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

Detailed cation substitution studies of MCo 2 O 4 (M = Mn, Ni, Zn) spinel structures supported on 3D graphene oxide via solvothermal method have been carried out and used as a highly sensitive and selective NO 2 gas sensor at room temperature.
