“…Mn 3 O 4 as a magnetic material has gained siginificant attention due to its wide range of applications, such as high-density magnetic storage media, catalyst, ion exchange, molecular adsorption, electrochemical materials [1][2][3][4][5]. As a nanomaterial, Mn 3 O 4 NPs with remarkbly increased surface area and different morphologies are expected to exhibit better performance in all the above-mentioned applications.…”

Abstract:We report on the synthesis of Mn 3 O 4 nanoparticles (NPs) using a novel sonochemical method without requiring any pH adjustment.Synthesized material was identified as tetragonal hausmannite crystal structure model of Mn 3 O 4 from XRD analysis. Crystallite size was estimated from x-ray line profile fitting to be 17±5 nm. FTIR analysis revealed stretching vibrations of metal ions in tetrahedral and octahedral coordination confirming the crystal structure. TEM analysis revealed a dominantly cubic morphology of NPs with an average size of ~20 nm. Magnetic evaluation revealed a blocking temperature, T B of 40 K above which the material behaves paramagnetic. Asymmetric coercive field is attributed to the interaction between ferromagnetic Mn 3 O 4 and antiferromagnetic Mn oxide at the surface of nanoparticles.

“…Some strategies have been proposed to improve its electrochemical performance. Co doped Mn 3 O 4 have better cycle stability than undoped Mn 3 O 4 , with a capacity is only 400 mA h g -1 at a current density of 33-55 mA g -1 [3]; Gao et al [4] have prepared spongelike nanosized Mn 3 O 4 by precipitation method with a stable reversible capacity of 800 mA h g -1 after 40 cycles at a current rate of 0.25 C. In this paper, we have employed a facile and fast one-step solvothermal method to prepare Mn 3 O 4 /CNTs composite and evaluated its electrochemical performance as anode for lithium-ion batteries. We also used X-ray diffraction and scanning electron microscopy to characterize the structure and morphology of Mn 3 O 4 /CNTs composite.…”

Transition metal oxides especially manganese oxides are being intensively studied as candidate anode materials for next generation lithium ion batteries in high efficiency energy storage applications. In this paper, Mn3O4 /CNTs composite is prepared via a facile one-step solvothermal method. The results of XRD and SEM showed that Mn3O4 uniformly coated on the surface of CNTs. It could deliver a reversible charge capacity of 809.9 mA h g -1 at the current density of 40 mA g -1 , and the specific discharge capacity slightly increased from 644.2 mA h g -1 to 796.1 mA h g -1 after 50 cycles at a current density of 160 mA g -1 demonstrating excellent cycling stability.

“…Manganese (II, III) oxides (Mn 3 O 4 ) is an excellent example of TMOs which gained significant attention among researchers due to its wide range of applications in magnetic materials, catalysis, ion exchange, magnetic data storage, super capacitors, molecular adsorption and ferrite materials [2][3][4][5][6][7][8]. Mn 3 O 4 shows a paramagnetic behaviour at room temperature and ferromagnetic below 41-43K.…”
