Defect-rich and ultrathin N doped carbon nanosheets exhibited low overpotentials robust stability for simultaneous ORR, OER HER.
Abstract The primary bottleneck hindering the application of hard carbon in sodium‐ion batteries (SIBs) anodes lies its inadequate initial Coulombic efficiency (ICE). Unclear causes capacity loss at microscopic level restrict improvement anodes. Here, two pivotal stages that influence structure and composition carbon, namely synthesis, storage are evaluated; subsequently identifying crucial determinants contributing to irreversible loss. results suggest undergrown layers allowing intrusion...
Abstract Hard carbon is regarded as a promising anode candidate for sodium‐ion batteries due to its low cost, relatively working voltage, and satisfactory specific capacity. However, it still remains challenge obtain high‐performance hard from cost‐effective sources. In addition, the solid electrolyte interphase (SEI) subjected continuous rupture during battery cycling, leading fast capacity decay. Herein, lignin‐based with robust SEI developed address these issues, effectively killing two...
In this study, WO3 nanoplates modified by doping with gadolinium (Gd) were synthesized a hydrothermal method. The effect of the rare-earth element on photoelectrochemical (PEC) performance one- or two-dimensional (2D) materials was examined. Scanning electron microscopy, transmission and X-ray diffraction employed to examine crystal phase morphology Gd-doped thus prepared. Results UV–vis spectroscopy, valence-band (VB) photoelectron Mott–Schottky analyses indicated that conduction band VB...
Conducting polymer with 1D nanostructure exhibits excellent electrochemical performances but a poor cyclability that limits its use in supercapacitors. In this work, novel composite electrode made of polyaniline nanowire–titania nanotube array was synthesized via simple and inexpensive route by electropolymerizing aniline onto an anodized titania array. The specific capacitance as high 732 F g−1 at 1 A g−1, which remained 543 when the current density increased 20 times. 74% maximum energy...
Ternary Cu–Sn–S chalcogenides, Cu2SnS3, Cu5Sn2S7 and Cu3SnS4, have been successfully synthesized by annealing three precursor film samples deposited via a modified successive ionic layer adsorption reaction (SILAR) method. The mechanism of ion-exchange improvement the rinsing procedure were introduced into SILAR process for purpose achieving codeposition different metal sulfides increasing growth rate thin films. crystal structure, composition, surface morphology, optical electrical...
High-performance Li-rich layered oxide (LRLO) cathode material is appealing for next-generation Li-ion batteries owing to its high specific capacity (>300 mAh g–1). Despite intense studies in the past decade, low initial Coulombic efficiency and unsatisfactory cycling stability of LRLO still remain as great challenges practical applications. Here, we report a rational design orthogonally arranged {010}-oriented nanoplates with built-in anisotropic Li+ ion transport tunnels. Such novel...

Presently, considerable attention has been paid to the Fe-based dichalcogenides as anode materials for sodium ion batteries (SIBs) due their abundant resources, chemical stability, and high theoretical capacity. In this paper, we make nanooctahedra particles assembled FeSe2 microspheres embedded into sulfur-doped reduced graphene oxide sheets through a one-step hydrothermal reduction route, in which of oxide, doping sulfur atoms, preparation FeSe2/sulfur-doped (FeSe2/SG) composites are...
Abstract Carbon dots have been recognized as one of the most promising candidates for oxygen reduction reaction (ORR) in alkaline media. However, desired ORR performance metal–air batteries is often limited by moderate electrocatalytic activity and lack a method to realize good dispersion. To address these issues, herein biomass‐deriving reported achieve situ phosphorus doping (P‐doping) carbon their simultaneous decoration onto graphene matrix. The resultant product, namely P‐doped...
Sodium-ion batteries (SIBs) show great potential as alternative energy storage devices for next generation systems due to the deficiency of lithium resources.
Electrochemical nitrogen reduction reaction (NRR) is a promising method for synthesizing ammonia (NH3). However, due to the extremely strong N≡N bond and competing hydrogen evolution (HER), electrochemical NRR process remains great challenge in achieving high NH3 yielding rate Faradaic efficiency (FE). Recently, either Bi-based or W-based catalysts have been used N2 fixation lower HER activity. To further promote activation, we develop simple protocol introduce adjust crystal defects host...
