▎ 摘  要

In this work, reduced graphene oxide (RGO) was incorporated into NiWO4 to obtain the RGO/NiWO4 composites by a facile hydrothermal method. The supercapacitive properties of these composites were studied by cyclic voltammetry and galvanostatic charge/discharge. It is surprised that the RGO/NiWO4 composite exhibits twice specific capacitance and better stability than NiWO4. RGO acts as the conductive substrate for NiWO4 nanoparticles, which can not only inhibit the aggregations of the NiWO4 nanoparticles and RGO flakes to obtain the high specific surface area, but also improve the electrical conductivity to accelerate the charge transmission. Moreover, RGO is also an electrical double layer capacitor electrode material. Therefore, the RGO/NiWO4 composite is a good supercapacitive material.
