摘要:
石墨烯具有导电率高、比表面积大以及机械性能优良等特性,因此在超级电容器领域具备极佳的应用前景,但纯石墨烯活性电极材料又面临着比容量相对较低的问题。文章通过一步水热法将零维(0D)二氧化钼(MoO2)纳米点修饰在2D石墨烯纳米片上,组装形成3D多孔复合材料,实现了0D-2D-3D多尺度材料的构建,并研究了以其作为超级电容器活性电极材料的电化学性能。结果表明,在2 mV/s扫速下,该纳米复合材料的比容量高达499 F/g,显示出优越的容量特性。
Abstract:
Due to the fact that graphene possesses high conductivity, large specific surface area and excellent mechanical properties, it has excellent application prospects in the field of supercapacitors. However, when it's directly used as the active electrode materials of supercapacitors, pure graphene face the problem of relatively low specific capacitance. In this paper, 3D porous nanocomposites composed of 2D graphene nanosheets, which was modified by 0D molybdenum dioxide(MoO2)nanodots,were synthesized by one-step hydrothermal method. And the electrochemical properties of this kind of 0D-2D-3D multi-scale composites were studied as the active electrode materials of supercapacitors. The results showed that the specific capacitance was as high as 499 F/g at 2 mV/s, displaying excellent capacity performance.
