Oxidation of CO on a Pt/Al2O3 Catalyst: From the Surface Elementary Steps to Lighting-Off Tests: III. Experimental and Kinetic Model for Lights-Off Tests in Excess CO

The adsorption of CO (1% CO/He mixture) at 300 K on a 2.9% Pt/Al2O3 catalyst leads to the detection of a strong IR band at 2075 cm−1 associated with weak and broad IR bands in the range 1900–1700 cm−1 ascribed to linear (denoted L) and multibound (bridged and threefold coordinated) CO species, respe...

Description
Summary:The adsorption of CO (1% CO/He mixture) at 300 K on a 2.9% Pt/Al2O3 catalyst leads to the detection of a strong IR band at 2075 cm−1 associated with weak and broad IR bands in the range 1900–1700 cm−1 ascribed to linear (denoted L) and multibound (bridged and threefold coordinated) CO species, respectively. In parts I and II of the present study it was shown that the L CO species is oxidized at T
