Chemical Grafting-derived N, P Co-doped Hollow Microporous Carbon Spheres for High-Performance Sodium-ion Battery Anodes

The recent progress of pitch-based carbon anodes in sodium-ion batteries

“…Typically, the pores introduced by physical/chemical activation are mainly micropores (<2 nm), which can provide large surface area and ample adsorption sites for Na ion storage, thus enhancing surface capacitance contribution. Through template carbonization strategy, mesopores (2-50 nm) and macropores (>50 nm) can be constructed, which can facilitate the accessibility to electrolyte and provide channels for rapid ion transport/diffusion, leading to the improvement of rate capability [38,42,43].…”

1D confined materials synthesized via a coating method for thermal catalysis and energy storage applications

“…Compared with other synthesis strategies, the coating method is more robust and has a much higher trapping efficiency of the guest NPs. This is because a layer of host materials such as SiO 2 , 17 NiCo 2 O 4 , 22 TiO 2 , 23,24 RuO 2 , 25 and CeO 2 , 26,27 as well as NiCo silicate 28,29 or carbon 30–36 can be easily and uniformly coated and modified upon the guest NPs regardless of their shape and size.…”

Amidst these 1D conned materials synthesized via the coating method, CeO 2 , 26 SiO 2 , [37][38][39][40][41] and TiO 2 NT conned catalysts have been intensively studied for high temperature catalytic reactions such as the CO 2 (dry) reforming of methane (DRM) reaction, 42 partial oxidation of methane (POM), 37 water gas shi (WGS) 43 reaction etc.…”

“…During carbon coating, polymers such as poly-dopamine (PDA), resorcinol formaldehyde resin (RF), polyaniline (PANi), and polypyrrole (PPY), as well as glucose, and metal organic frameworks (MOFs) are the most frequently applied carbon precursors to prepare 1D carbon conned electrode materials. [30][31][32][33][34][35][36] Additionally, 1D electrode materials can also be directly coated with pre-synthesized carbon materials for instance GO/rGO with the help of surfactants.…”

Study of the Secondary Heteroatoms Doping on Nitrogen‐Doped Carbon and Their Oxygen Reduction Reaction Performance Evaluation

“…[27] Previous results demonstrated that DA derived carbons undergo defect creation rapidly and possess disordered sites which promotes an excellent ORR activity. [28,29] Based on these facts, we selected DA as a primary N source and followed by secondary heteroatoms P, B, and S precursors namely phytic acid, boric acid, and thiophene, respectively.…”
