Summary: The nanoarchitecture of transition metal oxides is considered crucial in supercapacitor electrode materials. In this study, Co3O4 doped with transition metals (Ni, Mn, and Zn) was synthesized using a simple co-precipitation technique. X-ray diffraction analysis showed a face-centered cubic lattice for Co3O4, with slight variations in lattice parameters when iso-valent metals were doped at the Co site. The incorporation of a nominal amount of Ni, Mn, and Zn resulted in a favorable porous morphology and increased porosity. Electrochemical measurements revealed that Mn0.05Co2.95O4 displayed the highest specific capacitance of 80.8 F/g, making it a potential candidate for electrochemical supercapacitor applications.
