We have designed a new ternary structure to enhance the sensing properties of WS2 nanosheet (NS)-based gas sensors at room temperature (RT) in self-heating mode. SnO2 nanowires (NWs, 10–30 wt%) were added NSs and then Au nanoparticles (NPs) deposited on surface resulting composites by UV irradiation. The Au-decorated 10 wt% SnO2–WS2 composition showed highest properties. presence NWs effectivel...

1-D nanostructures, such as nanowires and nanotubes, have been extensively studied due to their potentials as building blocks for fabricating electronic, magnetic, electrooptic, and electrochemical nanodevices. Especially, wide-bandgap semiconductor nanowires and nanorods including ZnO and SnO2 were reported significantly. As for their synthetic routes, a carbothermal reduction process has been...

Tin oxide (SnO2) hollow spheres modified with titanium dioxide (TiO2) nanowires (NWs) synthesized by sequential hydrothermal reactions were investigated as photoanodes for dye-sensitized solar cells. Not only does the hydrothermal treatment form numerous short TiO2 NWs on the surface of SnO2 spheres, but also passivates the surface of SnO2. Consequently, the specific surface area of the photoan...

The as-synthesized nanowires and nanobelts usually have a large size distribution. We demonstrate here a ball milling technique for narrowing the size distribution of oxide nanobelts and nanowires. High-resolution scanning and transmission electron microscopy reveals that the one-dimensional SnO2 nanostructures with size .150 nm are sensitive to the milling effect and most of them were fracture...

Smart chemical sensor based on CMOS(complementary metal-oxide-semiconductor) compatible SOI(silicon on insulator) microheater platform was realized by facilitating ZnO nanowires growth on the small membrane at the relatively low temperature. Our SOI microheater platform can be operated at the very low power consumption with novel metal oxide sensing materials, like ZnO or SnO2 nanostructured ma...

In the last few years nanostructure ZnO is being intensively investigated from the growth control, structural and physical characterization, to device performance. There are now increasing interests in a wide range of ZnO-based ternary compound nanostructures offering even larger possibilities. These compounds can be useful as multi-color light-emitting device, sensors, transparent electrodes, ...

Functional 1D metal oxides have attracted much attention because of their unique applications in electronic, optoelectronic, and spintronic devices. For semiconducting oxide nanowires (NWs) (e.g., ZnO, In2O3, and SnO2 NWs), field-effect transistors and light-emitting diodes have been demonstrated. Metallic oxide nanoscale materials, such as nanoscale RuO2, can be good candidates as interconnect...

One-dimensional nanostructures such as nanowires, nanobelts, and nanotubes have attracted much attention as a result of their unique properties, which can be applied in the fabrication of biomedical sensors, optoelectronic devices, field-effect transistors, and field-emission devices, for example. In particular, one-dimensional nanostructures of metal oxides such as ZnO, SnO2, [3] a-Fe2O3, [4] ...
