- •
Ni-Ce/Al2O3 and Ni-Pt/Al2O3 catalysts are reduced by γ-rays or H2-treatment.
- •
Nanosized intermetallic compounds are formed in the radiation-reduced catalysts.
- •
Ce segregates as CeO2 in Ni-Ce/Al2O3(H2). None of bimetallic phases was detected.
- •
The radiolytic catalysts display high performances in the benzene hydrogenation.
