Facile synthesis of Co3O4 with different morphologies loaded on amine modified graphene and their application in supercapacitors

A simple and scalable method has been developed for the growth of Co3O4 on amine modified graphene (NH2-Gs), synthesized from the hydrothermal reaction of graphene oxide in the presence of ammonia. Among the synthesized samples, Co3O4/NH2-G(2) exhibits the highest capacitive performance and a satisfactory cycling performance.228
