Hierarchical hollow MoS2 microspheres as materials for conductometric NO2 gas sensors

Controlled synthesis of ultrathin MoS2nanoflowers for highly enhanced NO2sensing at room temperature

“…† This result can be attributed to the presence of water molecules in the humid ambience, which interact with lattice sites and/or defects on the MoS 2 nano-owers, thereby decreasing the number of active sites for the adsorption of the tested gas. 41,50 The large number of water molecules at high RH ambience results in less active sites and reduced surface area, thereby decreasing the gas response. 41,50 However, the reduction in the response is small because the water molecules on the MoS 2 surface are already abundant at 60% RH.…”

Thus, further increasing the RH to 90% contributes insignicantly to further decreasing the number of active sites on the MoS 2 nanoowers.…”

Morphological Characteristics of Molybdenum Disulfide and Current Application on Detecting SF6 Decomposing Products

“…As an n-type semiconductor material with wide band gap, MoS 2 receives the most interest because of its high surface activity and chemical stability (Fan et al, 2017;Zhang et al, 2019). Up to now, a large number of studies have been carried out on the various nanostructures of MoS 2 , including nanoflakes (Johari et al, 2020), nanotubes (Zhong et al, 2020), nanospheres (Li Y. X. et al, 2019) and other complex hierarchical nanostructures (Zhang et al, 2018b;Agrawal et al, 2020), to realize more effective methods of detecting SF 6 decomposed products. Besides, the evident correlation has been confirmed between unique structures and performances (Barzegar et al, 2019;Wang et al, 2020).…”
