Effect of post-oxidation processes and thickness of SnO2 films prepared by vacuum evaporation on CO gas sensing characteristics

Amit Kumar Mauraya et al.

Summary: This report discusses the effects of post-oxidation processes and thickness of SnO2 thin films on their physical properties and CO gas sensing characteristics. The results show that SnO2 films produced by direct-oxidation method exhibit higher CO sensitivity, with thinner films showing even higher sensitivity and selectivity towards CO gas compared to step-oxidized films.

Monodispersed hollow α-Fe2O3 ellipsoids via [C12mim] [PF6]-assistant synthesis and their excellent n-butanol gas-sensing properties

Ping Wang et al.

Summary: Monodisperse alpha-Fe2O3 hollow ellipsoids were successfully fabricated with the addition of [C(12)mim][PF6] (IL) using a simple one-pot method, revealing the significant influence of calcination temperature and IL content on the structures. Gas sensors based on IL-loaded alpha-Fe2O3 hollow ellipsoids exhibited high response, sensitivity, and low detection limit to n-butanol, showing their potential as promising candidates for highly sensitive gas sensors.

Selective ppb-level NO2 gas sensor based on SnO2-boron nitride nanotubes

Bharat Sharma et al.

Summary: This paper demonstrated a hybrid SnO2-BNNTs sensor for trace ppb-level NO2 detection, with a low detection limit and better sensor response than the SnO2 sensor. The sensing characteristics of the sensor were studied, including response, repeatability, stability, and response-recovery time. The increased space charge depleted regions at the p-n heterojunction promoted a tunneling effect and provided conducting channels through BNNTs for an improved sensor response.

Flexible fabric gas sensors based on reduced graphene-polyaniline nanocomposite for highly sensitive NH 3 detection at room temperature

Guifang Luo et al.

Summary: A flexible fabric gas sensor for detecting sub-ppm-level NH3 was developed, showing fast response, long-term stability, and low detection limit. The high sensitivity of the sensor is mainly attributed to its distinctive 1D fiber structure and the p-p heterojunction between rGO nanosheets and PANI.
