Optimization of the Electrochemical Nature of Ni/Co MOF Assisted by Zn Metal Centres for Better Electrode Performance in Hybrid Devices

Owing to the exceptional porous coordination chemistry and expanded redox culture of mixed metal organic framework (MMOF) materials are now presenting a hot matter for their potential usage in battery-supercapacitor electrodes. Here, we synthesized Ni/Co-MOF and its based Zn x-(Ni/Co) y-MOF nanoparticles containing different transition metals ratio; x: y= 0.25: 0.75, 0.50: 0.50, and 0.75: 0.25 by hydrothermal process and named as ZMOF 1, ZMOF 2 and ZMOF 3. Their electrochemical profile was carried out by CV, GCD and EIS characterization in three electrode setup. Among the MOFs nanoparticles, partially Zn enriched ZMOF 1 shows prominent specific capacity of 177.23 and 181.12 C g− 1 in 1.0 and 3.0 M KOH electrolyte solution at current density of 0.3 A g− 1 along with good rate capability performance. Meanwhile, it retains brilliant specific capacity∼ 86% of its original value compared to other …
