Preparation and characterization of polyacrylonitrile-based activated carbon nanofibers/graphene (gacnfs) composite synthesized by electrospinning

In this work, activated carbon nanofibers (ACNFs) and graphene-derived rice husk (GRH)/ACNF composites (gACNFs) were straightforwardly fabricated through a simple electrospinning process and were consequently activated by using a physical method. The morphological, structural, and textural propertie...
