        For decompose carbon dioxide, manganese oxide was synthesized with 0.25M-MnSO4·nH2O and 0.5M-NaOH by coprecipitation. We made magnetite deoxidized manganese oxide by hydrogen reduction for 1hour at 330℃. We investigated characteristics of catalyst, hydrogen reduction degree and decomposition rate of carbon dioxide. The structure of the hausmannite certified spinel type. The specific surface area of synthesized hausmannite and deoxidized hausmannite were 22.36m2/g, 33.56m2/g respectively. The decomposition rate of CO2 of deoxidized hausmannite was 57%.
