Mechanochemical process on layered compounds MoO3 and graphite to construct heterostructure composites with efficient lithium storage performance

This work successfully prepared homogeneous heterostructure nanocomposites comprised of few-layered MoO3 and graphite nanosheets (MoO3/C) on a large scale via a ball-milling method with bulk MoO3 and expandable graphite as raw materials. The shear and impact forces generated by the agate balls with...

Zusammenfassung:This work successfully prepared homogeneous heterostructure nanocomposites comprised of few-layered MoO3 and graphite nanosheets (MoO3/C) on a large scale via a ball-milling method with bulk MoO3 and expandable graphite as raw materials. The shear and impact forces generated by the agate balls with a diameter of 2 mm can present the most ideal synergistic effect to strip the MoO3 nanosheets from its mother body with a small size and thickness. The obtained MoO3 nanosheets are distributed homogeneously on the surface of carbon nanosheets (
