Pseudocapacitance-rich carbon nanospheres with graphene protective shield achieving favorable capacity-cyclability combinations of K-ion storage

Photoelectrocatalytic activity of silicon nanowires decorated with electroless copper nanoparticles and graphene oxide using a plasma jet for removal of methyl orange under visible light

“…53,54 The peak i has been reported in the graphene production from graphitic materials. It is related to the intercalation of ions containing sulfur functional groups, 55,56 which could be associated with sulfate ions from sulfuric acid and potassium sulfate. 57,58 The nature of the deposited carbon material was also investigated through the chronoamperometry technique.…”

Advanced Electrode Materials for Potassium‐Ion Hybrid Capacitors

“…Heteroatom doping is a terrific way to modify graphene. [39] The synthesis of heteroatom-doped graphene usually adopts two methods: post-annealing and direct synthesis. During postprocessing, graphene or graphene oxide must be extracted first and then treated in NH 3 or other atmospheres.…”

An oriented tube array porous carbon anode prepared using a self-blowing mold of salt templates for high-rate potassium storage

“…Lithium-ion batteries (LIBs) have been commercialized as an advanced energy storage system due to their high energy density and stable cycling performance, but the scarcity of lithium resources limits their sustainable development in large-scale energy storage applications. 1–4 Compared with lithium, potassium resources are abundant and widely distributed, and with its lower standard redox potential and smaller Stokes radius, potassium achieves higher ionic conductivity and faster diffusion rates. 5–8 Therefore, K-based energy storage devices have received more and more attention and become one of the most competitive energy storage technologies.…”
