Preparation of reliable, stable, and highly responsive gas-sensing devices for the detection acetone has been considered to be a key issue development accurate disease diagnosis systems via exhaled breath. In this paper, novel CeO2 nanodot-decorated WO3 nanowires are successfully synthesized through sequential hydrothermal thermolysis process. Such exhibited remarkable enhancement in acetone-sensing performance based on miniaturized micro-electromechanical system device, which affords high...
Photonic nanostructures that realize ultrafast switching of light polarization are essential to advancements in the area optical information processing. The unprecedented flexibility metasurfaces manipulation makes them a promising candidate for active control. However, due lack materials exhibiting fast as well large refractive index change, photonic metadevices capable remain elusive. Here, an ultrathin nonlinear chiral meta-mirror consisting array amorphous silicon (α-Si) split-ring...
MOF-5-like crystals were studied by small-angle X-ray scattering (SAXS) to reveal, both quantitatively and qualitatively, their real structural details, including pore surface characteristics, shape, size distribution, specific area (SSA), spatial pore−network structure. A combined SAXS wide-angle (WAXS) experiment was conducted investigate the variation of structure with MOF-5 crystalline phase produced at different cooling rates. The SSA synthesized herein spanned a broad range from ∼3100...
The metal-organic frameworks (MOF) with low and medium specific surface areas (SSA) were shown to be able adsorb hydrogen via bridged spillover at room temperature (RT) up an amount of full coverage in the MOF. Anomalous small-angle X-ray scattering was employed investigate key relationship between structures storage properties involved materials. It found that tunable imperfect lattice defects 3D pore network MOF crystal are most critical for RT uptake rather than known micropores crystal,...
There are two regimes that exhibit distinctive behaviors of spillover. The present study used small-angle X-ray scattering (SAXS) to measure size distribution Pt nanoparticles in the bulk Pt-impregnated active carbon sample. peak position as determined by SAXS turns out be at ∼1 nm, which is rarely discussed this field. technique complementary other characterization methods. experimental clue coming from measurement and our hydrogen storage capacity shows impregnated nm can enhance spillover...
The principal obstacle to the implementation of a hydrogen-based economy remains storage under ambient conditions temperature and pressure. While most approaches this problem have date focused on physisorption, wherein useful uptake is realized only at low temperatures (e.g., 77 K), recent experiments suggested possibility chemisorptive strategies based hydrogen spillover. We report results an experimental theoretical investigation into thermochemistry dihydrogen chemisorption catalytically...
A nanoporous and large surface area (∼800 m2/g) graphene-based material was produced by plasma treatment of natural flake graphite subsequently decorated with platinum (Pt) nano-sized particles via thermal reduction a Pt precursor (chloroplatinic acid). The carbon-metal nanocomposite showed ∼2 wt% loading well-dispersed nanoparticles (<2 nm) across its porous graphene surface, while neither significant chemistry alteration nor pore structure degradation observed due to the decoration...
In order to improve room-temperature hydrogen storage, platinum (Pt) nanoparticles (NPs) are doped onto the Zr-terephthalate metal–organic framework (MOF) UiO-66 and its derivatives for H2 adsorption via spillover effect under a high-pressure environment. Different MOF synthetic modulators applied nanoparticle size manipulation, surface functionality is designed Pt dispersion. Powder X-ray diffraction shows retained integrity after decoration, broad peak indicates well-dispersed NPs. The...
Hydrogen released from chemical hydride ammonia borane (AB, NH3BH3) can be greatly improved when AB is confined in metal–organic frameworks (MOFs), showing reduced decomposition temperature and suppressed unwanted byproducts. However, it still debatable whether the mechanism of dehydrogenation due to catalysis or nanosize. In this research, selected MOFs (IRMOF-1, IRMOF-10, UiO-66, UiO-67, MIL-53(Al)) were chosen explore both catalytic effect metal clusters manipulation pore size for...

Abstract Stable solid electrolyte interface (SEI) is the key to improve electrochemical performance of lithium metal batteries (LMBs). However, there are still many puzzles about SEI film that have not been well explained, due complexity reactions involving in formation and absence direct observation methods for SEI. Here, this work realizes by skillfully designed fluorescent tracers acting as an film‐forming additive electrolytes. These three important moieties: olefin group polymerization...
