Australian researchers develop a new efficient method to reduce graphene oxide

Researchers from Australia's Anstro institute and Deakin University developed an efficient method to prepare porous and reduced graphene oxide. They say that this one-step, catalyst-free, high penetration and through-put technique offers for the first time a significant advantage over previously reported graphene oxide (GO) solution reduction mechanisms.

The new technique, which uses gamma irradiation, maintains the naturally densely packed morphology of GO bucky-papers without causing the dramatic exfoliation of the graphene layers caused by chemically reduced routes.
