Abstract

We report the intercalation of highly ordered pyrolytic graphite (HOPG) with alkali atoms (Li and K) using liquid ammonia. While the liquid ammonia alkali intercalation route of carbonaceous compounds is well known, to our knowledge it is the first report with the aim to intercalate HOPG. We characterize the successful intercalation by the apparent color change of the samples and the occurrence of the electron spin resonance signal due to the electron charge transfer. It is suggested that this synthesis route may facilitate the chemical exfoliation of graphite which could lead to high quality and defect free graphene.
