Graphene nanosheets derived from plastic waste for the application of DSSCs and supercapacitors

Abstract The present study reports the upcycling process of waste plastics into value-added product graphene nanosheets (GNs) and their subsequent applications in dye sensitized solar cells (DSSCs) and supercapacitors. Bentonite nanoclay has been used as an agent for the degradation of waste plastic...
