Efficient one-pot combustion synthesis of few-layered graphene

Abstract

We present the results of exploratory research on the fast synthesis of few-layered graphite via a self-propagating high-temperature synthesis (SHS). We reported previously that different solid carbonates and gaseous carbon oxides could be directly converted into novel nanocarbons using strong reducers and SHS approach. In the current work, such combustion synthesis (CS) is extended toward the direct and efficient reduction and exfoliation of graphite oxide (GO) or fluorinated graphite (CFx) using different reducers (Si, Mg, NaN3, Li3N) into few-layered graphene (FLG).
