A simple and fast microwave assisted approach for the reduction of graphene oxide

Herein, a simple and fast method for chemical reduction of graphene oxides (GO) was carried out, the most common monosaccharide (glucose) here served as a green, non-toxic and high-effective reduction reagent. After reacted in an alkaline microwave-assisted environment for several hours, the water-soluble glucose reduced graphene oxide (GRGO) was obtained. Meanwhile, the as-prepared GRGO powders can be easily dispersed in several common organic solvents. And the colloidal solutions show no signs of agglomeration even after a week. The Raman spectra XRD and the TG analysis as well as other tests show the GO sheets were reduced successfully. The electrochemical testing results reveal that GRGO3-based flexible electrode has specific capacitance as high as 179 F g−1 at the potential scanning rate of 2 mV s−1. This environment friendly short-time microwave-assist solvothermal treatment is efficient and has a promising prospect of application.
