One-Dimensional Nanomaterials in Resistive Gas Sensor: From Material Design to Application

With a series of widespread applications, resistive gas sensors are considered to be promising candidates for detection, benefiting from their small size, ease-of-fabrication, low power consumption and outstanding maintenance properties. One-dimensional (1-D) nanomaterials, which have large specific surface areas, abundant exposed active sites high length-to-diameter ratios, enable fast charge transfers gas-sensitive reactions. They can also significantly enhance the sensitivity response speed sensors. The features sensing mechanism current potential advantages 1-D nanomaterials in firstly reviewed. This review systematically summarizes design optimization strategies high-performance sensors, including doping, heterostructures composites. Based on monitoring requirements various characteristic gases, available applications this type classified reviewed three categories environment, safety health. direction priorities future development laid out.
