영어 초록
The spinel LiMn2O4 powders were synthesized at 480℃ for 12 h in air by a sol-gel method using manganese acetate and lithium hydroxide as starting material and the Fe3O4 powders were synthesized by the precipitation method using 0.2M-FeSO4·H2O and 0.5M-NaOH. The synthesized Fe3O4 powders were mixed at portion of 5, 10, 15 and 20 wt% about LiMn2O4 powders through ball-milling followed by drying at room temperature for 48 h in air. The mixed catalysts were reduced at 350℃ for 3 h by hydrogen and the decomposition rate of carbon dioxide was measured at 350℃ using the reduced catalysts. As the results of CO2 decomposition experiments, the decomposition rates of carbon dioxide were 85% in all catalysts but the initial decomposition rates of CO2 were slightly high in the case of the 5%-Fe3O4 added catalyst.
