Abstract

Abstract : We demonstrate a Si-mediated environmentally friendly reduction of graphene oxide (GO) and the fabrication of hybrid electrode materials with multiwall carbon nanotubes and nanofibers. The reduction of GO is facilitated by the nascent hydrogen generated by the reaction between Si and KOH. The overall process consumes 10 to 15 μm of Si each time and the same Si substrate can be used multiple times. Abstract : Here, we demonstrate a Si-mediated environmentally friendly reduction of graphene oxide (GO) and the fabrication of its hybrids with multiwall carbon nanotubes and nanofibers. The reduction of GO is facilitated by nascent hydrogen generated by the reaction between Si and KOH at ∼60 °C. The overall process takes 5 to 7 minutes and 10 to 15 μm of Si is consumed each time. We show that Si can be used multiple times and the rGO based hybrids can be used for electrode materials.
