Such high sensitivity was believed to be controlled by the nanoscale SnO 2 layer, which was determined from pinch-off and fully conductive state. It is a condition of access that users recognise and abide by the legal requirements associated with these rights. It was found that the ZnO-SnO 2 core-shell nanowires exhibited excellent hydrogen sensor performance, such as the sensitivity is up to 89 against 200 ppm hydrogen.

In sequence, ZnO shell layers were deposited using atomic layer deposition on the electrospinning synthesized SnO2 nanofibers. Coreshell-structured SnO 2 C microspheres have been synthesized through a one-pot rapid microwave hydrothermal treatment, which is a template-free method with environment-friendly and inexpensive starting materials. 10 nm composed of mainly graphitic carbon. 40 nm containing iron species and a shell thickness of ca. The synthesized CNSFe catalyst exhibited a coreshell structure with a core of ca. These preliminary results strongly suggest the great potential of this novel electron transfer material in high-efficiency perovskite solar cells. We synthesized a unique carbon nanosphere (CNS)-encapsulated Fe coreshell catalyst (CNSFe) for CO2 hydrogenation. The reversible capacity of SnO(2)/WO(3) core-shell nanorods is 845.9 mA. WO(3) nanorods are uniformly coated with SnO(2) nanoparticles via a facile wet-chemical route. To our knowledge, this strategy may be the rst report on heterogeneous branched coreshell SnO 2-PANI nanorod arrays. The results open a way for enhancing the reversible capacity of alloy-type metal oxide anode materials with a novel mechanism by which nanostructured metallic tungsten makes extra Li(2)O (from SnO(2)) reversibly convert to Li(+).
Thus, enhanced rate capability and cyclability of heterogeneous branched coreshell SnO 2PANI nanorod arrays can be anticipated. Meanwhile, the uniform core-shell ZnOSnO 2 nanoparticles is extremely favorable to the growth of inorganic perovskite films. 2 nanorod core by the PANI shell, ensuring the excellent structure stability. First, SnO2 nanofibers were synthesized by electrospinning. The core-shell ZnOSnO 2 nanoparticles size is 8.1 nm with the SnO 2 shell thickness of 3.4 nm, and the electron mobility is seven times more than SnO 2 nanoparticles.
