Nitrous oxide (NO), also known as laughing gas, is arguably one of the most detrimental greenhouse gases while concurrently being overlooked by the public. Specifically, NO is ∼300 times more damaging than its better-known counterpart carbon dioxide (CO) and has a longer-lived lifetime in the atmosphere than CO. There exist both natural and anthropogenic sources of NO, and thus, for a better understanding of sources, capture, and decomposition, it is pivotal to identify NO within the nitrogen biosphere. This review covers the past and current low-cost NO gas-sensing technologies, focusing specifically on low-cost metal oxide semiconductors (MOSs), chemiresistive and electrochemical sensors that can provide spatial and temporal monitoring of NO emissions from various sources. Additionally, compositional modifications to MOsS using metal-organic frameworks (MOFs) are discussed, potentially facilitating new awareness and efforts for increased sensing performance and functionality in NO detection.
一氧化二氮（NO），也被称为笑气，可谓是最具危害性的温室气体之一，然而却同时被公众所忽视。具体而言，NO的危害程度约是其更为人熟知的二氧化碳（CO）的300倍，并且在大气中的存留时间比CO更长。NO既有自然来源也有人为来源，因此，为了更好地理解其来源、捕获和分解，在氮生物圈中识别NO至关重要。本综述涵盖了过去和当前的低成本NO气体传感技术，特别关注能够对来自各种来源的NO排放进行空间和时间监测的低成本金属氧化物半导体（MOS）、化学电阻式和电化学传感器。此外，还讨论了使用金属有机框架（MOF）对MOS进行成分改性，这可能有助于提高人们对在NO检测中提高传感性能和功能的新认识并推动相关努力。
