Abstract

Three-dimensional (3D) porous NiCo₂S₄ nanonetworks were fabricated on nickel foam (NF) through an anion exchange reaction between NiCo₂O₄ nanosheets (hydrothermally grown on NF) and Na₂S, and showed a very high specific capacitance of 1501.2 F g⁻¹ at 1 A g⁻¹ (even 2.5 times higher than that of NiCo₂O₄ nanosheets) and robust cycling stability for supercapacitors.
