Abstract

The nonstoichiometric metal oxide Ni_0.3Co_2.7O₄ served as a support for small-sized Pt nanoparticles. The whole synthesis of the hybrid material can be kinetically controlled and no further surface-modification treatment was required. More importantly, the as-obtained strongly coupled Pt-Ni_0.3Co_2.7O₄ hybrid nanoflowers exhibit remarkably enhanced catalytic activities compared with Pt-NiO and Pt-Co₃O₄ hybrid samples. This result indicates that it is possible to optimize the catalytic performance of noble metals by using a nonstoichiometric metal oxides as a support instead of a stoichiometric metal oxide.
