Liquid phase exfoliation of MoO₂ nanosheets for lithium ion battery applications.

ABSTRACT: Molybdenum dioxide (MoO₂) is a layered material which shows promise for a number of applications in the electrochemical energy storage arena. Mostly studied as a bulk layered material, MoO₂ has not previously been exfoliated in large quantities. Here we demonstrate the liquid phase exfoliation of MoO₂ in the solvent isopropanol, yielding reasonable amounts of good quality nanosheets. However, we found that, when dispersed in isopropanol under ambient conditions, MoO₂ nanosheets are gradually oxidized to higher oxides such as MoO₃ over a period of days. Conversely, if the nanosheets are processed into dried films immediately after exfoliation, and before oxidation has had a chance to progress, the nanosheets are relatively stable under
