One-step synthesis of nitrogen and sulfur co-doped hierarchical porous carbon derived from acesulfame potassium as a dual-function agent for supercapacitors and lithium‑sulfur batteries

Salt-assisted synthesis of advanced carbon-based materials for energy-related applications

“…219 Xiu et al prepared N, S-co-doped hierarchical porous carbon derived from acesulfame potassium as a dual-function agent, which showed excellent performance in supercapacitors and lithium ion batteries. 220 Using ammonium ferric citrate as the Fe 3 O 4 /carbon precursor and graphene oxide as the structure-directing agent, Fan et al synthesized Fe 3 O 4 @carbon nanosheet composites through a hydrothermal process followed by a subsequent carbonization. The Fe 3 O 4 @carbon nanosheet composites showed excellent specific capacitance of 586 F g −1 , 340 F g −1 at 0.5 A g −1 and 10 A g −1 .…”
