Preparation of fluffy graphene nanosheets from coal-tar pitch with nano-Al2O3 as filler

摘要

A simple method for high-yield production of fluffy few-layer graphene nanosheets (GNs) was developed. Results show that the GNs with crystalline structure can be prepared by direct carbonization of coal-tar pitch with nano-Al2O3 as filler. (C) 2015 Elsevier B.V. All rights reserved.
