“…The gas sensing properties of the biosynthesized Ni-doped SnO 2 nanoparticles thin film is also investigated for different gases like NH 3 , LPG and H 2 S. For better comparison of NO 2 gas sensing properties of the biosynthesized Ni-doped SnO 2 , both pure SnO 2 and Ni-doped SnO 2 nanoparticles were synthesized using a chemical method (sol-gel) as mentioned elsewhere 31 and their NO 2 gas sensing properties were explored. Thereafter, the soaked seeds were removed and the extract was filtrated using a glass-fiber filter (GF/F) to be free from particulate matter.…”

Considering the potential applications of transition metal doped nanostructured materials and the advantages of novel, cost-effective and environmental friendly biosynthesis methods, Ni-doped SnO2 nanomaterials have been synthesized using remnant water (ideally kitchen waste) collected from soaked Bengal gram beans (Cicer arietinum L.) extract. The structural and optical properties of the Ni-doped SnO2 nanostructures were studied using various techniques such as UV/visible spectroscopy, FT-IR spectroscopy, X-ray powder diffraction (XRD), Field-emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). The SEM, TEM images and XRD of biosynthesized Ni-SnO2 nanoparticles reveal uniform size distribution with the average size of 6 nm and confirmed the formation of rutile structure with space group (P42/mnm) and nanocrystalline nature of the products with spherical morphology.Subsequently, Ni-doped biosynthesized SnO2 nanoparticles were coated onto the glass substrate using doctor blade method to form thin films. The NO2 sensing properties of the materials have been studied in comparison with other gases.The reported gas sensing results are promising, which suggest that the Ni-dopant is a promising noble metal additives to fabricate low cost SnO2 based sensor.

“…Khuspe et al [29] reported the experimental results about SnO 2 based SO 2 sensors where SnO 2 had a sensitivity of 19% at 100 ppm NO 2 gas and working temperature at 200 ∘ C. In addition, recovery time and response time differed, depending on NO 2 concentration (10, 20, 40, 60, 80, and 100 ppm). The greater the NO 2 concentration, which is exposed to SnO 2 , the shorter the response time-there was a 90% reduction from 30 to the 7 seconds.…”

A significant amount of pollutants is produced from factories and motor vehicles in the form of gas. Their negative impact on the environment is well known; therefore detection with effective gas sensors is important as part of pollution prevention efforts. Gas sensors use a metal oxide semiconductor, specifically SnO 2 nanostructures. This semiconductor is interesting and worthy of further investigation because of its many uses, for example, as lithium battery electrode, energy storage, catalyst, and transistor, and has potential as a gas sensor. In addition, there has to be a discussion of the use of SnO 2 as a pollutant gas sensor especially for waste products such as CO, CO 2 , SO 2 , and NO x . In this paper, the development of the fabrication of SnO 2 nanostructures synthesis will be described as it relates to the performances as pollutant gas sensors. In addition, the functionalization of SnO 2 as a gas sensor is extensively discussed with respect to the theory of gas adsorption, the surface features of SnO 2 , the band gap theory, and electron transfer.

“…Also, SnO 2 based semiconductor sensors are preferred because of their simplicity, small dimensions, low cost, high reliability and relatively low operating temperature [5,6]. Crystallite size and specific surface area play important role on sensitivity, selectivity and reproducibility of SnO 2 sensors [7].…”
