Nanocomposites of pre-oxidized Ti3C2Tx MXene and SnO2 nanosheets for highly sensitive and stable formaldehyde gas sensor

Gaoqiang Niu et al.

Summary: Nanocomposites of pre-oxidized Ti3C2Tx MXene and SnO2 nanosheets are synthesized and annealed for formaldehyde sensors. The pre-oxidized Ti3C2Tx MXene prevents further degradation, and its effects are verified through various characterizations. The SnO2/MXene nanocomposites exhibit high response, low detection limit, good selectivity, excellent reproducibility, and superior long-term stability. The sensing properties are attributed to the synergistic effect between the pre-oxidized Ti3C2Tx MXene and the SnO2 nanosheets.

Self-stacked Co(OH)2/Co3O4 nanosheets for high-selectivity gas sensor to n-butyl alcohol

Zhongyue Zhang et al.

Summary: This study presents a facile route to synthesize self-stacked structure-based Co(OH)2/Co3O4 nanosheets material using a one-step hydrothermal technique. The resulting nanomaterial-based gas sensor exhibits excellent selectivity and sensitivity in detecting n-butyl alcohol. By employing a combination of X-ray photoelectron spectroscopy and transform infrared spectrometry (FTIR), the potential mechanism of gas sensing is discussed. It is suggested that the increased concentrations of oxygen vacancy and intramolecular dehydration phenomenon might contribute to the gas sensing mechanism of n-butyl alcohol.

Understanding the Increasing Trend of Sensor Signal with Decreasing Oxygen Partial Pressure by a Sensing-Reaction Model Based on O2-Species

Liupeng Zhao et al.

Summary: This study proposes a sensing model based on previous experimental and theoretical results to explore the mechanism of the effect of oxygen partial pressure on sensor signals. The main oxygen species is found to be O2, and a functional relationship between surface electron concentration, oxygen partial pressure, and reducing gas concentration is established based on the band bending of SnO2 and different oxygen partial pressures. The results of this study provide guidance for accurate gas detection under varying oxygen partial pressure.
