MOF-derived NiAl₂O₄/NiCo₂O₄ porous materials as supercapacitors with high electrochemical performance

Abstract

We prepared NiAl 2 O 4 /NiCo 2 O 4 electrode materials with a high specific capacitance of 2870.83 F g −1 at 1 A g −1 using metal–organic frameworks (MOFs) as precursors. The NiAl 2 O 4 /NiCo 2 O 4 //AC device showed a retention of 72.9% after 2000 cycles.
