Nanosheet-assembled porous MnCoO microflowers as electrode material for hybrid supercapacitors and lithium-ion batteries.

Herein, the MnCoO microflowers (MFs) assembled by two-dimensional (2D) porous nanosheets were prepared through an initial solvothermal reaction with a subsequent annealing process. In this architecture, many interconnected 2D thin nanosheets were self-assembled together to form a 3D hierarchical MF with plenty of open channels. Such structure endows these MnCoO MFs with large specific surface area of 156.

Uniform MnCoO porous nanowires and quasi-cubes for hybrid supercapacitors with excellent electrochemical performances.

In this work, uniform MnCoO nanowires (NWs) on stainless steel foil (SSF) were prepared through a facile, cost-efficient, and eco-friendly hydrothermal method at 120 °C with a post-calcination process in air. The microstructure of MnCoO samples could be tuned at different hydrothermal temperatures and quasi-cubes (QCs) were obtained in high yield at 150 °C. The MnCoO NW powder peeled off from the SSF delivered an outstanding capacity of 248.

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

In this work, porous MgCoO nanoflakes (MgCoO NFs) and MgCoO nanocubes (MgCoO 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 MgCoO samples can be easily tuned by changing the hydrothermal temperature and reaction time, respectively. The porous MgCoO NFs with an average pore size of 12.
