Simple synthesis of rGO (reduced graphene oxide) by thermal reduction of GO (graphene oxide)

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The rGO has been synthesized successfully by combination of modified Hummers method and thermal reduction. First, the GO was synthesized by modified Hummers method (chemical exfoliation) of graphite flake. This reaction obtained graphite oxide (GrO) as intermediate material.
