Effect of Pr, Mn doping on the structure and properties of BiFeO3

The powders of Bi1-xPrxFeO3 (x = 0, 0.05, 0.1) and Bi0.95Pr0.05Fe1-yMnyO3 (y were prepared by hydrothermal method. effects Pr Mn doping content on the structure, morphology, magnetic, photocatalytic properties BiFeO3 (BFO) have been studied. X-ray diffraction (XRD) demonstrated that compounds are distorted rhombohedral perovskite structure without any other heterogeneity structural transition. Field emission scanning electron microscope (FESEM) reflected surface is a dense, agglomerated sphere, morphology changes with addition Pr, Mn. Energy spectrum analysis (EDS) shows Bi0.95Pr0.05Fe0.95Mn0.05O3 sample mainly composed 5 elements (Bi, Fe, O, Mn), atomic ratio matches formula well. Integrating vibrating magnetometer (VSM) into physical property measurement system (PPMS-9) introduction Pr3+and Mn2+ ions can enhance magnetic BFO at room temperature. In addition, Pr3+ improve performance BFO, increase concentration, first rises then decreases, its catalytic getting better better.
