TWO-DIMENSIONAL PARTICLE, METHOD FOR PRODUCING TWO-DIMENSIONAL PARTICLE, AND MATERIAL

WIPO Patent Application WO/2023/162423

A1

A purpose of the present disclosure is to provide a two-dimensional particle which can provide a material having moisture resistance. Another purpose of the present disclosure is to provide: a method for producing the two-dimensional particle; and a material containing the two-dimensional particle. The two-dimensional particle according to the present disclosure has at least one layer and contains a Li atom and an I atom, in which the layer includes a layer main body represented by the formula: MmXn (wherein M represents at least one metal selected from metals belonging to Group 3, Group 4, Group 5, Group 6 and Group 7; X represents a carbon atom, a nitrogen atom or a combination thereof; n represents 1 to 4 inclusive; and m is larger than n and is 5 or less) and a modified or terminal end T present on the surface of the layer main body (wherein T represents at least one residue selected from the group consisting of a hydroxyl group, a fluorine atom, a chlorine atom, an oxygen atom and a hydrogen atom), the Li atom comprises a first component and a second component having a larger chemical shift than that of the first component in which the chemical shift is measured by 7Li NMR, and the ratio of the amount of the first component to the total amount of the first component and the second component is 55 at.% or more.
