Recent progress in the synthesis of graphene/CNT composites and the energy-related applications

Graphene and carbon nanotube (CNT) are representative carbon nanomaterials which have aroused numerous research interest due to their extraordinary material properties and promising application potentials, especially in the energy storage and conversion areas. However, the agglomeration happening in these materials has largely blocked their applications. Hybridization of CNT with graphene can, on one hand, prevent the agglomeration behavior, on the other hand, generate a synergistic effect between them with enhanced physical and chemical properties. There have been many studies conducted to find out the suitable approaches to synthesize graphene/CNT composites, and realize the application potentials of these structures. Based on the recent advances, this paper reviews the current research progress that has been achieved in synthesizing graphene/CNT composites, and the energy-related applications. Through this review, we aim at stimulating more significant research on this subject. (C) 2019 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science & Technology.
