Development of surface-enhanced Raman spectroscopy techniques for the study of surface reactions over heterogeneous catalysts
Supervisor: Prof. dr. ir. Bert M. Weckhuysen
In this work, plasmonic nanostructures are implemented to make Raman spectroscopy into a surface-sensitive technique for the study of adsorbates on a catalyst surface. In particular, Au and Ag nanoparticles are isolated with SiO2 and TiO2 coatings to obtain thermally Raman signal enhancers. This technique is referred to as shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS). Solid metals are assembled over the shell-isolated nanoparticles by wet-impregnation and spark-ablation for the study of hydrogenation catalysis.
