摘要

通过水热法制备了α-MoO₃纳米棒前驱体,再通过退火的方式制备出超长α-MoO₃纳米棒(10μm),采用超声法将α-MoO₃纳米棒锚定在氧化石墨烯(GO)纳米网之间,制备三明治结构的GO@MoO₃纳米材料,对其进行物相形貌分析和电化学测试。实验结果表明,根据恒电流充放电曲线,GO@MoO₃电极在1A/g时显示出高达370F/g的高比容量,远高于原始MoO₃电极214F/g的比容量;根据循环伏安曲线,与原始的MoO₃电极相比,GO@MoO₃电极表现出显著增强的比电容,在5、10、20、30、40和50mV/s下,比电容可分别高达805、594、479、430、394和355F/g)。

Abstract

The α-MoO₃ nanorod precursors were prepared by hydrothermal method,and then the ultra-long α-MoO₃nanorods (10 μm) were prepared by annealing,and the sandwich structure GO@MoO₃ nanomaterials were prepared by anchoring the α-MoO₃ nanorods between the graphene oxide nanowebs by ultrasonic method.The physical phase morphology analysis and electrochemical tests were performed.The specific capacity calculated from the constant current charge-discharge curve showed that the GO@MoO₃ electrode had a high specific capacity of 370F/g at 1A/g,which was much higher than that of the original MoO₃ electrode of 214F/g.The specific capacity calculated from the cyclic voltammetry curve revealed that the GO@MoO₃ electrode exhibited a significantly enhanced specific capacitance compared with the original MoO₃ electrode,and the specific capacitance could be up to 805,594,479,430,394,and 355F/g at 5,10,20,30,40,and 50mV/s,respectively.
