Gas Sensing Materials Roadmap.

We have faced the challenges from atmosphere environment due to the exposing toxic gases or liquids. Moreover, we also need to test some gases such as acetone, ethanol, and petroleum for our health or safety. Therefore, it is important to develop various gas sensors for testing them. Sensing materials play important roles in determining the performance of gas sensors. Thus, a great deal of work has been focused on the material studies. In this content, we need to discuss different materials as gas sensing materials systematically, and further give comments on the status at present and future challenges. This inspire us to assemble this 2020 Gas Sensing Materials Roadmap for discussing 29 gas sensing materials and their applications in different gas sensors by different experts.
