In the era of intelligent big data with the rapid expansion of information, real-time detection is becoming an essential criterion for evaluating gas sensors. It is of great significance for the rapid and precise detection of hazardous volatile gases such as n-propanol. In this study, the nanorod-like semiconductor metal sulfide CdS coated with reduced graphene oxide (rGO) nanosheets was utilized to construct a high-performance sensor capable of ultrarapid and accurate n-propanol detection. The sensor based on the CdS/rGO nanocomposite with 0.5 wt% rGO (CG-5) exhibited only 1 s for both response and recovery time to 100 ppm n-propanol, which were shortened by 13 and 2 times compared to pristine CdS, respectively. Meanwhile, the sensor response of CG-5 enhanced 3-fold that of pristine CdS. Additionally, the hydrophobic rGO component in the hybrid endowed the sensor with a strong moisture-interference resistance over 20–98% relative humidity. The excellent selectivity, repeatability, and long-term stability for n-propanol detection were demonstrated as well. The exceptional enhancement in the sensing performance of CG-5 can be ascribed to several contributing factors, including its geometric configuration, weakened hydrophilicity, lowered activation energy, and additional active sites at the heterointerface between CdS and rGO. The rational design of CG-5 made it a promising candidate for the rapid, sensitive, and reliable detection of n-propanol.

“…Therefore, the optimum working temperature for the subsequent gas-sensing test was set at 120 °C. The maximum response value is 120.5 at 120 °C in detecting 100 ppm n -propanol, which is higher than other n -propanol sensors, ,,,− and also higher than the response (6.5) of HoFeO 3 sensor based on the contrast sample to 100 ppm n -propanol at its optimum working temperature of 150 °C (Figure S6).…”

“…The high responses over the concentration range of 50− 1000 ppb and the low detection limit are conspicuous among the published materials (as shown in Figure 4(d)), such as double-shell Cu 2 O, ZnSnO 3 nanospheres, and ZnO/NiO heterostructure, and have been further compared with our work.

The sensitive detection of n-propanol, a typical marker molecule in respiratory gases for lung cancer, has attracted much attention from the consideration of health in modern society. However, the identification of n-propanol at the sub-ppm level with rapid responsive ability is a significant challenge but very critical for the early diagnosis of lung cancer. Herein, we demonstrate a unique chromosome-like HoFeO 3 nanostructure material, prepared by annealing the self-sacrificial template of easily accessible HoFe-(CN) 6 , for high-performance n-propanol sensing. In detecting npropanol, the HoFeO 3 material-based sensor exhibits a response of 120.5 to 100 ppm of n-propanol at an operating temperature of 120 °C. Most importantly, it shows a low detection limit of 50 ppb and a good linear relationship between response and concentration. This sensor also possesses a rapid responsive ability with a response time of 4 s. The remarkable sensing performance, greatly outperforming other conventional semiconductor-based chemiresistive gas sensors, can be mainly attributed to the mesoporous structure, various surface element states, and narrow-band traits. The homemade experiment system further validates the practical potential of HoFeO 3 microchromosome-based gas sensors for early-stage lung cancer diagnosis.

“…The synergistic effects of the catalytic and electronic promotion of Pt enhance the sensitivity of the Pt-doped ZnO porous thin film-based sensor to NH 3 and reduce the cross-sensitivity to common interfering gases. Yuan and co-workers [86] successfully prepared NiO-In 2 O 3 porous ordered thin films by ethanol-assisted self-assembly method and solution impregnation transfer method (Figure 12g). Compared with the pure In 2 O 3 thin film, the heterostructure formed by doping NiO has a higher response value, faster response, and recovery time (Figure 12h,i).…”

Semiconductor gas sensors are widely used in the fields of health, safety, energy efficiency, and emission control owing to their high sensitivity, low power consumption, and small size. Among them, the thin film‐based semiconductor gas sensors have excellent sensing characteristics due to their controllable morphology and large specific surface area, which can effectively improve the sensitivity of the gas sensors and shorten the response and recovery time. Gas–liquid interfacial self‐assembly method is an effective method for fabricating thin films, which can be utilized to construct large wafer‐scale thin films on the liquid surface. In this review, the advantages of thin films prepared by gas–liquid interfacial self‐assembly method are introduced. Subsequently, the recent progress in the preparation of thin films by gas–liquid interfacial self‐assembly method and their applications in semiconductor gas sensors are reviewed and summarized, mainly from two aspects of organic materials and inorganic materials. In the end, the technology is prospected, and it is considered that there is still much room for improvement and optimization in the future.
