LAYERED ALKALI IRIDATE, LAYERED IRIDIC ACID, AND IRIDIUM OXIDE NANOSHEET

摘要

Provided is a layered alkali iridate and a layered iridic acid to be used for producing iridium oxide nanosheets, and an iridium oxide nanosheet. A layered alkali iridate with composition of MxIrOy.nH2O (where M is a monovalent metal, x is 0.1 to 0.5, y is 1.5 to 2.5, and n is 0.5 to 1.5), wherein MxIrOy.nH2O has a layered structure. The M is potassium, and the layered alkali iridate has diffraction peaks at 29 diffraction angles of 13.0° and 26.0°. A layered iridic acid with a composition of HxIrOy.nH2O (where x is 0.1 to 0.5, y is 1.5 to 2.5, and n is 0 to 1), wherein HxIrOy.nH2O has a layered structure. This layered iridic acid has diffraction peaks at 2θ diffraction angles of 12.3° and 24.6°. A single crystalline iridium oxide nanosheet having a thickness of 3 nm or less.
