Talk - Scanning tunneling microscopy studies of metal-oxide and sulfide catalysts

Talk by Jeppe Vang Lauritsen

Aarhus University


The development of new, non-expensive materials for catalysis is seen as a crucial progress for securing energy resources and for better protection of the environment. Obtaining detailed control of materials on the nanoscale is of essence in catalysis, but often a lack of insight into the fundamental physical and chemical processes occurring on catalytically active surfaces hampers the progress. We pursue the goal of understanding catalytic processes on surfaces by focusing on what happens on the atomic-level. Scanning Probe Microscopy techniques (SPMs) are particularly strong techniques in this regard, since they allow us to visualize the atomic structure of surfaces and sometimes directly see the outcome of catalytic reactions. In my talk, I give examples on how we successfully use the SPM in interplay with other surface science techniques to investigate industrially used catalysts for e.g. NOx pollution abatement, new earth-abundant catalyst materials for H2 production and metalsulfides for use in hydrotreating catalysis
