摘要: Alumina supported Pd-Pt bimetallic catalysts prepared by electrochemical metal adsorption via ionization of adsorbed hydrogen. The palladium content the can be controlled thermal treatment processes parent catalysts, as well applying subsequent steps. were tested in n-hexane dehydrocyclization. Their catalytic properties depend strongly on applied before reaction. Omission oxygen results lower activities and selectivities for benzene formation.
