Abstract :
Mn1Ce1 and Mn0.9Co0.1Ce1 complex oxides were prepared by co-precipitation in hydrothermal conditions and their physicochemical properties were characterized with N2 adsorption, XRD, Raman, and SEM. The complex oxides show enough stability and catalytic activity for oxidative degradation of 4,4´-Dibromobiphenyl in sub-critical water. Mn0.9Co0.1Ce1 has higher activity than Mn1Ce1, indicating doping of Co to Mn-Ce-O complex can improve the catalytic activity.
