Abstract

Mesoporous TiO2 nanoparticles were successfully synthesized via solvothermal. The morphology and crystal structure was characterized by UV–vis spectrum (UV-Vis), Fourier Transform Infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Scanning electron microscopy (SEM) and transmission electron microscopy (TEM).   All the observations confirmed that the as-fabricated mesoporous TiO2 nanoparticles were successfully synthesized with surface Plasmon resonance peak between a range of 250-350 nm, and its pattern meets with the JCPDS Standard (card No. 21-1272). TEM confirmed the mesoporous structure morphology and shows the incredible gas sensing performance due to their large accessible surface area. Furthermore, the as-prepared TiO2 nanoparticles exhibited more rapid response/recovery and higher sensitivity towards ethanol at 180°C, distinguished with isopropyl alcohol and methanol. Besides, it can be affirmed that the synthesized mesoporous TiO2 nanoparticles are a promising applicant for fabricating high-performance ethanol gas sensor in real-time monitoring.
