Improved Ethanol Sensing Performance of α-MnO2 Nanorods at Room Temperature Enabled through PPy Embedding

“…Thus, the maximum surface area can provide the sensor with a faster response and better sensitivity. [24][25][26][27]58 MnO 2 is an n-type semiconducting material, and electrons are the majority carriers. 37 When exposed to air, oxygen molecules in the air are chemisorbed on the material surface.…”

“…A NiCo 2 O 4 /WO 3 composite prepared by a two-step hydrothermal method showed excellent NO 2 sensing performance at a low operating temperature (150°) . Again, a n–n heterojunction-based ZnO-modified SnS 2 sensor showed a higher response to H 2 S at 180 °C with a lower detection limit of 50 ppb and excellent stability . A LaF 3 –SnS 2 sensor was prepared for the real-time detection of H 2 S with a lower detection limit of 50 ppb .…”

“…25 Again, a n−n heterojunction-based ZnO-modified SnS 2 sensor showed a higher response to H 2 S at 180 °C with a lower detection limit of 50 ppb and excellent stability. 26 A LaF 3 −SnS 2 sensor was prepared for the real-time detection of H 2 S with a lower detection limit of 50 ppb. 27 Moreover, an n− n heterojunction-based In 2 O 3 /SnS 2 self-powered gas sensor detected ultralow concentrations of NO 2 at room temperature.…”

SnSe2/Ag2Se heterostructures with an accumulation layer for rapid and sensitive detection of NO2

“…Two-dimensional (2D) metal chalcogenides are used in various fields, such as electrocatalysts, photocatalysts, and sensors. [20][21][22][23][24][25] Especially, owing to the large surface area, high reactive activity, and outstanding carrier mobility, 2D metal chalcogenides, such as SnS 2 [26][27][28][29] and MoS 2 , 30 have been increasingly investigated for gas sensors. Compared with SnS 2 , SnSe 2 has a narrower band gap, wider layer spacing, and higher carrier mobility.…”

“…35 Additionally, non SnO 2 -based materials also have been used to detect H 2 S gas such as SnO 2 /rGO/polyaniline (PANI) ternary nanocomposite, 36 CuO/MoS 2 , 37 metal organic framework-derived α-Fe 2 O 3 hollow nanospheres modified with MoSe 2 nanoflowers, 38 LaF 3 quantum dot (QD)-modified SnS 2 nanorod 39 and SnS 2 nanowires modified with ZnO nanorods. 40 Gupta et al 28 successfully fabricated a multilayered structure of CuO–SnO 2 , yielding a remarkable response of 27 000 towards 20 ppm H 2 S at a working temperature of 140 °C. Lee et al 29 developed CuO-loaded SnO 2 hollow spheres, exhibiting a response of 3.13 towards 1 ppm H 2 S at a working temperature of 300 °C and 80% relative humidity (RH).…”
