We have a strong background in chemistry, catalysis, spectroscopy and analytics, which we use to elucidate reaction networks and mechanisms with the aim to develop novel catalysts. With this competence we have broadened in recent years our activities from exhaust gas catalysis towards catalyst development for energy conversion processes in general to support the research activities of the Laboratory for Sustainable Energy Carriers and Processes (LEP), of the PSI Center for Energy and Environmental Sciences (CEE) and of other groups within and outside PSI. Some of our core activities are described in the flyer of CEE.
