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.

“…76 The toluene gets oxidized to excited state CO 2 *, which emits a luminescent signal while returning to the ground state. Here, a carbon nanotube-based platinum-decorated Pt/Ti 3 C 2 T x -CNT catalyst was immobilized on ceramic rods to sense toluene with a LOD of 2 ppm, 77 tested against 10 other VOCs (toluene, trichloromethane, tetrachloroethane, cyclohexane, formaldehyde, diethyl ether, acetone, carbon dioxide, ammonia, and ethanol). The optimum working temperature was 150 °C for such a sensor, lower than other sensors used for the same purpose 78 (Table 3, entry 9).…”

The implementation of hydrogen, as a renewable and clean energy source, has the potential to replace fossil fuels and to decarbonize hard-to-abate sectors, enabling sustainable development with a lower environmental footprint. At concentrations higher than 4 vol %, hydrogen is, however, highly flammable and real-time monitoring and detection are required to ensure safe operation during production, storage, transportation, and utilization of it. Hydrogen sensors shall, therefore, be both efficient and sensitive to operate across a wide range of concentrations and mixtures with other gases. Current commercial hydrogen sensors are primarily dependent on electrochemical, heat-conductance, or calorimetric technologies, being intrinsically developed from noble and expensive metals or complex setups. Portable hydrogen sensing technologies for personal protective equipment in remote and confined areas shall, however, require them to be selective and specific, light weight, and mobile, as well as self-regenerating and stable for the long-term. An emerging type of hydrogen sensor involves biosensing through biological pathways whereby hydrogenase is extracted from microbial communities and used for carrying out the reversible hydrogen oxidation reaction, allowing sensitivity down to 0.4 ppb in complex environments. Microbial communities innately use hydrogen for metabolic activities related to growth and energy synthesis. This review highlights the recent developments in hydrogen biosensing while presenting viable options for on-site and fast hydrogen detection, allowing timely action for mitigating risks related to hydrogen leakages and inflammation. Beyond discussing the mechanisms and materials used to generate hydrogen biosensors, a critical comparison with conventional hydrogen and other gaseous sensors is presented, highlighting the opportunities and remaining challenges in this field.

“…Toluene has been identified as a biomarker for lung cancer, and thus the detection of toluene may serve as an indication of the existence of lung cancer [ 82 ]. A new 2D nanocomposite comprised of Pt/Ti 3 C 2 T x -carbon nanotube was synthesized and tested for quick diagnosis of lung cancer [ 83 ]. Also, this sensor offered a relatively low LOD of close to 2 ppm and a working temperature of around 150 °C, which is lower than similar reported sensors.…”

Sensors play vital roles in industry and healthcare due to the significance of controlling the presence of different substances in industrial processes, human organs, and the environment. Electrochemical sensors have gained more attention recently than conventional sensors, including optical fibers, chromatography devices, and chemiresistors, due to their better versatility, higher sensitivity and selectivity, and lower complexity. Herein, we review transition metal carbides (TMCs) and transition metal oxides (TMOs) as outstanding materials for electrochemical sensors. We navigate through the fabrication processes of TMCs and TMOs and reveal the relationships among their synthesis processes, morphological structures, and sensing performance. The state-of-the-art biological, gas, and hydrogen peroxide electrochemical sensors based on TMCs and TMOs are reviewed, and potential challenges in the field are suggested. This review can help others to understand recent advancements in electrochemical sensors based on transition metal oxides and carbides.
