Abstract

Mn₁Ce₁ and Mn_0.9Co_0.1Ce₁ 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. Mn_0.9Co_0.1Ce₁ has higher activity than Mn₁Ce₁, indicating doping of Co to Mn-Ce-O complex can improve the catalytic activity.
