摘要

采用两步水热法制备了超细氧化锡纳米棒/还原氧化石墨烯复合材料。用扫描电镜、x射线衍射仪和傅里叶变换红外光谱对所制备的纳米复合材料进行了表征。电化学性能测试结果表明，在1 M Na2SO4电解液中，当电流密度为100 mA g−1时，复合材料的比电容可达262.2 F g−1。经过6000次循环后，复合材料的初始电容保持率为96.1%，表明其具有良好的电化学性能。

The preparation and characterization of SnO2/rGO nanocomposites electrode materials for supercapacitor

The ultrafine tin oxide (SnO2) nanorods/reduced graphene oxide (rGO) composites are synthesized by a two-step hydrothermal method. The prepared nanocomposites are characterized by scanning electron microscope, X-ray diffractometer, and Fourier transform infrared spectra. The results of electrochemical performance show that specific capacitance of the composite can reach 262.2 F g−1 at the current density of 100 mA g−1 in the 1 M Na2SO4 electrolyte. An initial capacitance retention of the composite is 96.1% after 6000 cycles, indicating its excellent electrochemical performance.
