The focus of this project is the development of thermally stable and efficient probe nanoparticles for Luminescence Thermometry and Shell-Isolated Nanoparticle Enhanced Raman Spectroscopy (SHINERS), ultimately leading to a widely applicable analytical tool set for operando spectroscopy in catalytic reactions. Using these techniques, we aim to study the oxidative coupling of methane and the dehydrogenation of propane in order to gain detailed insight in the mechanisms involved, thereby obtaining detailed understanding of the relations between structure, activity, selectivity and local temperature.
