The project is dedicated to the synthesis of perovskites doped with transition metal elements and/or noble metals. In particular, the candidate will study the impact of noble metal dopants on the surface via impregnation or doped into the structure of the perovskite. The impact of noble metal doping and their exsolution on the surface will also impact the chemical and structural environment of the transition metal dopants. The impact of both, noble metal and transition metal doping will be studied for CO and methane oxidation in order to differentiate between surface and bulk activity.
