A new transparent conducting oxide ~TCO!, which can be expressed as Ga32xIn51xSn2O16; 0.2 <x<1.6, has been identified. The equilibrium phase relationships of this new material with respect to three other TCOs in Ga2O3–In2O3–SnO2 are reported. The optical properties of this phase are slightly superior to Sn-doped indium oxide ~ITO! and depend on composition. A room-temperature conductivity of 37...

Helical inorganic nanostructures have received great attention due to their unique structures that could be interesting for both fundamental research and nanodevice applications. Using a tube-in-tube laser ablation chemical vapor deposition (CVD) method with gold nanoparticles as the catalysts, we reported the synthesis of self-assembled kinked In2O3 nanospirals and multikinked nanowires. As-sy...

This study investigates the preparation of InSb-added TiO2 nanocomposite films by RF sputtering. The optical absorption spectra are obviously shifted to visible and near-infrared regions. High-resolution transmission electron microscopy indicates that sphere-shaped InSb nanocrystals with a size of about 15 nm are dispersed in a matrix. The X-ray diffraction result reveals that the matrix forms ...

Acetone detection is of great significance for environmental monitoring or diagnosis diabetes. Nevertheless, fast and sensitive acetone at low temperatures remains challenging. Herein, a series rGO-functionalized three-dimensional (3D) In2O3 flower-like structures were designed synthesized via facile hydrothermal method, their acetone-sensing properties systematically investigated. Compared to ...

Pd-In2O3 catalysts are among the most promising alternatives to Cu-ZnO-Al2O3 for synthesis of CH3OH from CO2. However, intrinsic activity and stability In2O3 per unit mass should be increased reduce content this scarcely available element enhance catalyst lifetime. Herein, we propose demonstrate a strategy obtaining highly dispersed Pd nanoparticles onto an Al2O3 matrix by one-step coprecipitat...

A simple and rapid method for the growth of an In2O3 shell on colloidal InP nanocrystals is described, increasing their fluorescence efficiency by one order of magnitude.

In2O3-x thin films with a thickness of 100-990 nm were grown by dc magnetron sputtering. Their structural, electrical and ozone sensing properties were analyzed. Structural investigations carried out by electron probe micro analysis, secondary ion mass spectrometry and atomic force microscopy showed a strong correlation between stoichiometry, surface topology and gas sensitivity. Moreover, the ...

In this communication, we report a successful synthesis of quasi-monodisperse In2O3 nanocrystals with high crystallinity in a high-temperature organic solution. The average size of nanocrystals can be tuned using a dynamic injection technique. TEM and XRD investigations indicate that each nanocrystal is a single crystal. The optical determination implies that the photoluminescence behavior of t...

Bulk and surface sensitive x-ray spectroscopic techniques are applied in tandem to show that the valence band edge for In2O3 is found significantly closer to the bottom of the conduction band than expected on the basis of the widely quoted bulk band gap of 3.75 eV. First-principles theory shows that the upper valence bands of In2O3 exhibit a small dispersion and the conduction band minimum is p...

Methanol synthesis via catalytic CO2 hydrogenation is an important reaction where a valuable fuel and chemical produced from greenhouse gas. In2O3- Pd-promoted In2O3 have experimentally shown promising activity selectivity, although the nature of active sites remains under debate. In this study, kinetic behavior potential in toward methanol competing reverse water–gas shift assessed by explorin...
