from first principles PP-I-1

PP-III-75domain the ZrO 2 -15%Y 2 O 3 +1% Pd is more active, since it is known that the increase ofyttrium oxide in ZrO 2 leads to an increase in the mobility of oxygen, and thus to an increase inactivity.1 2Fig. 2.1- ZrO 2 -6,5%Y 2 O 3 +1% Pdcatalyst after use,2 - ZrO 2 -15%Y 2 O 3 +1% Pdcatalyst after use.According to electron microscopy (Fig. 2) in the ZrO 2 -6, 5% Y 2 O 3 +1% Pd catalyst afterworking as a metalcatalyst after working as a metal, significant amount of Palladium issituated on the inner surface of the sample, while in the ZrO 2 -15%Y 2 O 3 +1%Pd catalystamount of Palladium on the inner surface is insignificant.231
