In situ Observation of the Coupling phenomenon between Iron Oxide and Carbon and the identification of the reaction species.

在这一年里，进行了以下新的实验，并获得了几个新的结果。新的实验(1)对赤铁矿进行了碳离子注入。(2)对赤铁矿进行了XPS测量，以阐明Fe-C-O之间化学键的变化。(3)原位观察了注入到赤铁矿中的碳的高温行为。通过这些实验，赤铁矿中Fe-C-O原子之间的化学键从表面逐渐改变。C-C键的存在在1μm~2μm附近出现最大值，C-O键和C=O键所占比例较高。在深度大于2μm的区域，Fe-C键增加，说明注入到赤铁矿中的碳增加了与Fe原子的相互作用，而不是O原子。

In the present year, following new experiments were carried out and several new results were obtained. Those resu lts will be published in the future.The new experiments(1) Carbon ion implantation into hematite was carried out.(2) XPS measurement on the hematite was carried out to clarify the variation of chemical bonding among Fe-C-O.(3) In situ observation of high temperature behavior of the carbon implanted into hematite were preformed.From these experiments, Chemical bonding among Fe-C-O atoms in the hematite were gradually changed from the surface. The existence of C-C bond showed a maximum value around 1μm to 2μm, the proportions of C-O bonding and C=O bonding were relatively high. In the region deeper than 2μm, Fe-C bonding was increased, which meant that the carbon implanted into hematite increased the interaction with Fe atom rather than O atom.
