- Abstract
We report the fabricating of BiFeO3 (BFO) and Mn-doped BFO is prepared by the commonly used sol–gel method and obtained various excellent properties. X-ray diffraction patterns present that BFO is a pure phase and no impurities are detected and demonstrated that Mn is successfully doped into the BFO crystal structure. X-ray photoelectron spectroscopy analysis suggested that the extent of Mn doping in the samples and check the enhancement of Fe3+ ions concentration in the nanoparticles. The results of scanning electron microscopy and transmission electron microscope indicated that the morphology and size of the nanoparticles with different Mn doping concentrations. The BFO nanoparticles exhibit weak ferromagnetic nature at general ambient temperature. However, the ratio of Mn ions to Fe ions changes to some extent, and the ferromagnetic behavior also changes, which is mainly due to the collapse of spin cycloid structure and the enhancement of super-exchange interaction between Fe–O–Fe, it can be inferred that Mn-doping has significant importance in increasing the ferromagnetic properties of BFO-based nanoparticles. The photocatalytic performance of Mn-doped BFO nanoparticles has also been further studied, which confirms the potential application value of Mn-doped BiFeO3 in the field of photocatalysis.
