A new class of Co9 S8 @MoS2 core-shell structures formed on carbon nanofibers composed cubic as cores and layered MoS2 shells is described. The design these nanostructures allows the advantages to be combined, serving a bifunctional electrocatalyst for H2 O2 evolution.
Abstract Tuning surface strain is a new strategy for boosting catalytic activity to achieve sustainable energy supplies; however, correlating the with performance scarce because such mechanistic studies strongly require capability of tailoring on catalysts as precisely possible. Herein, conceptual tuning tensile Co 9 S 8 /MoS 2 core/shell nanocrystals hydrogen evolution reaction (HER) by controlling MoS shell numbers demonstrated. It found that can be tuned from 3.5% 0% changing layer 5L 1L,...
A self-assembled three-dimensional hierarchical porous V<sub>2</sub>O<sub>5</sub>/graphene hybrid aerogel for high-performance supercapacitor was synthesized.
Abstract Highly stretchable porous materials are promising for flexible electronics but their fabrication is a great challenge. Herein, several kinds of highly conductive elastomers with low or negative Poisson’s ratios achieved by uniaxial, biaxial, and triaxial hot-pressing strategies. The reduced graphene oxide/polymer nanocomposite folded structures obtained uniaxial hot pressing exhibit high stretchability up to 1200% strain. Furthermore, the meta-elastomers reentrant combining biaxial...
While high-entropy alloy (HEA) catalysts seem to have the potential break linear scaling relationships (LSRs) due their structural complexity, weighted averaging of properties among multiple principal components actually makes it challenging diverge from symmetry dependencies imposed by LSRs. Herein, we develop a 'surface entropy reduction' method induce exsolution component with weak affinity for others, resulting in formation few-atom-layer metal (FL-M) on surface HEAs. These exsolved FL-M...
Abstract The manipulation of surface catalytic sites has rarely been explored for metal borides, and the subsurface effects on electrocatalytic activity nitrogen reduction reaction (NRR) remain unknown.

Designing macroscopic, 3D porous multifunctional materials is of great importance in many fields, including energy storage, thermal insulation, sensors, and catalysis. Polar bears have hairs with a membrane-pore structure, which contributes to adaptation harsh environments. Inspired by polar bear hair, this study reports facile route fabricate silica nanotube aerogels (SNTAs) via chemical vapor deposition (CVD) onto the sacrificial carbon nanoskeleton aerogel (CA). The resulting SNTAs are...
Hollow nanostructures are attractive for energy storage and conversion, drug delivery, catalysis applications. Although these hollow of compounds can be generated through the processes involving well-established Kirkendall effect or ion exchange method, a similar process synthesis pure-substance one (e.g., Si) remains elusive. Inspired by above two methods, we introduce continuous ultrathin carbon layer on silica nano/microstructures (Stöber spheres, diatom frustules, sphere in sphere) as...
Electrode materials of flexible asymmetric supercapacitors are usually suffers from low capacitance and sluggish kinetics.

A local electric field is induced to engineer the interface of vanadium pentoxide nanofibers (V2 O5 -NF) manipulate charge transport behavior and obtain high-energy durable supercapacitors. The V2 -NF modified with oxygen vacancies (Vö) in a one-step polymerization process polyaniline (PANI). In storage process, deriving from lopsided distribution around Vö will provide Coulombic forces promote resultant Vö-V2 /PANI nanocable electrode. Furthermore, an ≈7 nm porous PANI coating serves as...

As one of the most promising candidates for supercapacitor electrodes, vanadium pentoxide (V<sub>2</sub>O<sub>5</sub>) usually suffers from poor electronic conductivity and small ionic diffusivity.
Multiwalled carbon nanotubes (MWCNTs)–V2O5 integrated composite with nanosized architecture has been synthesized through hydrothermal treatment combined a post-sintering process. During the reaction, protonated hexadecylamine (C16H33NH3+) acts as an intermediator, which links negatively charged vanadium oxide layer mixed-acid pretreated MWCNTs by weak electrostatic forces to form three-phase hybrid (MWCNTs–C16–VOx). MWCNT–V2O5 and V2O5 nanoparticles can be obtained sintering MWCNTs–C16–VOx...
V2O5/poly(3,4-ethylenedioxythiophene) nanocables with oxygen vacancies gradually decreasing from the surface to core (G-V2O5/PEDOT nanocables) were prepared as electrodes for supercapacitors. Gradient formed when 3,4-ethylenedioxythiophene monomers polymerized conformally on of V2O5 nanofibers, providing G-V2O5/PEDOT much improved charge storage kinetics and structural durability. The role gradient in enhancing transfer/transport was also evidenced by means density functional theory...
