Graphical Abstract

We have succeeded in synthesizing diamond from graphene oxide (GO) using a high temperature/high pressure method. This structural phase transition was characterized from Raman and XPS spectra. Due to its high chemical reactivity, GO can be doped with various heteroatoms. Therefore, we propose that heteroatom-doped diamond can be synthesized from GO.

Abstract

Herein we report a high temperature and high pressure driven crystallization of two-dimensional graphene oxide (GO) nanosheets to three-dimensional diamond. The successful phase transformation was confirmed using X-ray diffraction (XRD), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The phase transition platform will available to utilize for a wide variety of diamond doping employing, for example, nitrogen or other light elements, in which the correspondingly doped GO is used as the starting material.
