▎ 摘　　要

In this work, sodium cholate (NaC) was used as novel green reducing agent for graphene oxide (GO) reduction at 90 degrees C and short synthesis time using a continuous segmented flow reaction system. As a comparison, we had used the common reducing agent which is glucose to study its chemical and electrochemical properties. The morphologies of GO and reduced-graphene oxide (rGO) were characterized with X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscope (FESEM), Fourier transformed infrared (FTIR), Raman and Ultraviolet-Visible (UV-Vis) spectroscopy analysis demonstrated that reduction of GO occurred. For electrochemical measurements, the rGO was cast on carbon cloth to investigate the electrochemical performance with cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) measurements. NaC assisted rGO (rGO-NaC) was able to achieve a specific capacitance up to 94 F g(-1) at 0.1 A g(-1) and remarkable capacitance retention of 103% after 10,000 cycles. A flexible test shows that rGO-NaC bendable at 0 degrees-60 degrees. These results demonstrate that rGO-NaC is promising as flexible supercapacitors electrodes.
