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.
