NiFe2O4 quantum dots anchored on flower-like Ni-MOF with enhanced electrochemical performance for supercapacitors

NiFe 2 O 4 QDs@Ni-MOF-10 composite with a specific capacity of 852.3 mA h g −1 at 1 A g −1 was prepared by a two-step solvothermal method. The hybrid device assembled by the composite and AC delivered a high specific energy and can illuminate a LED.
