Adsorption and Oxidation Investigations over Pt/Al2O3 Catalyst: A Microcalorimetric Study
Artikel i vetenskaplig tidskrift, 2016

The differential adsorption heats of oxygen and NO, as well as catalytic oxidation behavior during NO oxidation and NO2 dissociation reactions over supported Pt-catalysts, were investigated by microcalorimetric measurements. The average heat of adsorption (Delta H) of oxygen ranged from 310 kJ/mol at 200 degrees C to 289 kJ/mol at 400 degrees C. Over this temperature range formation of platinum oxides and coverage dependence caused variations in the apparent heat of adsorption. NO heat of adsorption from 50 to 150 degrees C was near constant with an average value of 202 kJ/mol over the temperature range.
