Single atom catalysts (SACs) have received enormous attention in the field of catalysis in the last decade due to their maximum atom utilization as well as unique physical and chemical properties. For the semiconductor-based electrical gas sensor, the core is the catalysis process of target gas molecules on the sensitive materials. In this scenario, the SACs would be used for highly sensitive and selective gas sensing, however, only some of bubbles come to the surface. To realize its practical applications, the preparation strategies for SACs are reviewed systematically. The aggregation and low loading of SACs are still the main challenges. Following, the interaction between the SACs and the target gas molecules and its supports is unrevealed to explain the improvement of sensing performances. Furthermore, the typical applications of SACs in the different gases sensing are highlighted, revealing its superiority of high sensitivity and selectivity. Finally, the challenges and future perspectives on the SACs based gas sensing are presented.

“…Metal oxide semiconductors, which play a crucial role in gas sensing applications, are divided into two distinct groups based on their majority carriers. N-type MOSs, such as ZnO [62,63], In 2 O 3 [64,65], Fe 3 O 2 [62,66], TiO 2 [67,68], WO 3 [69,70], and SnO 2 [71,72], exhibit electrons as their majority carriers, whereas p-type semiconductors, including NiO [73], Co 3 O 4 [74], Cr 2 O 3 [75], Mn 3 O 4 [76], and CuO [77], have holes as their majority carriers.…”

An electronic nose, designed to replicate human olfaction, captures distinctive ‘fingerprint’ data from mixed gases or odors. Comprising a gas sensing system and an information processing unit, electronic noses have evolved significantly since their inception in the 1980s. They have transitioned from bulky, costly, and energy-intensive devices to today’s streamlined, economical models with minimal power requirements. This paper presents a comprehensive and systematic review of the electronic nose technology domain, with a special focus on advancements over the last five years. It highlights emerging applications, innovative methodologies, and potential future directions that have not been extensively covered in previous reviews. The review explores the application of electronic noses across diverse fields such as food analysis, environmental monitoring, and medical diagnostics, including new domains like veterinary pathology and pest detection. This work aims to underline the adaptability of electronic noses and contribute to their continued development and application in various industries, thereby addressing gaps in current literature and suggesting avenues for future research.
