(A) Cyclic voltammogram with a 0.1 V s⁻¹ scan rate on GO, T-rGO, and IC-rGO-modified glassy carbon electrode (GCE). (B) Constant current charge/discharge curves of T-rGO and IC-rGO. (C) Cyclic stability of IC-rGO at 10 A g⁻¹; the insert shows the charge discharge curves at different stages of the cycle life testing. (All experiments were performed in a three-electrode cell in 0.5 M H₂SO₄). (adapted from ref. [78], with permission from Royal Society of Chemistry 2017).
