Fabrication of a vanadium-doped Ni-MOF with a hydrangea-like morphology as an electrode for high-performance supercapacitors

Abstract

In this work, we successfully fabricated a vanadium-doped Ni-MOF (NiV-MOF) with a three-dimensional hydrangea-like morphology via a simple one-pot hydrothermal synthesis method. As an electrode material, the Ni_0.9V_0.1-MOF demonstrated superior performance, achieving a specific capacitance of 1182 F g⁻¹ at a current density of 1 A g⁻¹.
