IR study of active sites for n-heptane isomerization over MoO3-ZrO2

The property of acidic sites onMoO3-ZrO2 was studied for n-heptane isomerization.A2,6-lutidine IRstudy showed that the introduction of MoO3 on ZrO2 partially eliminated the absorbance band at 1605 cm−1 ascribed to Lewis acid sites corresponding to the presence of the monoclinic phase of ZrO2 and de...
