摘要
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。
Nano manganese powder is prepared by the arc plasma method using raw manganesian ore.The structure and composition of nano manganese powder is analyzed by TEM,XRD and atom absorption.Nano manganese powder is loaded on γ Al 2O 3 support by mechanical means to make the supported nano catalyst, a CO oxidation catalyst.The results that nano catalyst catalyzes CO oxidation show that the activity of the supported nano manganese catalyst is as high as that of Pd catalyst.
