アミン吸収型CCUSで問題となるMEA放出をリアルタイム検知するため、金属酸化物半導体（MOS）ガスセンサーの研究動向を整理したレビュー。貴金属修飾やヘテロ接合構築によりAOx系センサーの性能が向上し、室温検出も可能になりつつある。SnO2系が感度・選択性・応答速度・安定性で優位な一方、ABO3ペロブスカイト系は湿度耐性と安定性に課題が残る。低温動作・耐湿性・長期耐久性の改善が実用化の鍵と指摘する。

English

This mini review surveys metal oxide semiconductor (MOS) gas sensors for detecting monoethanolamine (MEA) emissions in amine-based carbon capture. Noble-metal decoration and heterojunction engineering markedly improve AOx-based sensor performance, with some enabling room-temperature MEA detection. SnO2-based sensors show the best sensitivity, selectivity, response speed and stability, while ABO3 perovskite sensors remain limited by poor humidity resistance and durability. Low-temperature operation, humidity tolerance and long-term reliability are flagged as priorities for industrial translation.

日本のGX文脈において

CCUSは日本のGX実現に向けた重要技術であり、アミン放出のモニタリング技術は環境影響評価や地域合意形成、ひいてはCCUS事業のESG説明責任に直結する。国内CCUS実装を進める事業者にとって、計測・モニタリング技術の成熟度を把握する材料となる。

In the global GX context

As CCUS scales under net-zero pathways, amine emission monitoring becomes part of environmental performance and disclosure assurance for capture operators. This review maps sensor readiness, informing the measurement, reporting and verification (MRV) layer that underpins credible CCUS claims in global climate disclosure.

📄 Abstract（原文）

Carbon capture, utilization and storage (CCUS) is indispensable for achieving global carbon neutrality, and amine-based chemical absorption remains the most mature and widely deployed technology. However, amine emissions during operation result in absorbent loss, secondary pollution and potential public health risks, while conventional offline detection methods are unable to satisfy the requirements of real-time monitoring. This review systematically summarizes recent progress in metal oxide semiconductor (MOS) gas sensors for monoethanolamine (MEA) detection, with particular emphasis on AOx-based systems. The effects of the base material, microstructure and modification strategies, including noble metal decoration and heterojunction construction, on sensing performance are critically compared. Through such modifications, AOx-based sensors have achieved markedly improved sensing performance, and several are capable of detecting MEA at room temperature. The feasibility of existing sensing materials is further evaluated in the context of post-combustion amine capture. Among the reported systems, SnO2-based sensors exhibit clear advantages for MEA detection, including high sensitivity, favorable selectivity, rapid response and recovery, and satisfactory stability and repeatability. In contrast, studies on ABO3 perovskite-based sensors remain limited; although these materials show fast response, they continue to suffer from poor stability and insufficient humidity resistance. Future research should therefore focus on low-temperature operation, enhanced humidity tolerance and long-term durability, so as to accelerate the industrial translation of MOS gas sensors and support the sustainable development of CCUS.
