Possibilities of Using Shungite as a “Container” for Carbon Nanoparticles

A model of the structure of thermally modified shungite carbon is proposed, which can be used as a container for the production and long-term retention of nanosized particles. Such nanoparticles are characterized by their inherent photoluminescence activity. Since nanosized carbon particles do not enter into chemical interaction with the shungite matrix under normal conditions, their luminescent properties are maintained for a long time. The description of the multilevel structure of shungite carbon by the model of randomly oriented agglomerations of turbostratic stacks of graphene sheets is confirmed by X-ray studies.
