Novel synthesis of ZIF67-derived MnCo2O4 nanotubes using electrospinning and hydrothermal techniques for supercapacitor

Cation substitution effects (Mn, Ni, and Zn) on ZIF-67 derived spinel modified with 3DGO for the detection of NO2 gas with high sensitivity and selectivity

“…Another group, Yang and co-worker performed a manganese substitution in ZIF-67 for synthesizing the MnCo 2 O 4 nanotube spinel, which remarkably enhanced the performance of this supercapacitor with a Coulombic efficiency of 91.2%. 23 From the theoretical perspective, M 2+ and Co 3+ cations (MCo 2 O 4 , M = Mn, Ni, and Zn) always occupy part or all of the octahedral and tetrahedral centers to generate a normal/inverse spinel structure, which can exhibit various structural/composition-dependent advantages. Apart from that, this type of spinel structure also exhibits good selectivity due to the interaction of the gas molecules with the structural metal or organic linker.…”
