摘要

In this paper, we describe how to synthesize Ag-doped In2O3 nano particles and fabricate highly sensitive and selective alcohol sensors by solid-state reaction treatment from In(NO3)(3)center dot 5H(2)O and AgNO3 mixtures at room temperature followed by calcination at 600 degrees C for 2 h. The samples were characterized by X-ray diffraction, scanning electronic microscopy, X-ray photoelectron spectroscopy. The diameter of the as-synthesized particle diameter is similar to 80 nm under different dosage of Ag doping. In comparison with pure In2O3 sensor, all of the Ag-doped sensors showed better sensing performance in sensitivity, selectivity and optimum operating temperature. The effects of Ag content, alcohol vapor concentration, and operating temperature on the sensing characteristics of the Ag-doped In2O3 sensors were also investigated. We found that the Ag-doped sensor containing 10.0 mol % Ag exhibited the maximum sensitivity to alcohol vapor at 150 degrees C. A possible mechanism for the influence of Ag on the alcohol-sensing properties of Ag-doped In2O3 sensors was proposed.

Summary: In this study, In2O3/PANI composites were synthesized using the hydrothermal technique to explore their sensing capabilities for NO2 gas. The gas sensing properties, such as response/recovery time, optimal temperature, and recyclability, were investigated by analyzing the morphology, purity, and crystal structures of the samples. The In2O3/PANI-1 sensors exhibited high responses, quick response and recovery times, and a low detection limit to NO2 gas at a working temperature of 250 degrees C. The fundamental detecting mechanism for NO2 gas and the electrical characteristics of the In2O3/PANI composites were also discussed.

Nanosheet-assembled In2O3 for sensitive and selective ozone detection at low temperature

Ning Sui, Peng Zhang, Shuang Cao, Tingting Zhou, Tong Zhang

Summary: A series of nanosheet-assembled In2O3 materials with different chemisorbed oxygen components were successfully prepared, showing enhanced response by adjusting the amount of chemisorbed oxygen. As an efficient O-3 detector, the sensor exhibited outstanding response to low concentrations of O-3 and a low LOD at a relatively low operating temperature. The O-3 sensing behaviors were interfered by background oxygen, suggesting competitive adsorption between O-3 and O-2 molecules.
