In this research, tris(hydroxymethyl)aminomethane-functionalized graphene oxide (GO@T) with high specific capacitance and cyclic stability was synthesized and investigated. Density functional theory calculations were used to study the properties of GO and GO@T.
In this research, graphene oxide (GO) functionalized with tris(hydroxymethyl)aminomethane (T) was synthesized with a simple one-pot method, and applied as an electrode material for supercapacitors. Electrochemical measurements on the synthesized tris(hydroxymethyl)aminomethane-functionalized graphene oxide (GO@T) indicated a specific capacitance of 549.8 F g(-1) at a specific current of 2.5 A g(-1) and a specific capacitance of 358 F g(-1) at a specific current of 7 A g(-1) in the potential range of-0.5-0.5 V versus Ag/AgCl. It also showed a high cyclic stability. According to the results, 80 and 68% of the initial capacitance was retained after 5500 and 9300 cycles, respectively. Density functional theory calculations were used to investigate the quantum capacitance, free energy change during functionalization reaction, and the layer distance of GO and GO@T.
