A stable MnOx @C@MnOx core-shell heterostructure consisting of vertical nanosheets grown evenly on the surface @carbon nanowires are obtained by simple liquid phase method combined with thermal treatment. The hierarchical electrode possesses a high specific capacitance 350 F g-1 and an excellent cycle performance owing to existence pore structure among ultrasmall nanoparticles rapid transmission electrons between active material carbon coating layer. Particularly, according in situ Raman...
Photocatalytic carbon dioxide (CO2) reduction is an emerging approach to synthesizing monoxide (CO) but still suffers from poor selectivity and low catalytic efficiency because of the high energy barrier toward *COOH formation. Herein, we report selective high-efficiency photosynthesis CO with a boron (B)- sulfur (S)-codoped graphitic nitride (g-C3N4) catalyst (B,S-CN), which shifts rate-determining-step (RDS) CO2 protonation adsorption. This realized by local mimicking frustrated Lewis...
A stable MnO2 nanowires@NiCo-layered double hydroxide (LDH) nanosheet core–shell heterostructure is prepared via a simple liquid-phase reaction method, in which the NiCo-LDH nanosheets grow uniformly on surface of ultralong nanowires with tunnel structure. Electrochemical studies indicate that electrode has high specific capacitances 708 and 630 C g–1 at 1 10 g–1, respectively, exhibits capacitance retention 82.3% after 2000 cycles. According to situ Raman spectral analysis, material...
A unique Co/Co 2 VO 4 composite with 2D–2D heterostructure provides excellent cycle stability at high current density as an anode material for LIBs, which is attributed to a proposed mechanism of “active center's charge transfer—capacity compensation”.
Manganese-based oxides are one of the most promising high-performance supercapacitor (SC) electrode materials. In this work, a stable MnO x nanowires@MnO nanosheets core–shell heterostructure material consisting grown uniformly on surface nanowires has been prepared by simple liquid phase method followed thermal treatment.

Abstract Transition metal vanadates (TMVs) have long been seen as promising anodes for lithium‐ion batteries (LIBs). To improve the electrochemical performance of them, designing rational nanostructures and utilizing synergetic effect multiple components are usually regarded two effective strategies. Herein, ultrathin porous hexagonal Zn 3 V O 8 /ZnO@N‐C (ZnVO@N‐C) nanoplates synthesized via a phase separation method which is achieved by changing annealing temperatures. Under temperature 650...
Manganese dioxide, the most representative cathode material for aqueous zinc-ion batteries (ZIBs), has a high theoretical specific capacity and moderate voltage platform. However, slow ion transport rate caused by strong electrostatic interaction between Zn 2+ host material, inherently poor electrical conductivity of manganese dioxide are current challenges remaining to be effectively solved. Accordingly, we designed carbon quantum dots (CDs) anchored MnO 2 nanowires as heterostructure (MnO...
