Chemical reactions at surface form the basis for heterogeneous catalysis. A detailed understanding of the microscopic steps governing surface reactions is a long-standing goal in chemical physics. Despite this, the direct observation of short-lived intermediates and transition states remains a challenge due to the technical difficulties involved in probing such species. We have developed methods for real-time probing of catalytic surface reactions and with the rapid development of both optical and x-ray lasers have access to new powerful ultrafast spectroscopies that allow us to start probing electronic structure of short-lived intermediates and species around the transition state of catalytic surface reactions. The present proposal aims at building a long-term experimental research program for the study of dynamics in surface reactions. The experiments will be based on optical laser experiments and free-electron laser studies. Model systems will be constructed with relevance to industrially important processes, such as Fischer-Tropsch synthesis, ammonia synthesis and three-way catalysts. The proposed studies will provide a great step forward in the fundamental understanding of heterogeneous catalysis and in a longer time-frame the results can lead to more efficient prediction of efficient new catalysts.
