摘　　要：文章制备了钙钛矿型复合氧化物 Sr1 - x Cux Mn O3( x=0 .1～ 0 .5 ) ,考察了其在微波场中的温升行为 ,并以此为催化剂 ,考察了其在微波场中催化氧化 CO的活性。结果表明 :催化剂在微波场的温升行为受酸比的影响。本实验条件下当 X=0 .2 ,即 Sr0 .8Cu0 .2 Mn O3催化 CO氧化的活性最高。The Perovskite-type Oxides Catalysts Sr 1-xCu xMnO 3 ware prepared Temperature rising behavior of its ware studied. And the catalytic activity for CO oxidation reaction were investigated. Results showed that the temperature rising behavior of catalyst Sr 0.9Cu 0.1MnO 3 was the best in microwave field. The catalytic activity for CO oxidation of catalyst Sr 0.9Cu 0.1MnO 3 was the high.
