摘要：Cobalt-iron oxides have attracted much attention as electrode materials for supercapacitors. Graphene loaded with cobalt ferrite (CoFe2O4) nanoparticles can exhibit enhanced specific capacitance. Here, we present three-dimensional (3D) crumpled graphene (CGR) loaded with CoFe2O4 nanoparticles. The CoFe2O4-graphene composites were synthesized from a colloidal mixture of GO, FeCl3⋅6H2O, and CoCl2⋅6H2O by one step aerosol spray pyrolysis. The CoFe2O4-GR composites displayed a morphology resembling a crumpled paper ball, and the size of the CoFe2O4 and CGR in the composites was around 5 nm and 500 nm, respectively. The highest specific capacitance of the CoFe2O4-graphene composites was 253 F g–1.
