Sonoelectrochemical Nanoarchitectonics of Crystalline Mesoporous Magnetite @ Manganese Oxide Nanocomposite as an Alternate Anode Material for Energy-Storage Applications

In this report, the synergetic sonoelectrochemical method was utilized to produce magnetite nanoparticles doped with MnO2 assistance of ultrasound form nanoarchitectonic magnetic crystals a mesoporous @ manganese dioxide (m-Fe3O4@MnO2) hybrid nanostructure. The nanocomposite rapidly produced based on nucleation and growth pure iron-oxide nanocrystals in electrochemical system. pure, highly amorphous, nature; spherical shape, an average diameter 45 ± 10 nm MnO2-plane length 420 30 nm. stability m-Fe3O4 enhanced from 89.61 94.04% negligible weight loss after adding stable formation Based superior results material, it as anode material Li-ion batteries. m-Fe3O4@MnO2 nanostructure had active surface area, which interfacial interaction between metal surface; delivered 1513 mAh g−1 1290 first specific discharge charge capacity, respectively, 85% coulombic efficiency, showed excellent cyclic reversibility 660 efficiency almost 99% at current density 1.0 A g−1.
