中文摘要：

采用氧化还原法以Bi纳米球和KMn O4为反应物制备BiOCl/MnO_x复合材料.利用X射线粉末衍射（XRD）、扫描电镜（SEM）和透射电镜（TEM）等表征手段对不同条件下所制备样品的物相和形貌进行表征,探究复合材料BiOCl/MnO_x的电化学性能.实验结果表明：BiOCl/MnO_x复合材料由纳米片组装的小球和不规则的片状物组成.随着KMnO_4用量的增加,BiOCl/MnO_x复合材料中不规则的片状物逐渐减少,规则的自组装小球状结构逐渐增多,形貌和尺寸变得比较均匀单一,复合材料的锂离子存储能力和循环稳定性变好.

英文摘要：

BiOCl/ MnOx composites have been successfully synthesized via a redox reaction of Bi spheres and KMnO4 . The obtained products of BiOC^MnOx composites were characterized by x-ray powder diffraction （XRD ） ,scanning electron microscope（ SEM ） and transmission electron microscopy （ TEM ）. In addition, the electrochemical properties of BiOCl / MnOx composite have been explored. Experimental results showed that BiOC/MnOx composite was made up of some spheres constructed by the assemble of nanosheets and some ir -regular flakes. With the increment of KMnO4 content, irregular flakes gradually reduced, while the self-assembly sphere-like structure gradually increased. The morphology and size became more uniform. BiOC /MnOx com-posite materials showed better storage capacity and cycle stability.
