Vacancy defects were introduced by oxidizing nanocarbon materials with oxygen and m-chloroperoxybenzoic acid, followed by heat treatment. To control the size of the vacancy defect, the defect structure was analyzed in detail by transmission electron microscope, X-ray photoelectron spectroscopy, and density functional theory's calculation. As a result, oxidation by oxygen proceeds even below 250 degree C, and carbon monoxide and carbon dioxide and vacancy defects were formed via carbonyl and lactone groups. By epoxidization of fullerene, epoxy, carbonyl, and lactone groups were formed. The amount of epoxy and lactone groups were reduced, and carbonyl and carbone were remained. Vacancy defects were observed using transmission electron microscope, but the proof that the vacancy defects were created by heat treatment is necessary in the future.

通过用氧和间氯过苯甲酸氧化纳米碳材料，然后进行热处理，引入空位缺陷。为了控制空位缺陷的尺寸，通过透射电子显微镜、X射线光电子能谱和密度泛函理论计算对缺陷结构进行了详细分析。结果，即使低于250℃，氧气的氧化也会进行，并且经由羰基和内酯基团形成一氧化碳和二氧化碳以及空位缺陷。通过富勒烯的环氧化，形成环氧基、羰基和内酯基团。环氧基和内酯基团的量减少，保留羰基和碳。使用透射电子显微镜观察空位缺陷，但未来需要证明空位缺陷是由热处理产生的。
