Abstract

Here we report low temperature growth of two dimensional freestanding nanoplatelets of manganese oxide (Mn3O4) through a simple and cost-effective wet chemical route without the utilization of capping agents. The pristine 2D Mn3O4 nanoplatelets have size and thickness between 100 and 200 nm and 3.5�5.1 nm respectively as corroborated by FESEM, TEM and AFM analysis. The electrochemical performance of the 2D Mn3O4 based electrode is studied using three electrode configuration and 1 M KOH as electrolyte where the remarkably high specific capacitance of 537 F/g (at 2 A g-1) is observed. Moreover, the 2D Mn3O4 based electrode is also found to exhibit an excellent retention of specific capacitance (� 93) up to 5000 cycles. Thus enriched electrochemical performance of 2D Mn3O4 nanoplatelets reveals its potential as electrode material in supercapacitor device applications. © 2024 Elsevier Ltd
