SINGLE CRYSTAL MIXED METAL OXIDE NANOSHEET MATERIAL COMPOSITIONS, METHODS AND APPLICATIONS

摘要

A nanosheet comprises a single crystal mixed metal oxide M1_xM2_yO₂ material composition that may comprise a single crystal Na_xCoO₂ material composition. The nanosheet may be prepared using a sequential process sequence that includes chelated mixed metal ion sol-gel mixture formation, autocombustion, isostatic pressing, electro kinetic demixing and calcination. This particular process sequence provides single crystal nanosheets having in-plane mutually perpendicular lateral sheet dimensions greater than about 10 microns by about 200 microns, and a thickness from about 5 to about 100 nanometers.
