“…The special nanoflower-like structure [26] not only facilitates a good connection between each SnS structure, but also maintains a large retention space for gas diffusion and adsorption. In this case, most of the active centers [27] in the sensing layer consisting of SnS nanosheets can be efficiently used for the contact reaction, which significantly improves their strength. 2d), we can clearly see its elemental composition; In Table 1, the atomic percentage between S and Sn is close to 1:1, indicating that the prepared sample is SnS, which again indicates the successful synthesis.…”

In this work, flower-like stannous sulfide (SnS) nanomaterials are synthesized using a hydrothermal method and used as sensitive materials for cataluminescence (CTL)-based detection of diethyl ether. Gas sensors based on SnS nanomaterials are prepared, and the SnS nanomaterials exhibit excellent gas-sensitive behavior towards ether. High sensitivity to ether is achieved at a relatively low operating temperature (153 °C) compared to other common sensors. The response time is 3 s and the recovery time is 8 s. The CTL intensity shows a good linear relationship (R2 = 0.9931) with a detection limit of 0.15 ppm and the concentration of ether in the range of 1.5–60 ppm. The proposed CTL sensor shows good selectivity towards ether. In addition, a highly stable signal is obtained with a relative standard deviation of 1.5%. This study indicates that the SnS-based sensor has excellent gas-sensitive performance and shows potential for applications in the detection of ether.

Herein, carbon dots (CDs) as biocompatible, fluorescent carbon-based nanomaterials were synthesized from papaya seed waste as renewable carbon sources for the first time via a facile acid pyrolysis method. The papaya seed-derived CDs showed blue fluorescence emission under UV light (365 nm) with a quantum yield of 2.74%, and contained oxygen-, and nitrogen- containing functional groups. Due to their surface functionality, the CDs have a great potential for using as fluorescence sensing probe in metal ion sensing application. The CD solution exhibited the most selective detection to Cu2+ as presented the highest fluorescence quenching with the limit of detection (LOD) of 5.16 μM. The CD-paper-based fluorescent sensor was also developed for practical application, and the RGB value was used to compare the sensitivity of CDs toward metal ions. The CD sensing film was also prepared for diethyl ether vapor sensing via optical electronic nose system. The principal component analysis (PCA) score plots revealed the total variance of 99.3%, indicating that the CDs can be used to discriminate different concentrations of diethyl ether/ethanol vapor mixtures. This work demonstrated that the papaya seed-derived CDs have a great attention to be alternative materials for developing sensing materials in both solution and film forms.

MgO surface makes it easy to introduce a certain amount of oxygen vacancy and can enhance catalytic reaction activity. Besides, as a silicoaluminate mineral material, halloysite nanotube (HNT) has a unique tubular structure. In this paper, the HNTs@MgO composite was successfully synthesized based on natural clay material HNTs as a carrier, and the CTL sensor based on HNTs@MgO was successfully developed for the rapid determination of ether in air. The HNTs@MgO material was characterized by a series of means such as SEM, XPS, and XRD, which clearly confirmed that MgO successfully combined with HNTs. And the sensor showed good sensitivity and selectivity, with a good linear relationship between CTL intensity and ether concentration in the range of 0.5–190.0 mg/L (R2 = 0.9942), and the limit of detection (LOD) was 0.18 mg/L (S/N = 3). The RSD values of the results of 11 consecutive measurements by the same sensor and 7 days of consecutive measurements were 1.96% (n = 11) and 3.42% (n = 7), showing good repeatability and reproducibility. At last, the CTL sensor was used to detect air samples, the recoveries ranged from 91.6% to 109.6%. Thus, it was concluded that HNTs@MgO composite is a cost‐effective and promising material with potential application in atmospheric detection.
