An ultrasensitive NO<sub>2</sub> sensing material was fabricated using ultrafine SnO<sub>2</sub> nanoparticle-modified hierarchical SnS<sub>2</sub> nanoflowers.
An effective long-term nitrogen dioxide (NO2) monitoring at trace concentration is critical for protecting the ecological environment and public health. Tellurium (Te), as a recently discovered 2D elemental material, promising NO2 detection because of its suitable band structure gas adsorption charge mobility. However, high activity Te leads to poor stability in ambient harsh conditions, limiting application gas-sensitive material. Herein, single-elemental Te@Se heterostructures with...
The unique features of SnS2 make it a sensitive material ideal for preparing high-performance nitrogen dioxide (NO2) gas sensors. However, sensors based on pristine tin disulfide (SnS2) fail to work at room temperature (RT) owing their poor intrinsic conductivity and weak adsorptivity toward the target gas, thereby impeding wide application. Herein, an ultrasensitive fully recoverable room-temperature NO2 sensor SnS2/SnS p-n heterojunctions with accumulation layer was fabricated. amounts can...
Tin disulfide (SnS2) has been extensively researched as a promising sensing material due to its large electronegativity, suitable band gap, earth abundance, and nontoxicity. However, the poor conductivity slow response/recovery speed at room temperature greatly hinder application in high-performance practical gas sensors. Herein, promote study of SnS2-based sensors, hierarchical SnS2/TiO2 heterostructure was synthesized used detect NO2 with help light illumination. Through synergistic effect...
One-dimensional hierarchical Bi2WO6 hollow tubes with porous walls have been solvothermally synthesized using Bi2O3 rods as both template and reactant, characterized by FESEM, TEM XRD. Experimental results indicate that the of these micro-tubes are made nanoplates stacking in a disordered state, which creates an interesting macro-mesoporous structure. Influencing factors on resulting products including adding order reactants, ethanol content, pH value systematically investigated. A possible...

Vacancy defects are intrinsically present in the as-grown MoSe 2 , which may greatly affect its gas sensing performance.
Heterojunction engineering plays an indispensable role in improving gas-sensing performance. However, rational heterojunction to achieve room-temperature NO
Carbon-doping mediated synergistic effect of energy-band modification and vacancy provides a new solution for developing high-performance LMDs-based gas sensors.
Nanosheet-assembled hierarchical SnSe 2 could serve as a new suitable candidate for high-performance room-temperature NO gas sensing.
Abstract Controllable interfacial strain can manipulate the physical properties of epitaxial films and help understand nature correlation between atomic microstructures. By using a proper design vicinal single-crystal substrate, interface in thin be well controlled by adjusting miscut angle via surface-step-terrace matching growth mode. Here, we demonstrate that LaAlO 3 (LAO) substrates with various angles 1.0°, 2.75°, 5.0° were used to tune dielectric CaCu Ti 4 O 12 (CCTO) films. A model...

Although photodegradation is the most widely studied method for purification of water, challenges post‐separation catalysts from water make technique unsuitable practical applications. In this study, separation‐free TiO 2 /reduced graphene oxide (rGO) multilayer films were first prepared through layer‐by‐layer (LbL) assembly and (GO) on quartz slides, followed by a reduction assembled GO to rGO. For proof‐of‐concept demonstration novel continuous photocatalysis with potential scaled‐up...
