The role of metallic component (Pt, Pd) in Pt(Pd)/WO3/ZrO2 catalysts for isomerization of n-heptane
Доклады на конференциях
The charge state of platinum and palladium in tungstated zirconia catalysts is studied depending on the conditions of thermal activation. It was shown that in calcined catalysts there are platinum and palladium atoms in a charged and metallic state. It was found that the presence of charged Pt and Pd atoms in catalysts promotes an increase in the catalytic activity of the samples in the isomerization of n-heptane. Charged forms of platinum and palladium are formed during the calcination of Pt(Pd)/WO3/ZrO2 catalysts in the air flow.
