An inexpensive single-step carbon-assisted thermal evaporation method for the growth of SnO2-core/ZnO-shell nanostructures is described, and ethanol sensing properties are presented. The structure phases grown investigated by field-emission scanning electron microscopy (FESEM), transmission (TEM) X-ray diffraction (XRD) techniques. XRD analysis indicates that core-shell have good crystallinity. At a lower duration 15 min, only SnO2 nanowires with rectangular cross-section observed, while ZnO...
This work reports the fabrication of mixed structure ZnO nanorod on SnO2 thin film via spray pyrolysis followed by thermal annealing and their gas sensing properties. ZnO/SnO2 nanostructures are successfully prepared a gold interdigitated alumina substrate spraying varying precursor concentrations zinc acetate tin (IV) chloride pentahydrate solutions in ethanol annealing. The morphology is controlled tailoring Zn:Sn ratio solution mixture. Unique crystals nanorods observed under field...
Ternary nanocomposites synergistically combine the material characteristics of three materials, altering desired charge storage properties such as electrical conductivity, redox states, and surface area. Therefore, to improve energy synergistic SnO2, TiO2, three-dimensional graphene, herein, we report a facile hydrothermal technique synthesize ternary nanocomposite graphene-tin oxide-titanium dioxide (3DG-SnO2-TiO2). The synthesized was characterized using characterization techniques XRD,...
In this research work, the sensitivity of TiO2 nanoparticles towards C2H5OH, H2 and CH4 gases was investigated. The morphology phase content particles preserved during sensing tests by prior heat treatment samples at temperatures as high 750 °C 1000 °C. Field emission scanning electron microscopy (FESEM), transmission (TEM) X-ray diffraction (XRD) analysis were employed to characterize size, particles. For sensor fabrication, a film printed on Au interdigitated alumina substrate. temperature...
An ethanol gas sensor with enhanced response was fabricated using Ni-doped SnO2 nanorods, synthesized via a simple hydrothermal method. It found that the (R = R0/Rg) of 5.0 mol% (5.0Ni:SnO2) nanorod 1.4 × 104 for 1000 ppm C2H5OH gas, which is about 13 times higher than pure (1.1 103) at operating temperature 450 °C. Moreover, 50 5.0Ni:SnO2 still recorded significant reading, namely 2.0 103 time 30 s and recovery 10 min. To investigate effect Ni dopant (0.5–5.0 mol%) on structural...
Tin (IV) oxide (SnO2) nanostructures are regarded as one of the most popular materials for conventional gas sensors, due to their high surface area and fast response in regard reducing oxidizing gases. However, operating temperature (>200 °C) leads power consumption limits applications. Here, a new nanocomposite fiber materials, consisting undoped doped (nickel palladium) SnO2 nanorods, polyaniline (PANI), polyhydroxy-3-butyrate (P3HB) synthesized via hydrothermal method,followed by an situ...
