Abstract
Herein we report the synthesis, triethylamine gas sensing, and photocatalytic activity of Sn doped NiO (SNO) nanoparticles prepared by solvothermal technique. X-ray diffraction (XRD), Raman Spectroscopy, field emission-scanning electron microscopy (FE-SEM), Transmission electron microscopy (TEM), UV–visible (UV–vis) spectroscopy, X-ray photoelectron spectroscopy (XPS), were used to characterize the structural, optical properties, elemental composition and charge state of SNO particles. were given by. The crystallite size of the SNO nanoparticles ranged from 24 nm to 9 nm. FESEM and TEM analysis confirmed the presence of quasi-spherical nanoparticles. From UV–vis spectroscopy, the bandgap energy was determined as 3.38 eV–3.61 eV. Triethylamine sensing response of SNO nanoparticles can reach up to 8.2 for the concentration of 100 ppm at an operating temperature 260 ˚C. Photocatalytic activity results demonstrated Rhodamine B dye degradation (∼82%) in 180 mins under UV light irradiation.
