Abstract: Modification of the oxide surface of aluminium oxide with oxalate complexes of aluminium was carried out, followed by thermal treatment for the purpose of varying the ratio between the functional groups on the surface (OH groups, Lewis acid centres). It was established that the modification of g-Al2O3 causes a 1.5-fold increase in the amount of adsorbed platinum (IV) complexes and the fraction of these complexes strongly bound with the surface of the support. The effect of g-Al2O3 surface modification on the catalytic properties of the system Pt/Al2O3 was demonstrated. It was shown that an increase in the fraction of platinum forms strongly bound with the support causes an increase in the content of methylcyclopentane in the products of n-hexane isomerization and an increase in the selectivity of the formation of propylene in propane transformations.
