摘要：

The CO2 decomposition into carbon with the rhodium-bearing activated magnetite (Rh-AM) was studied in comparison with the activated magnetite (AM). The Rh-AM and the AM were prepared by flowing hydrogen gas through the rhodium-bearing magnetite (Rh-M) and the magnetite (M), respectively. The rate of activation of the Rh-M to the Rh-AM was about three times higher than that of the M to the AM at 300-degrees-C. The reactivity for the CO2 decomposition into carbon with the Rh-AM (70% CO2 was decomposed in 40 min) was higher than that with the AM (30% in 40 min) at 300-degrees-C. The Rh-M was activated to the Rh-AM at a lower temperature of 250-degrees-C, and the Rh-AM decomposed CO2 into carbon at 250-degrees-C. On the other hand, the M was little activated at 250-degrees-C.
