Abstract
SnO2 has been extensively used in the detection of various gases. As a gas sensing material, SnO2 has excellent physical-chemical properties, high reliability, and short adsorption-desorption time. The application of the traditional SnO2 gas sensor is limited due to its higher work-temperature, low gas response, and poor selectivity. Nanomaterials can significantly impact gas-sensitive properties due to the quantum size, surface, and small size effects of nanomaterials. By applying nanotechnology to the preparation of SnO2, the SnO2 nanomaterial-based sensors could show better performance, which greatly expands the application of SnO2 gas sensors. In this review, the preparation method of the SnO2 nanostructure, the types of gas detected, and the improvements of SnO2 gas-sensing performances via elemental modification are introduced as well as the future development of SnO2 is discussed.
期刊介绍：
Nano Materials Science (NMS) is an international and interdisciplinary, open access, scholarly journal. NMS publishes peer-reviewed original articles and reviews on nanoscale material science and nanometer devices, with topics encompassing preparation and processing; high-throughput characterization; material performance evaluation and application of material characteristics such as the microstructure and properties of one-dimensional, two-dimensional, and three-dimensional nanostructured and nanofunctional materials; design, preparation, and processing techniques; and performance evaluation technology and nanometer device applications.
