In this work, CSnO2 coreshell nanostructure was constructed by using one-step hydrothermal method. However, its application is often hampered by the severe volume expansion during lithiation and delithiation process, causing a lower capacity retention rate.
More importantly, the SnO2ZnOPt NS sensing materials were synthesized in situ on microelectromechanical system (MEMS) devices, which are expected to be high. Tin oxide is one of the most promising anode materials for lithium-ion batteries (LIBs) due to its high capacity and easy availability. Under these conditions, even commercial sensors (Figaro TGS 2442, Applied Sensor MLC, E2V MICS 5521) are outperformed. Pt nanoparticle (NP)-modified SnO2ZnO (SnO2ZnOPt) coreshell nanosheets (NSs) for hydrogen sulfide (H2S) gas sensing were successfully synthesized via atomic layer deposition, hydrothermal method, and magnetron sputtering. Extraordinarily high sensor signals are observed when exposing the 2 nanocomposite to CO in humid air. Especially, the 2 nanocomposite is unique and shows a fast response time (τ 90 < 30 s) and a very good response at low temperature (<250 ☌), especially under humid-air conditions. The SiO 2 Ag core-shell particles were prepared by coated with silver nanoparticles (AgNPs) on the surface of SiO 2 using dopamine oxidation self-polymerization and electroless plating process. As SMOX-based sensors (SMOX: semiconducting metal oxide), both nanocomposites show a very good sensor performance for the detection of CO and H 2.

Although similar by first sight, 2 and SnO are significantly different in view of their structure with Pd inside or outside the SnO 2 shell and in view of their sensor performance. 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.

More importantly, the SnO 2 ZnOPt NS sensing materials were synthesized in situ on microelectromechanical system (MEMS) devices, which are expected to be high-performance gas sensors with superior sensitivity, great selectivity, good.
Both nanocomposites exhibit high-surface, porous matrices of SnO 2 shells (>150 m 2 g −1) with very small SnO 2 crystallites (<10 nm) and palladium (Pd) nanoparticles (<10 nm) that are uniformly distributed in the porous SnO 2 matrix.

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(+). Pt nanoparticle (NP)-modified SnO 2 ZnO (SnO 2 ZnOPt) coreshell nanosheets (NSs) for hydrogen sulfide (H 2 S) gas sensing were successfully synthesized via atomic layer deposition, hydrothermal method, and magnetron sputtering. 2 and SnO nanocomposites are prepared via a microemulsion approach.
