摘要
本文采用氧化还原沉淀法制备了MnO_2材料和Mn/Ce复合氧化物材料。研究结果表明,600℃烧结的M600材料为α-MnO2,具有一维纳米形貌,一致性好,在大电流密度放电时具有良好的电化学性能。400℃烧结的MC400材料为无定形态,具有疏松多孔形貌,为Mn/Ce氧化物的杂糅相,具有最佳的电化学活性和稳定性。
MnO_2 andMn/Ce composite oxide material were prepared by redox precipitation method.The results show that the M600 sintered at 600℃ is a-MnO_2 with an one-dimensional nanostructure,which has a good electrochemical performance at high discharge current density.The MC400 sintered at 400℃ is amorphousMn/Ce mixed oxide phase with a porous morphology,which has the best electrochemical activity and stability.
