| Outline of Research at the Start |
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.
|
| Outline of Annual Research Achievements |
Firstly, a mesoporous-macroporous silver-based substrate has been developed using the soft-template method, which yields a plasmon-active 3D substrate with a strong electromagnetic field that outperforms classic plasmonic substrates. The metal surface was functionalized with 4-decylphenylbenzene diazonium tosylate to covalently protect the silver surface and introduce additional hydrophobic properties. Secondly, a vapor-assisted method was developed for the surface-assisted growth of the metal-organic framework (MOF) UiO-66 Iodine on mesoporous gold films. This developed sensor was then used to probe chlorine-containing contaminants in various water sources, including those containing proteins or starch, wastewater, and marine water.

| Current Status of Research Progress |
Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
We have achieved the design of a new SERS sensor, and it is progressing according to plan.
|
| Strategy for Future Research Activity |
The plasmon-active porous materials that have been created will undergo testing to detect environmental pollutants via SERS in complex matrices that contain a variety of molecules and interfering substances. Furthermore, the mesoporous plasmon-active substrates will be evaluated for their ability to drive light-induced reactions to degrade environmental pollutants. The experimental parameters for plasmon catalysis will be fine-tuned to achieve the highest reaction rate, conversion, and reaction selectivity.
