Abstract
Provided is a highly crystalline heteroelement-containing graphene including carbon (C) and, as a heteroelement (X), at least one element selected from the group consisting of nitrogen (N), phosphorus (P), arsenic (As), sulfur (S), boron (B), and silicon (Si). Also, spots belonging to either the orthorhombic system or the hexagonal system and having the symmetry of a single crystal are observed in the selected area electron diffraction.

A heteroelement-containing graphene comprising carbon (C) and, as a heteroelement (X), at least one element selected from the group consisting of nitrogen (N), phosphorus (P), arsenic (As), sulfur (S), boron (B), and silicon (Si), wherein spots belonging to either an orthorhombic system or a hexagonal system and having a symmetry of a single crystal are observed in selected area electron diffraction.
A method for producing a heteroelement-containing graphene comprising carbon (C) and, as a heteroelement (X), at least one element selected from the group consisting of nitrogen (N), phosphorus (P), arsenic (As), sulfur (S), boron (B), and silicon (Si), wherein spots belonging to either an orthorhombic system or a hexagonal system and having a symmetry of a single crystal are observed in selected area electron diffraction, the method comprising:
- dissolving a hetero 5-membered ring compound having, at least partially, a 5-membered ring structure in a polar aprotic solvent to prepare a raw material-containing liquid, wherein the 5-membered ring is formed by carbon (C) and the heteroelement (X), which is at least one selected from the group consisting of nitrogen (N), phosphorus (P), arsenic (As), sulfur (S), boron (B), and silicon (Si);
- and
- generating plasma in the raw material-containing liquid to polymerize the hetero 5-membered ring compound, thereby obtaining the heteroelement-containing graphene.
