The powders of Bi1-xPrxFeO3 (x = 0, 0.05, 0.1) and Bi0.95Pr0.05Fe1-yMnyO3 (y = 0.05, 0.1) were prepared by hydrothermal method. The effects of Pr and Mn doping content on the structure, morphology, magnetic, and photocatalytic properties of BiFeO3 (BFO) have been studied. X-ray diffraction (XRD) demonstrated that the compounds are distorted rhombohedral perovskite structure without any other heterogeneity and structural transition. Field emission scanning electron microscope (FESEM) reflected

Energy spectrum analysis (EDS) shows that the Bi0.95Pr0.05Fe0.95Mn0.05O3 sample is mainly composed of 5 elements (Bi, Fe, O, Pr, Mn), and the atomic ratio matches the formula well. Integrating the vibrating sample magnetometer (VSM) into the physical property measurement system (PPMS-9) shows that the introduction of Pr3+and Mn2+ ions can enhance the magnetic properties of BFO at room temperature. In addition, doping with Pr3+ and Mn2+ ions can improve the photocatalytic performance of BFO, and with the increase of Mn2+ concentration, the photocatalytic performance of BFO first rises and then decreases, and its catalytic performance is getting better and better.
