以锰矿为原料，用电弧等离子体法制备纳米锰粉体。用ＴＥＭ、ＸＲＤ及原子吸收分析纳米锰粉体的结构和组成，用机械方法将纳米锰负载到Ａｌ２Ｏ３载体表面上，制成负载型纳米催化剂，用于催化ＣＯ氧化反应，显示出较高的催化活性。
Taking manganese ore as raw material, nano-manganese powder is prepared by arc plasma method. The structure and composition of the nano-manganese powder were analyzed by TEM, XRD and atomic absorption spectroscopy. The nano-manganese was loaded on the surface of Al2O3 support by mechanical method to form a supported nano-catalyst for the catalytic CO oxidation reaction and showed a high catalytic active.
