Ag-modified In2O3/ZnO bundles with micro/nano porous structures have been designed and synthesized with by hydrothermal method continuing with dehydration process. Each bundle consists of nanoparticles, where nanogaps of 10-30 nm are present between the nanoparticles, leading to a porous structure. This porous structure brings high surface area and fast gas diffusion, enhancing the gas sensitiv...

The structures in amorphous (a-) Zn, Sn co-doped In2O3 (ZITO) thin films grown by pulsed laser deposition on glass under varying oxygen pressure or with varying Sn:Zn ratios were determined using X-ray absorption spectroscopy and anomalous X-ray scattering. Typical structures around cations in a-ZITO films are described and compared with crystalline (c-) ZITO films. The results show that the Zn...

Lithium (Li)-assisted indium oxide (In2O3) thin films with ordered structures were prepared on solution-processed zirconium oxide (ZrO2) gate dielectrics by spin-casting and thermally annealing hydrated indium nitrate solutions with different Li nitrate loadings. It was found that the Li-assisted In precursor films on ZrO2 dielectrics could form crystalline structures even at processing tempera...

Wide band-gap semiconductors doped with luminescent rare earth elements (REEs) have attracted recent interest due to their unique optical properties. Here we report on the synthesis of the transparent conducting oxides (TCOs) indium oxide and indium tin oxide (ITO) doped with neodymium, europium and terbium. The solid solubility in the systems was investigated and isothermal phase diagrams at 1...

Using photocatalytic hydrogen evolution (PHE) technology is a powerful way to solve the energy shortage. In this study, hexagonal hollow tubular nitrogen-doped carbon (N−C)-coated In2O3/CdZnS heterojunction photocatalyst was in situ synthesized using simple oil bath heating method. Results show that PHE rate of N−C/In2O3/CdZnS (∼22.87 µmol h−1) ∼2.4 times pristine CdZnS (∼9.49 and ∼54.5 In2O3 (...

Recent advances have enabled the demonstration of record high-performance atomically thin n-type indium oxide (In2O3) field-effect transistors with low thermal budget suitable for back-end-of-line logic or memory applications. By using ultra-thin layers In2O3, its degenerate carrier density is suppressed so that it can be modulated by conventional dielectric gating. These devices high on-curren...

Multi-field coupling, especially photo-assisted electrocatalysis, has recently been studied to further improve the oxygen evolution reaction (OER). In this study, an n-type cubic In2O3 semiconductor is employed for first time load IrOx species (Ir-In2O3 mass ratio: 17.6 %). Consequently, IrOx@In2O3 heterojunction, which exhibits outstanding OER performance promoted by weak-light irradiation, fo...

Carbon dioxide can be utilized as a feedstock to produce chemicals and renewable fuels sustainably. CO2 hydrogenation hydrocarbons through methanol mediated pathway requires more detailed study, examining interactions between reaction processes leading different product selectivities. In this particular work, we propose kinetic model for the direct hydrocarbon products over an In2O3/HZSM-5 bifu...

A plethora of metal promoters have been applied to enhance the performance In2O3 in CO2 hydrogenation methanol, a prospective energy carrier. However, lack systematic catalyst preparation and evaluation precludes direct comparison their speciation promotional effects, consequently, design an optimal system. Herein, flame spray pyrolysis (FSP) is employed as standardized synthesis method introdu...
