- •
The surface content of the catalysts depends on the composition and thermal treatment.
- •
Migration of elements and its direction depend on the component type and pretreatment conditions.
- •
TOF in methanol oxidation is three times higher on Au/CeZrOx than on Au/CeO2 activated at 423 K.
- •
From all catalysts studied Au/CeZrOx is the best for low temperature total combustion of methanol.
