Abstract The study of hydrogen evolution reaction and oxygen electrocatalysts for water electrolysis is a developing field in which noble metal-based materials are commonly used. However, the associated high cost low abundance metals limit their practical application. Non-noble metal catalysts, aside from being inexpensive, highly abundant environmental friendly, can possess electrical conductivity, good structural tunability comparable electrocatalytic performances to state-of-the-art...
Brush-like hierarchical ZnO nanostructures assembled from initial 1D were prepared sequential nucleation and growth following a hydrothermal process. The morphology, structure, optical property of characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), photoluminescence (PL) studies. FE-SEM images showed that the brush-like are composed 6-fold nanorod-arrays grown on side surface core nanowires. Compared with nanowires, easily fabricated satisfactory...
This article comprehensively reviews the recent progress in development of key components lithium-ion batteries, including positive/negative electrodes, electrolytes and separators. The necessity developing batteries with high energy/power density long cycle-life is emphasized both terms industrial academic perspectives.
A novel photocatalysis and gas sensing material was synthesized by decorating Au nanoparticles on tungsten trioxide nanorods. Tungsten nanorods were prepared through the ion-exchange method combined with hydrothermal treatment further modified (Au NPs). After NPs decorated surface of WO3 (WO3 NRs), reducing (hydrogen, methanol, ethanol, etc.) properties photocatalytic performance rhodamine B (RhB) all greatly improved. NP NP@WO3 NRs) exhibit not only larger response (H2 50 ppm, recovery time...
An ordered mesoporous WO3 material with a highly crystalline framework was synthesized by using amphiphilic poly(ethylene oxide)-b-polystyrene (PEO-b-PS) diblock copolymers as structure-directing agent through solvent-evaporation-induced self-assembly method combined simple template-carbonization strategy. The obtained materials have large uniform mesopore size (ca. 10.9 nm) and high surface area 121 m(2) g(-1)). WO3-based H2S gas sensor shows an excellent performance for sensing at low...
In this study, a facile one-pot process for the synthesis of hierarchical VS2/graphene nanosheets (VS2/GNS) composites based on coincident interaction VS2 and reduced graphene oxide (rGO) sheets in presence cetyltrimethylammonium bromide is developed first time. The nanocomposites possess structure 50 nm thickness homogeneously anchored graphene. VS2/GNS exhibit an impressive high-rate capability good cyclic stability as cathode material Li-ion batteries, which retain 89.3% initial capacity...
Abstract Hierarchical SnO 2 nanoflowers, assembled from single‐crystalline nanosheets with high‐index (11 $ \bar 3 ) and (10 facets exposed, are prepared via a hydrothermal method using sodium fluoride as the morphology controlling agent. Formation of 3D hierarchical architecture comprising takes place Ostwald ripening mechanism, growth orientation regulated by adsorbate fluorine species. The use Sn(II) precursor results in simultaneous Sn 2+ self‐doping nanoflowers tunable oxygen vacancy...
Two-dimensional (2D) nanomaterials show great potential for electrocatalysis or other applications that require large surface area.
Bimetallic nanoparticles (NPs) usually exhibit some novel properties due to the synergistic effects of two distinct metals, which is expected play an important role in field gas sensing. PdPt bimetal NPs with Pd-rich shell and Pt-rich core were successfully synthesized used modify SnO2 nanosheets. The 1P-PdPt/SnO2-A sensor obtained by self-assemblies exhibited temperature-dependent dual selectivity CO at 100 °C CH4 320 °C. Furthermore, possessed good long term stability antihumidity...
Abstract Reasonably constructing an atomic interface is pronouncedly essential for surface-related gas-sensing reaction. Herein, we present ingenious feedback-regulation system by changing the interactional mode between single Pt atoms and adjacent S species high-efficiency SO 2 sensing. We found that sites on MoS surface can induce easier volatilization of to activate whole inert plane. Reversely, activated provide a feedback role in tailoring antibonding-orbital electronic occupancy state...
Square-shaped single-crystalline SnO(2) nanowires and their sphere-like hierarchical structures were synthesized successfully with a template-free hydrothermal approach. It was found that an intermediate phase-Na(2)Sn(OH)(6)-is first produced because it is slow to dissolve in ethanol/water media. The phase gradually decomposes converts into at temperatures higher than 200 °C. reaction temperature also affects the microstructure of nanomaterials. Uniform square-shaped nanowires, which form...
