摘要

采用水热法通过添加Ce离子制备了MnO2纳米空心球电极材料。Ce离子对MnO2的形貌和结晶程度有很大的影响

添加Ce离子后生成由纳米棒组成的中空球

中空球比表面积(BET)达到315.2 m2·g-1。MnO2电极电化学测试结果表明:当铈锰摩尔比为0.2时电极材料具有较好的电化学性能

其比电容达到178.6 F·g-1

与未加Ce离子相比其比电容提高了2.6倍

而且经过1000次循环稳定性测试后比电容仍保留了90.5%。这些结果表明添加Ce离子有利于形成中空结构

并提高了MnO2电极的比电容。

Abstract

Electrode material of MnO2 hollow nanosphere was synthesized via a simple hydrothermal process in the presence of Ce ion. Ce ion played a crucial role in controlling the morphology and crystalline structure of MnO2. The hollow nanosphere consisted of nanorods

and Brunauer-Emmet-Teller (BET) specific surface area of the hollow nanosphere was 315.2 m2·g-1. Electrochemical behavior of MnO2 electrode material was measured by cyclic voltammetry and galvanostatic charge-discharge. Better electrochemical properties of MnO2 electrode could be obtained when mole ratio of Ce to Mn was 0.2

and specific capacitance of as-prepared MnO2 electrode was 178.6 F·g-1

2.6 times higher than MnO2 electrode without Ce ions. Moreover

MnO2 electrode exhibited remarkable cyclability

and specific capacitance retained 90.5% even after 1000 cycles. Ce ion was favorable for forming a hollow structure

and improved specific capacitance of MnO2 electrode.
