Abstract
Radiation induced CO2 conversion to CO and hydrocarbon has been studie d using a solution suspended with iron powder and saturated with CO2. Due to the corrosion enhanced by gamma-rays, H-2 has become the most d ominant product of all. Corresponding to the rapid H-2 formation, a li ttle hydrocarbon containing less than 4 carbon atoms has been produced in the initial period of irradiation, whereas CO yield has gradually increased to a considerable amount over a prolonged irradiation period . The CO yield has also shown a marked increase associated with introd ucing Ni2+ or Cu2+ into the solution. It is understood that 5.6 hydrog en atoms are consumed in the termination reaction of H-2 formation.
