PREPARATION OF GRAPHENE MATERIAL WITH BENZIMIDAZOLE FRAGMENTS
Description
The new benzimidazole-functionalized graphene material based on graphene oxide (GO) and 3,3',4,4'- tetraaminodiphenyl oxide (TADPO) was obtained under one-step hydrothermal synthesis conditions. According to IR spectroscopy and elemental analysis, as a result of the reaction, benzimidazole (BI) rings are formed, and the mass content of nitrogen is 12.3%. The new graphene material is characterized by excellent electrochemical efficiency in a threeelectrode supercapacitor. As a result of the redox activity of BI cycles the specific capacitance reaches 286 F/g at the scan rate of 2 mV/s, which is substantially higher than the reduced graphene oxide (RGO) sample obtained under similar conditions without using TADPO (159 F/g at 2 mV/s)
