Outline of Final Research Achievements

This work aims to develop S-SWCNT-based novel sensing technology to detect a weak doping organic gases. The core idea is to utilize cascade (multi-step) chemical reactions to convert a weak doping organic gases to a strong doping chemical species.
In particular, we focused on the detection of ethylene, a plant hormone, using highly active catalyst to convert ethylene to acetaldehyde, a chemical reagent to convert the acetaldehyde to acidic gas, and SWCNT-electrode that sensitively detect the acidic gases. Based on the cascade sensor, we are successfully detect ethylen sensitively and selectively. The sensor will be useful for reducing food loss, etc.

Academic Significance and Societal Importance of the Research Achievements

Society5.0の実現のため、室温半導体材料を用いた小型ガスセンサが注目されているが、高感度かつ高選択的に検出できるガスの種類は限られている。本研究では、温和な化学反応や、固相触媒、フロー反応を適切に組み合わせることで室温半導体材料(S-SWCNT)を用いて、低活性なガスであるエチレンを高感度かつ高選択的に検出できることを示した。この基礎原理を応用することにより、様々なガスを高度に検出できる小型センサが開発できると期待される。また、植物熟成ホルモンであるエチレンの常時モニタリングを可能にすることでSDGs目標のひとつであるフードロス削減にもつながると期待される。
