Synthesis of graphene by low-temperature exfoliation and reduction of graphite oxide under ambient atmosphere

Abstract
We firstly report a facile approach to produce few-layered graphene sheets by low-temperature (130 °C) exfoliation and reduction of graphite oxide under ambient atmosphere with the aid of HCl. The obtained graphene materials exhibited high BET specific surface area (500 m2 g−1) and excellent electrical conductivity (1200 S m−1).
