This paper outlines the research on gas sensors composed of various dimensional nanomaterials and proposes that nanomaterials have the potential to become the new generation of gas sensors due to their high sensing efficiency, good detection capability, and high sensitivity. The paper also reviews the physical sensors formed from nanomaterials, the methods used, characteristics, and advantages of each type of sensor, as well as the research on gas sensors composed of different nanomaterials. It compares and analyzes the main characteristics of gas sensors with various dimensions of nanomaterials and summarizes the development direction of gas sensors based on various dimensions of nanomaterials.
Nanomaterials-based gas sensors have great potential for substance detection. This paper first outlines the research of gas sensors composed of various dimensional nanomaterials. Secondly, nanomaterials may become the development direction of a new generation of gas sensors due to their high sensing efficiency, good detection capability and high sensitivity. Through their excellent characteristics, gas sensors also show high responsiveness and sensing ability, which also plays an increasingly important role in the field of electronic skin. We also reviewed the physical sensors formed from nanomaterials in terms of the methods used, the characteristics of each type of sensor, and the advantages and contributions of each study. According to the different kinds of signals they sense, we especially reviewed research on gas sensors composed of different nanomaterials. We also reviewed the different mechanisms, research processes, and advantages of the different ways of constituting gas sensors after sensing signals. According to the techniques used in each study, we reviewed the differences and advantages between traditional and modern methods in detail. We compared and analyzed the main characteristics of gas sensors with various dimensions of nanomaterials. Finally, we summarized and proposed the development direction of gas sensors based on various dimensions of nanomaterials.
