Effect of soft template variation on the synthesis, physical, and electrochemical properties of Mn ₃ O ₄ nanomaterial

Abstract

In this study, the effect of surfactant variation has been investigated on the synthesis, the physical, and electrochemical performance of Mn3O4 (M1–M4) nanomaterials. The synthesized nanomaterials were successfully characterized by powder X-ray diffraction analysis, scanning electron microscopy, and energy dispersive X-ray analysis. Synthesized nanomaterials exhibited a tetragonal hausmannite phase (Mn3O4) with an average size of 22 nm. The electrochemical performance of these nanomaterials was investigated through cyclic voltammetry. The maximum specific capacitance for M1 was found to be 3.578028 F/g at 5 mV/s scan rate. The relation between power and energy density determined through the Ragone plot was found maximum for synthesized nanomaterials. M1 was found to be an efficient electrode material as compared to others.
