Ag@SnO2 nanosheets were prepared through a hydrothermal method followed by heat treatment and liquid reduction process. Many Ag nanoparticles (Ag NPs) dispersed uniformly over the surface of SnO2 nanosheets. The thickness was approximately 10 nm. After decoration with NPs, nanosheet sensors exhibited improved gas-sensing behaviors compared to pure sensor. response cross-linked decorated NP for ...

High capacity, rapid-charging, and long-term recyclability are the essential characteristics of high-performance lithium-ion battery (LIB) electrodes, which particularly important in electric vehicle industry. Bimetallic Zn2SnO4 nanoparticles wrapped carbon shells were supersonically sprayed with reduced graphene oxide (rGO) nanosheets to fabricate binder-free, long-term-stable LIB anodes. The ...

We studied the structural behavior and electrical transport properties of epitaxial a-SnO thin films grown on the (1̄012) a-Al2O3 ~sapphire! substrate. Hall effect measurements revealed that the epitaxial as-deposited SnO film is a p-type semiconductor. In situ x-ray diffraction studies show that the a-SnO phase is metastable and will transform into SnO2 with the rutile type structure when annea...

Tin dioxide (SnO2) is a widely investigated lithium (Li) storage material because of its easy preparation, two-step storage mechanism and high specific capacity for lithium-ion batteries (LIBs). In this contribution, a phase-pure cobalt-doped SnO2 (Co/SnO2) and a cobalt and nitrogen co-doped SnO2 (Co-N/SnO2) nanocrystals are prepared to explore their Li storage behaviors. It is found that the m...

Tin dioxide (SnO2) represents an importantmetal-oxide group that can be suitable for a range of applications through the incorporation of dopants. For example, the electrical conductivity of intrinsic SnO2 depends strongly on the surface properties, as molecular adsorption/desorption will affect the band modulation and space-charge layer, which makes SnO2 an important conductance-type gas-sensi...

this paper reports the synthesis of polypyrrole coated sno2/znoelectrospunnanofibers via vapor phase polymerization method. in order to prepare one dimensional (sno2-zno)/polypyrrole with the core sheath structure, first sno2-zno composite nanofibers were synthesized via electrospinning method followed by adsorption of fe3+ on the surface of the sno2-zno nanofibers and finally pyrrole was polym...

The sensitivity of SnO2 nanoparticles/reduced graphene oxide hybrid to NO2 gas is discussed in the present work using density functional theory (DFT). nanoparticle shapes are taken as pyramids, proved by experiments. reduced (rGO) edges have oxygen or oxygen-containing groups. However, upper and lower surfaces rGO clean, expected from reduction procedure. Results show that particles connected a...

The chemical bath deposition (CBD) technique was used for the synthesis of the tin oxide (SnO2) thin films. X-ray diffraction (XRD) was employed to find the crystallite size by using Debye Scherrer’s formula. The surface morphology of SnO2 films was analyzed by the scanning electron microscopic (SEM) studies. The FT-IR spectrum exhibits the strong presence of SnO2. The optical properties of the...

We proposed optical gas sensors based on PLCs integrated with SnO2 thin films. SnO2 thin film was placed on the core layer appeared by removing the upper cladding layer of PLC. The propagation loss is analyzed using 2-D finite-difference time-domain method as a function of refractive index change of SnO2 thin film. The propagation loss of 0.18 dB was observed when the change of refractive index...
