Formation of mesoporous Co/CoS/Metal-N-C@S, N-codoped hairy carbon polyhedrons as an efficient trifunctional electrocatalyst for Zn-air batteries and water splitting

Activity Promotion of Core and Shell in Multifunctional Core–Shell Co2P@NC Electrocatalyst by Secondary Metal Doping for Water Electrolysis and Zn‐Air Batteries

“…Besides, the electrocatalytic HER/OER/ORR activity of Fe-Co 2 P@Fe-N-C catalyst can be comparable to that of most reported transition metal-based trifunctional electrocatalysts (Figure 3a; Tables S1-S3, Supporting Information), [13,[35][36][37][38][39][40][41][42][43][44][45][46] showing its considerable potential for future electrocatalytic applications. Generally, a good long-term electrochemical stability is also extraordinarily important for electrocatalysis.…”

“…Encapsulating TMPs into nitrogen-doped carbon materials (TMPs@NC) has been regarded as a promising strategy to enhance activity and stability, especially for HER electrocatalysis. [10][11][12][13] However, due to the lack of necessary active sites, TMPs@NC often shows poor oxygen electrochemical activities for OER/ORR, which severely hinders their multifunctional applications for integrated or reversible electrochemical energy-conversion systems.…”

Molecule-assisted modulation of the high-valence Co3+ in 3D honeycomb-like CoxSy networks for high-performance solid-state asymmetric supercapacitors

“…Among the numerous strategies proposed, metal-organic framework (MOF) self-templating method has been emerged as an especially fascinating approach. MOFs are a combination of metal ions and organic ligands with ordered tunnels [22,25], and the MOF-derived materials can maintain the architectures of pristine MOFs, achieving well-organized and customizable structures, adjustable pores and large specific surface areas [26]. In addition, the metal ions can be effectively confined by the organic frameworks, which can be further transformed to transition metal-based derivatives [12].…”

New types of hybrid electrolytes for supercapacitors

“…In recent years, aqueous electrolytes have been widely explored for electrochemical energy storage [26,[56][57][58]. Compared with ILs and organic electrolytes, aqueous electrolytes are inherently safe and easy to handle.…”
