摘要: Carbon-based materials were prepared to catalyze the V 3+/V 2+ couple of vanadium redox flow battery using chitosan as the preliminary material and FeCl 3 as activating agent. Graphite microcrystals were the main structures of the obtained catalyst (CTS-Fe-900) activated by FeCl 3, and they contained a large number of curled and overlapped carbon nanosheets. Compared with CTS-D-900 (without FeCl 3 as an activating agent), CTS-Fe-900 exhibits a better structure, higher graphitization degree, stronger current response, and …
