Abstract

The system formed of platinum deposited on the (100) surface of a Na0.7WO3 single crystal was studied by low energy He+ ion scattering and other surface sensitive techniques. After Pt deposition, flashing at or over approximately 500 K leads to the blocking of the Pt adsorptive sites by sodium oxide and to the consequent suppression of the capability to chemisorb CO at room temperature.
