Facile hydrothermal synthesis of porous MgCo₂O₄ nanoflakes as an electrode material for high-performance asymmetric supercapacitors.

ABSTRACT: In this work, porous MgCo₂O₄ nanoflakes (MgCo₂O₄ NFs) and MgCo₂O₄ nanocubes (MgCo₂O₄ NCs) have been successfully synthesized through a simple hydrothermal method combined with a post calcination process of the precursor in air. The morphology of the MgCo₂O₄ samples can be easily tuned by changing the hydrothermal temperature and reaction time, respectively. The porous MgCo₂O₄ NFs with an average pore size of 12.5 nm had a BET specific surface area up to 64.9 m² g^-1, which was larger than that of MgCo₂O₄ NCs (19.8 m² g^-1). The MgCo₂O₄ NFs delivered a specific capacitance of
