Synthesis and structural properties of manganese titanate MnTiO3 nanoparticle
Creators
Description
The nanosized manganese titanate (pyrophanite) MnTiO3 was prepared by oxidation of Mn(OH)2 with TiO2 (P-25) powder in cetyltrimethylammonium bromide (CTAB) micelle solutions and the calcinations of the produced powders. The nanostructure of pyrophanite was characterized with X-ray powder diffraction (XRD), transmission electron microscopy (TEM), UV-Vis spectroscopy and fourier transform Raman (FT-Raman) spectroscopy. The new absorption peaks in FT-Raman spectra indicate the formation of Ti-O-Mn bond. TEM images showed that the nanoparticles were almost spherical or slight stretched and the sizes are in the range of 40-60 nm. The UV-Vis results showed that nanosized MnTiO3 caused significant absorption shift to the visible region (320-750 nm) with a λmax 620 nm, compared to pure TiO2 powder
