Summary: Defect engineering is a feasible approach to enhance the properties of nanomaterials, but introducing dual defects in a simple way remains a challenge. In this study, Fe-doped NiCo-S nanosheets with improved charge storage kinetics were successfully synthesized. These materials showed high specific capacitance and excellent rate performance, making them promising electrode materials for supercapacitors and the OER. The introduction of dual defects through a two-step solvothermal method provides a rational strategy for preparing high-performance electrode materials.
