Abstract

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/TiO₂/Fe₃O₄ hybrid nanostructures. The synthesized nanostructures had metal nanoparticles with sizes of less than 2.8 nm. The synthesized nanostructures exhibited high H₂O₂ selectivity toward the H₂O₂ generation and also showed potential as a magnetic separable catalyst for both H₂O₂ synthesis and photocatalytic reaction.
