Metal oxide-based chemo-resistive nanostructured gas sensors for environment and human safety: a review
Keywords:
nanomaterial, sensitivity, gas sensor, Metal Oxide Semiconductor (MOS)Abstract
Industrialization and its progress are very important for the economy and to move towards prosperity, stimulating innovation and creating jobs. Nonetheless, industrialization has negative impacts, if not done judiciously, such as pollution, increased greenhouse gas emissions and global warming. Therefore, amenity-with-security is of fundamental significance in a new and dynamic lifestyle. A gas sensor is one of the crucial devices for monitoring and subsequently preserving the clean atmosphere among a number of other safety technologies. In-depth assessments of gas sensors and their necessity in the environment (air) pollution are provided in the current review. With a special emphasis on metal oxide semiconductor (MOS)-based gas sensors, the study of gas sensors and the factors relating to sensing mechanisms. It not only describes the basic concepts and brief history of gas sensors,
