摘　　要：通过反胶束法结合简单的煅烧反应制备了二维纳米CoMnO_(4)材料。透射电子显微镜和扫描电子显微镜等对反胶束合成产物的分析表明:反胶束体系有效降低材料反应速率,可控地获得一维纳米针状、二维纳米片状、三维纳米花球状等CoMnO_(4)材料。对CoMnO_(4)二维纳米片的电化学测试表明:厚度仅10 nm的二维片状材料具备优异的比容量和倍率性能,在0.1 C下的可逆容量达到1035 mAh/g,3.2 C下也能保有224 mAh/g,且在0.8 C下能够稳定循环150圈以上。Two-dimensional CoMnO_(4) materials were prepared by the reverse micelle method combined with a simple calcination reaction.Transmission electron microscopy(TEM)and scanning electron microscopy(SEM)show that the reverse micelle system can effectively reduce the reaction rate of the material,and several CoMnO_(4) materials such as 1D nanospicules,2D nanosheets and 3D nanoflower spheres can be controllably obtained.The electrochemical test of 2D CoMoO_(4) nanosheets shows that the 2D sheet material with a thickness of only 10 nm has excellent specific capacity and magnification performance.The reversible capacity can reach 1035 mAh/g at 0.1 C,and can retain 224 mAh/g at 3.2 C,and also can reach a stable cycling of more than 150 times at 0.8 C.
