| 研究開始時の研究の概要 |
The developed plasmon-active porous materials will be tested for SERS detection of environmental pollutants in the complex matrix containing different molecules and interfering matter. The mesoporous plasmon-active substrates will be tested in the light-driven reactions of environmental pollutants degradations. The experimental conditions for plasmon catalysis will be optimized to get the highest reaction rate, conversion and selectivity of reactions.

| 研究実績の概要 |
The objective of this project is to design novel functional porous materials by integrating mesoporous plasmonic films with chemically grafted organic layers to enhance selectivity. These materials will be applied to (i) monitoring food and water safety through optical sensing and (ii) utilizing greenhouse and related gases for organic synthesis.
New plasmon-active nanoporous materials were successfully prepared and their performance was investigated in terms of Surface-Enhanced Raman Scattering (SERS) detection of environmental pollutants in complex matrices containing various molecules and interfering substances. Particularly, hierarchical macro- and mesoporous Ag materials with organic layer coating achieved practical detections of microplastics, and the results were accepted for publication in Nature Communications (still not published). Additionally, the mesoporous plasmon-active substrates were evaluated in light-driven reactions for the degradation of environmental pollutants.
