In my research, I am working on the decenrtalized production of ammonia as a local energy storage from renewable energies. The fokus is on Haber-Bosch catalysts of the second generation. The aim is to develop a flow reactor as well as the associated process on the laboratory scale and its transfer to the industrial scale.
