Superparamagnetic Core/Catalytic Shell Heterostructures
In article number 2205665, Cailei Yuan and co‐workers design and successfully prepare electrochemical‐reconstructed NiFe/NiFeOOH core/shell nanoparticles confined in highly conductive amorphous carbon matrix. Benefiting from the unique superparamagnetic NiFe/catalytic NiFeOOH core/shell heterostructure, their oxygen evolution reaction performance is improved significantly with an alternating magnetic field stimulation as the consequence of magnetic heating effect.
