Monitoring toxic chlorine (Cl2) at the parts-per-billion (ppb) level is crucial for safe usage of this gas. Herein, ZnO, WO3, and SnO2 nanowire sensors were fabricated using an on-chip growth technique with chemical vapor deposition. The Cl2 gas-sensing characteristics systematically investigated. Results demonstrated that nanowires exhibited higher sensitivity to gas than ZnO WO3 nanowires. response (RCl2/Rair) sensor 50 ppb °C was about 57. Hence, can be excellent sensing material...
Schottky junctions (SJ) are considered devices for sensing applications due to their unique properties. Herein, we report on the design, facile fabrication, and outstanding NO2 gas properties of monolayer graphene (GP)/SnO2 nanowire (NW) SJ devices. The were prepared by directly growing single crystal SnO2 NWs interdigitated Pt electrodes via thermal evaporation, followed transferring a GP layer grown chemical vapor deposition top NW chip. SJ-based sensor showed reversible response at...
Controlled synthesis of ultrathin MoS<sub>2</sub>nanoflowers is crucial to develop a high-performance room-temperature NO<sub>2</sub>gas sensor for the future integration sensors into smart, portable and Internet-of-Things (IoT)-based devices.
Development and/or design of new materials structures for effective gas sensor applications with fast response and high sensitivity, selectivity, stability are very important issues in the technology. This critical review introduces our recent progress development meso‐/nanoporous semiconducting metal oxides their to sensors. First, basic concepts resistive sensors synthesis introduced. The advantages also presented, taking into account crystallinity ordered/disordered porous structures....
