One-step fabrication of SnO2 porous nanofiber gas sensors for sub-ppm H2S detection

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

“…The sensing layer with smaller activation energy has been demonstrated showing higher gas sensitivity of the sensor. 34,35 The activation energy (E a ) of the MoS 2 ower-like nanostructures can be calculated through the temperaturedependent conductivity as expressed by the Arrhenius eqn (4) as follows: 34…”

Reduced Graphene Oxide (rGO)-Loaded Metal-Oxide Nanofiber Gas Sensors: An Overview

“…In general, the electrospinning technique can be used to fabricate continuous fibers with the possibility of control over the fiber diameter [ 22 ]. In addition, different NFs, such as porous NFs [ 23 ], core-shell NFs [ 24 , 25 ], and complex NFs [ 26 ], can be easily synthesized by electrospinning. Furthermore, NFs with controllable alignment can be produced by modifying the electrospinning [ 27 ].…”

Advances in Doped ZnO Nanostructures for Gas Sensor

“…Hitherto, various MOSs have been found to be suitable for sensing materials, such as SnO 2 , WO 3 , TiO 2 , In 2 O 3 , ZnO, etc [6a,b,c,d] . Among them, ZnO is an important multi‐functional n‐type semiconductor material with a wide band gap of 3.37 eV, a large exciton binding energy of 60 meV and a high hall mobility of 200 cm 2 v −1 s −1 at room temperature [7] .…”
