Ozone detection in the ppt-level with rGO-ZnO based sensor
نویسندگان
چکیده
Although several studies have explored the rGO-ZnO nanocomposites gas sensing properties towards many gases, only a few are devoted to ozone detection. This paper explores novel synthesis procedure of based upon two-step physical process. Namely, reduction process GO carried out using UV laser radiation followed by deposition ZnO nanoparticles on rGO surface RF-magnetron Sputtering. Our results demonstrate that film produces stable and conductive material with larger area. Consequently, this is able operate at high temperatures exhibited limit detection (LOD) in range 100 ppt, while pure LOD vicinity 1 ppb.

ppt level detection of samarium(III) with a coated graphite sensor based on an antibiotic.
N-[2-[4-[[[(Cyclohexylamino)carbonyl]amino]sulfonyl]phenyl]ethyl]-5-methyl pyrazine carboxamide (glipizid) was explored as an electro-active material for preparing a polymeric membrane-based sensor selective to samarium ions. The membrane incorporated 30% poly(vinyl chloride) (PVC), 53% benzyl acetate (BA), 11% glipizid and 6% sodium tetraphenyl borate. When coated on the surface of a graphite ...

The Effects of Nano In2O3 and ZnO on the CO Gas Detection of the SnO2 Sensor
The pellet-type SnO2 sensor was synthesized by the solid state method and the effects of additives such as nano ZnO (1-12 mol %) and nano In2O3 (1-10 mol %) on the CO gas sensitivity of sensor were investigated. The optimum sintering temperature was chosen 800°C because of the porosity content of the samples. The phase analysis and microstructure of the samples were studied by x-ray diffraction...

Transferable ZnO tetrapods were grown by an aqueous solution method. An individual ZnO tetrapod-based sensor was fabricated by in situ lift-out technique and its ultraviolet (UV) and gas sensing properties were investigated. This single tetrapod-based device responds to the UV light rapidly and showed a recovery time of about 23 s. The sensitivity of a single ZnO tetrapod sensor to oxygen conce...
متن کاملZnO Nanostructure-Based Intracellular Sensor
Recently ZnO has attracted much interest because of its usefulness for intracellular measurements of biochemical species by using its semiconducting, electrochemical, catalytic properties and for being biosafe and biocompatible. ZnO thus has a wide range of applications in optoelectronics, intracellular nanosensors, transducers, energy conversion and medical sciences. This review relates specif...
