A sharp increase in the atomic catalytic activity (ACA) of supported platinum catalysts in the model
reaction of n-pentane complete oxidation is found on going from the preliminary calcination temperature of
500–600°ë to a temperature of 700°ë. ACA increases by an order of magnitude for the Pt/γ-Al2O3 system,
~3 times for Pt/ZrO2, and ~1.5 times for Pt/CeO2. The per-gram activities of all catalysts decrease because of
a decrease in the dispersion of supported platinum with an increase in the temperature of preliminary calcination.
