Development and application of micromachined Pd/SnO2 gas sensors with zeolite coatings

Zeolite Thin Films and Membranes: From Fundamental to Applications

“…These molecular fi lters decreased interference of undesired molecules mainly via a selective adsorption mechanism that hindered the diffusion of less strongly adsorbed species. In a subsequent work [ 227 ], the system was scaled down by a factor of 50, and a microdropping procedure was used to deposit the zeolite barrier. The micromachined sensor presented a considerable reduction of response times without apparent loss of performance.…”

The Relationship Between the Synthesis and Morphology of SnO2-Ag2O Nanocomposite

“…The obtained precipitation was centrifuged, washed with distilled water until to complete the omission of the chloride ions, and after that the precipitation is solved in nitric acid solution completely. In this step, 0.6 mmol silver nitrate (AgNO 3 to the stirred solution again until to reach pH 8. Finally, it is dried at 110 • C for 2 h. Eventually, the precipitation powder is annealed at various temperatures.…”

“…Tin dioxide (SnO 2) semiconductors have been intensely studied over the past decades, due to a wide range of applications, such as gas sensor in SnO 2 nanocrystal, [1] C 2 H 2 gas sensor, [2] Pd/SnO 2 gas sensor, [3] CO and CH 4 dual selectivity, [4] SnO 2 based gas sensor, [5] Pt/SnO 2 gas sensor, [6] SnO2 nanorod based gas sensors, [7] nanospherical based gas sensors, [8] and so on.…”

Study of structural, electrical and photoconductive properties of F and P co-doped SnO2 transparent semiconducting thin film deposited by spray pyrolysis

“…The wide and direct band gap semiconductor materials are of much interest for blue and optical detector devices in UV region, such as light-emitting diodes (LED) and laser diodes [1]. As wide band gap semiconductors, Transparent conducting oxides (TCO's) such as SnO 2 and doped SnO 2 are known to have a wide range of technological applications, such as transparent conducting electrodes, dye-sensitized solar cells [2,3] and chemical sensors [4,5], and now they seem to be more attractive for their luminescence properties [6][7][8].…”
