摘要

The present work reports the synthesis of magnesium oxide nanoparticles (MgO NP’s) using A. barbadensis Mill (aloe vera) as the stabilizer by green synthesis approach as well as solution-combustion method. The morphological, structural and optical properties of synthesized MgO NP’s were characterized by transmission electron microscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction. The characterization results show the fibrous shaped porous structure of synthesized MgO NP’s with size range of 2–25 nm. The as-synthesized MgO NP’s were subjected to sensing of liquefied petroleum gas (LPG) having different concentration ranges (400–1000 ppm) and different operating temperatures along with dynamic characteristics. The sensor exhibits high selectivity and sensitivity towards LPG.
