“…Hereon, the vibration bands around 595, 445 and 481 cm −1 are attributed to the stretching of the Mn–O bonds in Mn 3 O 4 NPs and MnO x /Mn 3 O 4 –rGO HNCs. 29,30 The presence of the Mn–O stretching vibration on the HNCs suggests the successful integration of the MnO x /Mn 3 O 4 with the rGO. These FT-IR results also advocate that the MnO x /Mn 3 O 4 nanostructured materials are embedded within the rGo nanosheets.…”

“…It was suggested that the methylene blue intercalated MnO 2 showed higher electro catalytic activity than non-intercalated MnO 2 . Hausmannite manganese oxide/reduced graphene oxide nanocomposite were synthesized and evaluated the dye degradation efficiency [15]. It shows that the nanocomposite has good efficiency than the pure manganese oxide.…”

Manganese oxide nanomaterials (Mn3O4) have been prepared from manganese salts of two different anions and studied the role of metal precursor. Manganous sulphate monohydrate and manganese oxalate were used as manganese metal precursors. The obtained Mn3O4 samples were characterized by x‐ray diffraction, transmission electron microscope, Fourier transform infrared spectroscopy, UV‐vis absorbance spectra and photoluminescence excitation spectra. The x‐ray diffraction reveals that the prepared nanoparticles are crystalline in nature with tetragonal structure. In addition, the x‐ray diffraction concludes that the lattice parameters were altered with change in the precursors. The transmission electron microscope exhibits the prepared manganese oxide particles were nano in scale between the ranges of 25 nm to 60 nm. The Fourier transform infrared spectrum confirmed the presence of manganese oxide. The luminescence intensity of the samples varies depending upon the precursors used. The sample comprising of mixed precursors shows higher luminescence intensity than the samples containing MnSO4 ⋅ H2O and MnC2O4 precursors. This is owing to the fact that the surface of the sample has a lower concentration of hydroxyl ions, which was confirmed from the Fourier transform infrared spectra.

A novel, well‐designed, silica‐supported magnesium ferrite nanorods were successfully developed at room temperature using the co‐precipitation method. The synthesized nanorods show an optical band gap of 3.1 eV, with the maximum wavelength absorptive at 334 nm. The average particle size is 36 nm with the FCC crystal structure by the X‐ray Diffraction technique (XRD). TGA achieved thermal stability of targeted mesoporous materials at 600°C. Field Emission Scanning Electron Microscopy (FE‐SEM) and High‐Resolution Transmission Electron Microscopy (HR‐TEM) techniques confirm the rod‐like structure. Energy Dispersive Spectroscopy (EDS) and X‐Ray Fluorescence (XRF) studies reveal the presence of all elements in the composition. The synthesized nanorods are highly magnetic by the vibrating sample magnetometer (VSM) technique, which shows a high coercivity value, that is, MgFe2O4@SiO2 is photocatalytically active. From BET analysis, the surface area, pore volume, and pore diameter are 19.2 m2 g−1, 2.46 cm3 g−1, and 5.10 nm, respectively. The experimental outcomes predict that the degradation efficiency (79%) of methyl orange dye was accomplished using MgFe2O4SiO2 nanorods within 270 min.
