摘要：

The restoration of graphitic structures from defective graphene oxide was examined in a reactive ethanol environment at ultrahigh temperatures. Structural analysis by Raman spectroscopy indicates that turbostratic structures as well as high crystallinity in multilayer graphene were accomplished by an ultrahigh-temperature process in an ethanol environment. This phenomenon is quite anomalous since it is in striking contrast to the results observed in inert environments, where graphitization proceeds significantly to form a Bernal stacking multilayer graphene. The suppression of graphitization in ethanol environments is probably caused by the simultaneous supply of carbon and etching species during the restoration process.
