The precursor of perovskite-type La0.5Pb0.5MnO3 oxide was prepared by co-precipitation method in rotating packed bed (RPB).The effects of rotating speed of RPB
flow rates of reactants and the addition of PEG10000 on properties of La0.5Pb0.5MnO3 powder were investigated in combination with XRD
BET and SEM techniques.The results showed that the suitable conditions for preparation of precursor were as follows: rotating speed of 1200 r·min-1
reactants flow rate of 80 L·h-1 and PEG10000 as disperser.The corresponding La0.5Pb0.5MnO3 powder obtained by calcined was used as supports for Pd- catalytic synthesis of diphenyl carbonate(DPC) and showed good performance.The yield of DPC could achieve 13.30% when reaction temperature was 65℃
