Abstract
Official abstract text for this publication.
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 M x IrO y .nH 2 O (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 M x IrO y .nH 2 O 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 H x IrO y .nH 2 O (where x is 0.1 to 0.5, y is 1.5 to 2.5, and n is 0 to 1), wherein H x IrO y .nH 2 O 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.

What is claimed is: 1 . An alkali iridate with composition of M x IrO y .nH 2 O (where M is an alkali metal, x is 0.1 to 0.5, y is 1.5 to 2.5, and n is 0.5 to 1.5), wherein M x IrO y .nH 2 O has a layered structure. 2 . The layered alkali iridate according to claim 1 , wherein the M is potassium and the layered alkali iridate has diffraction peaks at 2θ diffraction angles of 13.0° and 26.0°. 3 . An iridic acid with composition of H x IrO y .nH 2 O (where x is 0.1 to 0.5, y is 1.5 to 2.5, and n is 0 to 1), wherein H x IrO y .nH 2 O has a layered structure. 4 . The layered iridic acid according to claim 3 having diffraction peaks at 2θ diffraction angles of 12.3° and 24.6°. 5 . An iridium oxide nanosheet composed of single crystalline iridium oxide sheet with a nanosheet morphology having a thickness of 3 nm or less.
