Tin-Powder Mediated Facile Route for the Reduction of Graphene Oxide

Abstract:

A facile approach for the reduction of graphene oxide (GO) using of Tin (Sn) powder and dilute hydrochloric acid at room temperature (RT) and at 50 °C upto 0.5-3 h has been reported. The as-prepared high quality crystalline graphene has been characterized using various analytical techniques. The rate of reduction scales with the reaction time for both RT and 50 °C as evidenced from electrical conductivity data. The graphene samples reduced at RT shows high electrical conductivity value due to the presence of un-reacted Sn-particles. resulting the enhancement in the However, the graphene prepared at 50 °C shows low electrical conductivity in comparison to the room temperature reduced graphene. XPS elemental analysis is in good agreement with this observation.
