Interaction of functionalized Ga2O3 NW-based room temperature gas sensors with different hydrocarbons

Highly selective low-temperature triethylamine sensor based on Ag/Cr2O3 mesoporous microspheres

“…Mazeina et al [31] reported that the Ga 2 O 3 nanowires functionalized with acetic and pyruvic acid showed response to TEA at room temperature, but the high detection limit, low sensitity and long response/recovery times made it beyond the scope of our concern.…”

Room-temperature high-performance acetone gas sensor based on hydrothermal synthesized SnO2-reduced graphene oxide hybrid composite

“…The three curves demonstrated the stability for the SnO 2 -RGO sensor exposed to 10, 50 and 200 5 ppm acetone gas, and there is no significantly change among the measurement at least 30 days. Table 1 presents the performance of the proposed acetone gas sensor working at room-temperature in comparison with previous reports [37][38][39][40][41] . The response and measurement range for the prepared sensor are comparable to 10 those of the sensor made from metal oxides or polymers.…”

Formation of Oxide Nanowires by Thermal Evaporation and Their Application to Gas Sensors

“…They have also been studied as sensors for detecting reducing gases such as H 2 , CO, CH 4 (Fleisher et al, 1992;Schwebel et al, 1998). Ga 2 O 3 nanowires have also been studied as gas sensing materials Mazeina et al, 2010). In our study, a gallium grain (99.999%, 0.5 g) was placed on an alumina substrate in an alumina boat .…”
