Carbon dioxide can be decomposed into carbon almost completely (-100%) with the activated magnetite at 300°C. The activated magnetite is obtained by treating magnetite powder with H<SUB>2</SUB> gas at 300°C. Chemical analysis and the X-ray diffractometry showed that the activated magnetite is the oxygen-deficient magnetite (Fe<SUB>3+</SUB> δO<SUB>4</SUB>: δ=0.122). The CO<SUB>2</SUB> decomposition reaction is considered to proceed associated with the incorporation of the O<SUP>2-</SUP> ion of CO<SUB>2</SUB> into the oxygen-deficient site in the magnetite. We discussed the application of this new method to the closed ecological life support systems (CELSS) in space craft. A higher efficiency of the gas recycling system using this method is expected compared to that where the BOSCH reaction is adopted.
