Motivation

The distributed production of green ammonia through plasma catalysis is a promising pathway to achieve energy transition and decarbonization. A key factor in advancing this technology is understanding the complex gas-plasma-surface interactions, which result in synergy effects that can enhance the synthesis efficiency. Gaining insight into these interactions is essential to optimize catalyst performance and reactor conditions.

In-situ diagnostics play a crucial role in unraveling these processes by providing direct evidence of surface composition and enabling the identification of potential reaction pathways. However, the development of non-intrusive optical diagnostic techniques for plasma-catalyst surfaces remains a significant challenge. These diagnostics must be carefully designed and tested to ensure they capture real-time data without disturbing the delicate plasma-catalyst environment.

This project focuses on designing an optical test rig equipped with a user-friendly spectrometer to measure surface-enhanced Raman scattering (SERS) on plasma catalyst surfaces. Please feel free to reach out for more details!
