Abstract

The Carbon Dioxide is the gas, which causes green house effects, unusual changes in the weather, destruction of the life. Almost every nation in the world is trying to search the countermeasure to this poisonous gas. I synthesized Fe_3O_4 and NaOH, in order to decompose the Carbon Dioxide. Among the particles synthesizing Fe_3O_4, I chose the equivalent ratio 1.00 which can decompose the Carbon Dioxide best, and fixed that equivalent ratio and added the 0.005~3.00 mole percentage of NiCl_2 and synthesized Fe_3O_4. I studied the decomposition of the Carbon Dioxide and methanized reaction, by measuring its crystal structure, thermochemistrical character and specific surface area. In decomposing the Carbon Dioxide, I used oxygen-deficit Magnetite which I produced by injecting the hydrogen gas into the synthesized sample. I observed the methanization reaction by raising the temperature of sample up to 650℃ and having it reacted with the hydrogen gas. The decomposition of the Carbon Dioxide was added 0.005, 0.03, 0.05 mole percentage of NiCl_2 was more effective than pure Fe_3O_4. All sample in which the decomposition of the Carbon Dioxide took place produced the methane gas.
