CO2 was decomposed completely (100%) at 290-350°C with the oxygen deficient magnetite which had been prepared by passing the H2 gas through the magnetite powder at 290-350°C. In this reaction, oxygen in CO2 is transferred into the spinel structure of the oxygen-deficient site, and carbon is deposited on the surface of the magnetite. The activation energy estimated from Arrhenius plot is 75.0 kJ. When the carbon deposited on the magnetite was reacted with H2O (400°C) and H2 (300-500°C), H2 and CH4 were generated, respectively. The reactions found in this study will open the door to construct the chemical heat pump which can be applied to the power station to reduce the CO2 emission.
