The development of a new concept of support for catalytic activity is important in the
development of catalysts. Dual-supports, composed of a mixture of two metal oxides, can
increase catalytic activities by controlling the oxidation state of metal catalysts, as well as
give multi-functionality to the catalyst, including photocatalytic properties and reusability. We
report an aqueous-phase synthesis of Pd/and Pt/TiO 2/Fe 3 O 4 hybrid nanostructures. The
synthesized nanostructures had metal nanoparticles with sizes of less than 2.8 nm. The …
