Two-dimensional β-MoO@C nanosheets as high-performance negative materials for supercapacitors with excellent cycling stability.

MoO has gained a great deal of attention as a promising electrode material in energy storage devices. In particular, the low dimensional MoO nanosheets coated with carbon layers are desirable electrode materials in supercapacitors. However, the fabrication or construction of β-MoO with a special morphology is difficult.
