摘要
采用溶液燃烧法制备层状多孔结构MnO_(2)-CeO_(2)纳米复合材料。催化氧化实验表征产物结果表明,相较于纯CeO_(2),MnO_(2)-CeO_(2)纳米复合材料催化氧化CO性能明显提升:当复合材料(MnO_(2))所占百分比为30%时,CO的转化温度最低,有望成为低成本高性能的新型CO催化剂。
Porous layered MnO_(2)-CeO_(2) nanocomposites were synthesized using a solution combustion synthesis route.Catalytic oxidation experiments were used to demonstrate the advantages of MnO_(2)-CeO_(2) nanocomposites compared with pure CeO_(2) in catalytic oxidation of carbon monoxide.It is confirmed that when the percentage of manganese dioxide is 30%,the conversion temperature of carbon monoxide is the lowest.It is expected to be a new carbon monoxide catalyzer with a low cost and high performance.
