zn-mof electrode material for supercapacitor applications

A zn-based metal–organic framework (zn-mof) was synthesized by a novel electrodeposition method. the prepared zn-mof was characterized using powder x-ray diffraction, fourier transform infrared spectroscopy, scanning electron microscopy (sem) and energy dispersive x-ray spectroscopy techniques. the supercapacitive behavior of synthesized mof was examined using cyclic voltammetry (cv), galvanostatic charge/discharge, and electrochemical impedance spectroscopy (eis) measurements in 3 m koh. sem images confirmed that zn-mof is composed of layered cuboid structure properly attached on to nickel foam substrate. electrochemical behaviors of the zn-mof/ni foam were also evaluated through gcd tests, which showed high specific capacitance of 288 f g^–1 at the current density of 2 a g^–1. the outcomes showed great potential of fabricated zn-mof as a high performance electrode material for electrochemical supercapacitors.
