In this work, hierarchical WO3 core-shell microspheres were synthesized via a facile template-free precipitation method. Gas sensing properties of the synthesized powder to acetone and some other volatile organic compounds were comparatively investigated with commercial WO3 nanoparticles. The synthesized and commercial powders were characterized by X-ray diffraction, scanning electron microscopy, particle size distribution analysis, Brunauer–Emmett–Teller […]
Phosphorene nanoribbon (PNR) is a two-dimensional crystalline substance possessing semiconductor property, which makes it a new promising gas sensor. The gas sensing performance significantly depends on the adsorption mechanism and the strength of bonding between gas molecules and phosphorene atoms. Adsorption of a gas molecule onto PNR can be investigated through different parameters, such as […]
