| 英文摘要 | the magnetite fe3o4+delta (0 less than or equal to delta less than or equal to 0.5) of different particle sizes were prepared using wet-heating oxidation method, supercritical fluid dry method and ferrous oxalate and ferric oxalate high-temperature decomposition method, and their structure were characterized by xrd, mossbauer spectra, ir spectra and stem. the oxygen-deficient magnetite of fe3o4+delta (0 < delta < 1) was prepared using h-2 reduction of fe3o4+delta (0 < delta < 0.5) at 573 k and its properties (lattice constant, magnetism, stability, and reduction ability) were studied ih detail. the activity of decomposing co2 with oxygen-deficient magnetite of different sizes were compared and the effects of degree of oxygen-deficiency, reaction time, and temperature on the activity of the decomposing co2 into carbon with oxygen-deficient magnetite were investigated. it is found that oxygen in the co2 was incorporated in the form of o2- into oxygen-deficient magnetite and co2 was reduced to carbon, at the same time fe3o4-delta converted into stoichiometric fe3o4. the smaller the particle size of magnetite is, the larger the oxygen-deficient degree is, the higher the reaction temperature is, and the higher the activity of decomposing co2 is.
