چکیده

Flexible films based on novel Te-SnO2 nanocomposites were fabricated for detection of toxic gases at room temperature. The obtained via solvohermal recrystallization pure crystalline tellurium in nitric acid the presence tin chloride. energy-dispersive X-ray spectroscopy (EDX) and XRD analyses have shown that consists fluffy structures tiny agglomerates nanodimensional irregular blocks hexagonal Te polycrystalline SnO2. Both current / voltage transient characteristics flexible investigated temperature ambiance comprising different gases. maximum selectivity was revealed toward NO2, which dynamic range 0.5 – 5.0 ppm response recovery times are about 30 s 150 respectively. Analysis kinetics meets Langmuir theory adsorption. This study a simple route fabrication printable can be used electronics, inclusive development compostable gas sensors, operating

Fully inkjet printed SnO2 gas sensor on plastic substrate

A tin dioxide (SnO2) sensor was fabricated by inkjet printing onto polyimide foil. Gold electrodes and heater were printed on each side of the substrate. A SnO2 based ink was developed by sol-gel method and jetted onto the electrodes. A final annealing at 400°C compatible with the polymeric transducers allowed to synthetize the SnO2 sensing film. Electrical measurements were carried out to char...

Fabrication of Sno2/Reduced Graphene Oxide Nanocomposite Films for Sensing No2 Gas at Room-Temperature

One-pot polyol process was combined with metal organic decomposition (MOD) method to fabricate a room-temperature NO2 gas sensor based on tin dioxide and reduced graphene oxide (SO2/RGO) nanocomposite films. X-ray diffractometry (XRD) and scanning electron microscopy (SEM) were used to analyze the structure and morphology of the fabricated films. The electrical and NO2 gas-sensing properties of...

A Novel Flexible Room Temperature Ethanol Gas Sensor Based on SnO2 Doped Poly-Diallyldimethylammonium Chloride

A novel flexible room temperature ethanol gas sensor was fabricated and demonstrated in this paper. The polyimide (PI) substrate-based sensor was formed by depositing a mixture of SnO2 nanopowder and poly-diallyldimethylammonium chloride (PDDAC) on as-patterned interdigitated electrodes. PDDAC acted both as the binder, promoting the adhesion between SnO2 and the flexible PI substrate, and the d...

Sensitive and Selective Ammonia Gas Sensor Based on Molecularly Modified SnO2 †

The development of selective and cheap metal oxide gas sensor at ambient temperature is still a challenging idea. In this study, SnO2 surface functionalization was performed in order to obtain sensitive and selective gas sensor operated at ambient temperature. 3-aminopropyltriethoxysilane (APTES) was used as an intermediate step, followed by functionalization with molecules having acyl chloride...
