Direct or Indirect Sonication in Ecofriendly MoS Dispersion for NO and NH Gas-Sensing Applications.

Unlike the most used, this study explores the effects of direct and indirect sonication methods on the dispersion and gas sensing performance of MoS nanoflakes. The obtained dispersions are characterized using various techniques, such as field emission scanning electron microscopy, high resolution transmission electron microscopy, atomic force microscopy, dynamic light scattering, and Raman and X-ray diffraction, to evaluate their morphological and structural properties. Gas sensing measurements are conducted using exfoliated MoS on interdigitated electrode structures, and the response to multiple gases is recorded.
