A new type of vanadium sulfide (V<sub>2</sub>S<sub>3</sub>) was used for high-performance lithium–sulfur batteries.
Core–shell heterojunction nanostructure-based sensors often suffer from the blocking effect shell layer. Here, a type of sandwich-structured hollow nanofiber In2S3/In2O3/In2S3 (ISOS HNF) was designed via an electrospinning technique combining with postvulcanization treatments. The resultant ISOS HNF possesses double In2S3/In2O3 heterointerfaces at both sides In2O3 tube walls, which highly enhance junction on electron transport during gas-sensing processes. Also, two In2S3 coatings are...
Perovskites exhibit catalytic properties on the oxygen evolution reaction (OER) in water electrolysis. Elemental doping by specific preparation methods is a good strategy to obtain highly catalytical active perovskite catalysts. In this work, La0.5Sr0.5Co1−xNixO3−δ materials doped with different ratios of nickel were successfully synthesized sol-gel method. The electrochemical measurement results show that for OER 1 M KOH solution, La0.5Sr0.5Co0.8Ni0.2O3−δ prepared method requires only low...
Pt catalysts are investigated for methanol oxidation in direct fuel cells, utilizing the electrochemical quartz microbalance method (EQCM) with exceptional resolution and sensitivity. were deposited onto gas-diffusion layer of carbon using stationary potential electrodeposition. Physical characterization tests performed. SEM results showed that presented dendrite crystals nanoscale facets. Cyclic voltammetry (CV) demonstrated current density reaction highly reached 1020 mA·cm−2 catalyst by...
It is demonstrated that the incorporation of graphene materials into oxide-based photoanodes can greatly increase photoelectrochemical devices' performances. In this work, reduced oxide (rGO) has been incorporated P25-TiO2 nanoparticle (NP) based for fiber-shaped dye-sensitized solar cells (FDSSCs). Results showed rGO nanosheets have uniformly dispersed within P25 nanopanicle layers, and, as expected, increased FDSSCs' short current density from 8.344 to 12.935 mA cm(-2), open circuit...
Ordered array structures will greatly reduce the stress formation in wearable electric devices during dynamic bending operation. In this work, highly flexible TiN-based fiber counter electrodes (FCEs) were designed via a post-ammonization treatment on hydrothermally grown TiO2 nanowire arrays. Results show that obtained TiN nanorod arrays (NRAs) are well aligned with diameter of 200–320 nm and length several hundred nanometers to ∼1 μm. Moreover, fiber-shaped dye-sensitized solar cells...
Active metal ions often show a strong cutting effect on the chemical bonds during high-temperature thermal processes. Herein, one-pot ion cutting-assisted method was adopted to design defect-rich MoS2-x nanosheet (NS)/ZnS nanoparticle (NP) heterojunction composites carbon nanofiber skeletons (CNF@MoS2-x/ZnS) via simple Ar-ambience annealing. Results that Zn2+ capture S2- from MoS2 and form into ZnS NPs, NSs lose become ones. As sulfur hosts for lithium-sulfur batteries (LSBs),...
