The oxygen fugacity of CO 2 ---H 2 gas mixtures were measured with a ZrO 2 oxygen sensor at high temperatures in a furnace. We confirmed that the oxygen fugacity values measured by the ZrO 2 cell are more reducing than those of the CO 2 ---H 2 gas mixtures calculated by using JANAF data at temperatures below 1150°C as was previously reported by Huebner (1975). We successfully decreased the deviation of the measured oxygen-fugacity value from the calculated one down to temperature of 800°C by using a Pt catalyst. Our results suggest that the deviation is probably due to incomplete equilibration of the gases.
