Stable graphene suspensions are prepared using a new, green, and intriguing synthetic route. Graphene can be directly prepared by the fast deoxygenation of exfoliated graphite oxide in strong alkaline solutions at low temperatures (50–90 °C), in the absence of reducing agents. This study opens an opportunity towards the production of processable graphene on an industrial scale.
