Gas sensor technology is widely utilized in various areas ranging from home security, environment and air pollution, to industrial production. It also hold great promise in non-invasive exhaled breath detection and an essential device in future internet of things. The past decade has witnessed giant advance in both fundamental research and industrial development of gas sensors, yet current efforts are being explored to achieve better selectivity, higher sensitivity and lower power consumption. The sensing layer in gas sensors have attracted dominant attention in the past research. In addition to the conventional metal oxide semiconductors, emerging nanocomposites and graphene-like two-dimensional materials also have drawn considerable research interest. This inspires us to organize this comprehensive 2020 gas sensing materials roadmap to discuss the current status, state-of-the-art progress, and present and future challenges in various materials that is potentially useful for gas sensors.
气体传感器技术广泛应用于家庭安全、环境和空气污染、工业生产等各个领域。它在非侵入性呼气检测方面也具有很大的应用前景，是未来物联网的重要组成部分。过去十年，气体传感器在基础研究和工业发展方面都取得了巨大的进步，但目前仍在努力实现更好的选择性、更高的灵敏度和更低的功耗。在过去的研究中，气体传感器的传感层引起了人们的极大关注。除了传统的金属氧化物半导体外，新兴的纳米复合材料和类石墨烯二维材料也引起了相当大的研究兴趣。这启发我们组织了这个全面的 2020 年气体传感材料路线图，以讨论各种可能对气体传感器有用的材料的现状、最新进展、当前和未来的挑战。
