Monodispersed In2O3 mesoporous nanospheres: One-step facile synthesis and the improved gas-sensing performance

Thermoelectric Properties of Zinc-Doped Indium Tin Oxide Thin Films Prepared Using the Magnetron Co-Sputtering Method

“…Figure 7 shows the FT-IR spectra of ITO:Zn thin films for varied zinc content against the wavenumbers ranging from 650 to 4000 cm −1 at room temperature (RT). The peaks at 906.56-925.31 cm −1 are related to atoms that are still unoxidized [47]. The peaks at 1023.49-1026.37 cm −1 are related to the phonon mode of the In 2 O 3 lattice [47].…”

“…The peaks at 1023.49-1026.37 cm −1 are related to the phonon mode of the In 2 O 3 lattice [47]. The OH-stretching vibration mode is related to a wavenumber around 3240 cm −1 [47][48][49][50][51][52]. It was expected that the OH-stretching vibration would increase as the zinc content in the films increased.…”

Metal‐Organic Frameworks‐Derived Porous In2O3 Hollow Nanorod for High‐Performance Ethanol Gas Sensor

“…Among the various types of gas sensors, metal oxide semiconductors (MOS) have been regarded as promising candidates for gas‐sensing materials owing to their unique advantages, such as short response time, low cost, controllable preparation, simple integration and good suitability for design of portable instruments . To date, many kinds of n‐type MOS (such as ZnO, Fe 2 O 3 , In 2 O 3 ,, SnO 2 , WO 3 , etc.) and p‐type MOS (such as CuO, NiO and Co 3 O 4 , etc.)…”

“…Nanostructured materials with small grain size, tailored morphology, and large surface‐to‐volume ratio, are quite suitable for fabricating gas sensors ,. In this regard, numerous nanostructured In 2 O 3 materials with various dimensions, morphologies and architectures have been synthesized and explored as sensing materials, including nanosphere, nanowire, nanorod, nanotube, and nanocube, etc . On the other hand, porous structure with large surface area would be favorable for the absorption of gas molecules, contributing to the improved sensing performance…”

A high performance methanol gas sensor based on palladium-platinum-In2O3 composited nanocrystalline SnO2

“…Among different sensor types, metal oxide semiconductor (MOSs) gas sensors are the most popular type as it is more practical and market-oriented. A series of promising metal oxide, such as SnO 2 , In 2 O 3 , ZnO, TiO 2 , Fe 2 O 3 [6][7][8][9][10], and so on, has been used as sensing materials of gas sensors. They can test the toxic gases of ambient atmosphere through changes in the resistance of metal oxide.…”
