Abstract

Atmospheric pressure plasma (APP) generates highly reactive species that are useful for surface activation. We demonstrate a fast regeneration of iron oxides, that are popular catalysts in various industrial processes, using microwave-driven argon APP under ambient conditions. The surface treatment of hematite powder by the APP with a small portion of hydrogen (0.5 vol%) lowers the oxide's reduction temperature. A near-infrared laser is used for localized heating to control the surface temperature. Controlled experiments without plasma confirm the catalytic effect of the plasma. Raman, XRD, SEM, and XPS analyses show that the plasma treatment changed the chemical state of the hematite to that of magnetite without sintering.

摘要

大气压等离子体（APP）会产生对表面活化有用的高活性物质。我们展示了在环境条件下，使用微波驱动的氩气APP对各种工业过程中常用的催化剂——氧化铁进行快速再生。用含有少量氢气（0.5体积%）的APP对赤铁矿粉末进行表面处理，可降低氧化物的还原温度。使用近红外激光进行局部加热以控制表面温度。无等离子体的对照实验证实了等离子体的催化作用。拉曼光谱、X射线衍射、扫描电子显微镜和X射线光电子能谱分析表明，等离子体处理将赤铁矿的化学状态转变为磁铁矿的化学状态，且没有发生烧结。
