General description of activities

Ib Chorkendorff was in 1987 employed at the Department of Physics, DTU, for establishing an experimental activity with in the field of Surface Physics investigating fundamental aspects of surface reactions, especially with emphasis on establishing a fundamental understanding of the technologically important field of catalysis.  Here fundamental aspects of important catalytic processes like Steam Reforming, Methanol Synthesis, and Ammonia Synthesis have been in focus both with respect to understanding existing systems, but also to design new and improved catalytic systems. In recent years have the activities also been broadened to include various aspects of energy technologies related to hydrogen production including photocatalysis, hydrogen storage, and hydrogen conversions in fuel cells. The common denominator of this research has been performed in the framework of Center for Individual Nanoparticle Functionality CINF which offers a unique framework whereby strong initiatives been taken to capitalize on the fundamental insight for finding new and smart materials that may improve our energy production and ensure a better environmental protection. Recently we have engaged in a new collaboration on DTU Catalysis Initiative for Sustainable Energy (CASE) focusing on producing solar fuels utilizing electro- and photocatalysis.

The group applies a broad variety of the most modern surface sensitive methods (STM, HREELS, TPD, LEED, AES, XPS, High-pressure cells in conjunction with UHV and GC's, and Supersonic Molecular Beams, and Cluster Sources for in situ synthesis of new and mass selected nanoparticle materials) just as equipment for testing and measuring activities of real catalysts has been constructed including UHV/high-pressure parallel screening facilities and in situ IR measurements. Equipment for testing of new fuel cell electrode materials has been established including complete fuel cell assemblies for PEM fuel cells with potentiostats and mass spectroscopy. Similar equipment is available for testing and characterization of photocatalysts. Extensive laboratory facilities are also available for material synthesis in connection with catalysis and photo catalysis in general. The group offers an international environment (all group meetings and courses are in English as is all written material) and seven distinguished professors have spent extended periods in the group. Furthermore, there have continuously been students and post-docs from England, Sweden, Germany, USA, Finland, Norway, Italy, Spain, Peru, India, Belarus, China, Korea, and Japan plus an unaccounted number of short-term visitors. The following activities have furthermore been undertaken during this period:

 

·         Establishment of courses in Experimental Surface Physics and Reaction Kinetics and Catalysis including writing a book for the latter course. Also a PhD courses were developed.

·         Supervisor for M.Sc. students (total 33), Ph.D. students (total 49), and post-doc (36) of which many were in collaboration with industries (Haldor Topsøe A/S, NKT Research, IRD Fuel Cells A/S)  and other laboratories (RISØ)

·         Official opponent at M.Sc. and Ph.D. defences at the Physics Institutes at Århus, Odense, Linköping, Uppsala, Eindhoven, Gothenburg, Tampere, Lyon, and Cambridge Universities
