Abstract

The results of X-ray studies of samples of purified and thermally modified shungite carbon are presented. The quantitative characteristics of short-range order are determined, and 3D models of regions of short-range ordering are presented. It is found that the structure of these regions can be described by turbostratic models, which are sets of five distorted graphene sheets, disoriented relative to each other, with sizes of 26 × 27 Å. The cluster thickness is 15 Å. The average distance between the sheets is 3.5 Å. As a result of the heat treatment of shungite carbon samples, graphene sheets are exfoliated. The thickness of the clusters forming the structure of regions of short-range ordering decreases to 7 Å.

摘要

给出了纯化和热改性的钨矿碳样品的X射线研究结果。确定了短程有序的定量特征，并提出了短程有序区域的3D模型。发现这些区域的结构可以用涡轮层模型描述，涡轮层模型是五个扭曲的石墨烯片的集合，彼此相对错位，尺寸为26×27。簇的厚度为15。纸张之间的平均距离为3.5Å。作为对钨矿碳样品进行热处理的结果，石墨烯片被剥落。形成短程有序区域结构的簇的厚度减小到7。
