Defect-Engineered FeC@NiCoS Nanospike Derived from Metal-Organic Frameworks as an Advanced Electrode Material for Hybrid Supercapacitors.

The rational synthesis and tailoring of metal-organic frameworks (MOFs) with multifunctional micro/nanoarchitectures have emerged as a subject of significant academic interest owing to their promising potential for utilization in advanced energy storage devices. Herein, we explored a category of three-dimensional (3D) NiCoS nanospikes that have been integrated into a 1D FeC microarchitecture using a chemical surface transformation process. The resulting electrode materials, , FeC@NiCoS nanospikes, exhibit immense potential for utilization in high-performance hybrid supercapacitors.
