Abstract
Surface acidity of aluminium oxide containing 5 wt.% lanthanum oxide h as been determined by IR spectroscopy. Strength of Lewis sites of the La2O3/Al2O3 system was lower than that of pure aluminium oxide, Howeve r, the presence of La2O3 in aluminium oxide increased the thermostabil ity of these sites in the mixed system.
