Using foam ceramics as carrier,manganese oxide solid phase catalyst has been prepared by impregnation method. The effects of different species and concentrations of the dipping solution on the loading capacity and stability of solid phase catalyst are investigated. The solid catalyst is characterized by scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). And combined with ozone,experimental research on catalytic degradation of phenol has been conducted. The results show that the load rate of using 0.5 mol/L Mn (NO3)2 of impregnation liquid is the highest,reaching 2.32%,and its stability is the best. The phenol degradation rate by using the prepared man-ganese-loaded solid phase catalyst can reach 89.6%and the corresponding COD degradation rate reaches 79.2%.
