    Abstract
    For the first time, we developed porous Pt-Ni alloying nanoparticles with predominant (111) facets under intense magnetic fields. Electrochemical analysis revealed that the Pt-Ni alloying nanoparticles obtained at 2 Tesla exhibited a superior catalytic activity and durability for oxygen reduction reaction. This work demonstrated that the imposition of intense magnetic field could be considered as a new approach for developing efficient alloying electrocatalysts with preferential facets.For the first time, we developed porous Pt-Ni alloying nanoparticles with predominant (111) facets under intense magnetic fields.
