Abstract
This review work reports the synthesis, the morphological, structural, spectroscopic, and electrical properties, the sensing performances of TixSn1-xO2 solid solutions, using pristine SnO2 and TiO2 as reference. Each characterization highlighted two behavioral classes for the solid solutions: SnO2-like and TiO2-like, being the oxide with x = 0.25 the borderline sample. Furthermore, two real applications of (Ti, Sn) solid solutions are described: i) in air quality monitoring to detect carbon monoxide (CO), ii) to detect the variation of analytes concentrations in samples of hydraulic fluid headspace collected during the system running.
