Abstract: Recently, spinel structures (AB2O4) Nanoparticles (NPs) having binary and ternary mixtures
of metal oxides have been established as promising redox catalysts. Due to the presence of two mixed
valence metal cations, transport of electrons takes place easily between multiple transition-metal cations
with relatively low energy of activation. Among these, spinel cobaltite (MCo2O4) is very attractive
due to its low cost, non-toxicity, higher stability, higher electronic conductivity and electrochemical
property. To date, MCo2O4 has been used in the fabrication of supercapacitors, electrodes for oxygen
evolution reaction, and electrochemical sensors for glucose. A variety of MCo2O4materials have been
synthesized, characterized, and utilized in the fabrication of super capacitors, electrodes for oxygen
evolution reaction, and electrochemical sensors for glucose. The progress in the field of the spinel
MCo2O4 materials opens the door to novel and efficient applications in the nanoscience and nanotechnology,
and elctrochemistry.
