Abstract	In order to screen one suitable catalyst for magnetically stabilized fluidized bed (MSFB) reactor in the process of oxidative carbonylation of phenol to diphenyl carbonate (DPC), Pd/MFe2O4 catalysts were chosen, then prepared and characterized by XRD, H2-TPR, XPS and vibrating sample magnetometer (VSM). Compared to the other metal ion doped spinel ferrite catalysts, the catalytic activity of Pd/MnFe2O4 was much higher, which the single pass yield of DPC reached 33.12% with selectivity above 99%, and turnover frequency (TOF) reached 70.56 molDPC·(molPd·h). The result showed that the formation of the ferrite oxygen-deficient and ion transference in the ferrites was in favor of the catalytic activity. When the support MnFe2O4 was calcinated at 500 °C, the saturation magnetization of the obtained catalyst Pd/MnFe2O4 came up to 43.1 A·m·kg. With good magnetic property and brilliant catalytic activity the catalyst Pd/MnFe2O4 may suite for industrial experiments in MSFB reactor in future.
