Abstract: Mass production of solution-based graphene derived from the precursor graphene oxide is a challenging step toward achieving industrialization of graphene. Inspired by a classical reducing method performed in the textile and paper making industries, we report here a rapid, cost-effective, and safer approach to the facile production of graphene that employs thiourea dioxide (TDO) as the green reductant. Graphene oxide was converted into high quality graphene within 30 minutes with TDO as the reductant under moderate reaction conditions. The C/O ratio of the TDO reduced graphene was ~5.9 with the yield of graphene from graphene oxide > 99%. This is better than the reduction efficiency under the identical experimental conditions by using L-ascorbic acid as the reductant which required a reaction time of about 48 hours. This simple and effective procedure should offer an alternative route to the mass production of solution-based graphene for practical applications.
