A porous MOF-derived NiMn2O4 material and its superior energy storage performance for high-performance supercapacitors

A binder-free C@NiMn 2 O 4 electroactive material was prepared through the calcination of a pristine Ni,Mn-MOF at 600 °C for 4 h. The fabricated C@NiMn 2 O 4 /NF electrode exhibits an area specific capacitance of 5.39 F cm −2 at 2 mA cm −2 .
