Graphitic carbon nitride (g-C3N4) behaving as a layered feature with graphite was indexed high-content nitrogen-doping material, attracting increasing attention for application in energy storage devices. However, poor conductivity and resulting serious irreversible capacity loss were pronounced g-C3N4 material due to its high nitrogen content. In this work, magnesiothermic denitriding technology is demonstrated reduce the content of (especially graphitic nitrogen) enhanced lithium properties...
Novel g-C3N4/CoO nanocomposite application for photocatalytic H2 evolution were designed and fabricated the first time in this work. The structure morphology of investigated by a wide range characterization methods. obtained composites exhibited more-efficient utilization solar energy than pure g-C3N4 did, resulting higher activity evolution. optimum photoactivity under visible-light irradiation with CoO mass content 0.5 wt % (651.3 μmol h–1 g–1) was up to 3 times as high that (220.16 g–1)....
A series of single-composition trichromatic white-emitting Sr3.5Y6.5O2(PO4)1.5(SiO4)4.5 (SYPSO) : Ce3+, Tb3+, Mn2+ phosphors were investigated, and the crystal structures luminescence properties, especially energy transfer behavior, are discussed in detail. It was found that SYPSO can yield three major RGB emission bands visible spectral region: blue from 5d–4f transitions green 5D4–7FJ (J = 3, 4, 5, 6) Tb3+ red 4T1(4G)–6A1(6S) transition ions. The process between Ce3+ have both been...
A series of iso-structural green-emitting Na3(Y,Sc)Si3O9:Eu2+ phosphors with different Y/Sc ratios have been synthesized by a solid-state reaction. All the exhibited strong broad absorption bands in near ultraviolet (n-UV) range, and gave bright green emission upon 365 nm excitation light. As for composition-optimized Na3Y0.3Sc0.7Si3O9:Eu2+ phosphor, critical Eu2+ quenching concentration (QC) was determined to be about 3 mol%, corresponding QC mechanism verified dipole–quadrupole...
Ultrathin graphitic carbon nitride (UGCN) nanosheets with an extended region of visible light response and enhanced surface area were constructed for a significant enhancement in photocatalysis.
The combination of alkali metal electrodes and solid-state electrolytes is considered a promising strategy to develop high-energy rechargeable batteries. However, the practical applications these two components are hindered by large interfacial resistance growth detrimental depositions (e.g., dendrites) during cycling originated unsatisfactory electrode/solid electrolyte contact. To tackle issues, we propose room temperature ultrasound solid welding improve contact between Na Na3Zr2Si2PO12...
Abstract N‐doped carbons as one of the most prominent anode materials to replace standard graphite exhibit outstanding Li + storage performance. However, carbon anodes still suffer from low N‐doping levels and initial Coulombic efficiency (ICE). In this study, high graphitic‐N (LGNCs) with enhanced ICE were synthesized by taking advantage a denitrification strategy for graphitic nitride (g‐C 3 N 4 ). brief, more than 14.5 at% g‐C (55.1 N) was retained reacting lithium, which subsequently...
