Reactivity at gas-solid interfaces plays a fundamental role in a large number of natural processes: heterogenous catalysis, atmospheric reactions, interstellar matter, biological or geological media. Recently, reactivity studies have greatly benefited from the development of individual atom, molecule or radical manipulation and reaction control on surfaces. The latter technique allows to pilot step by step chemical reactions, to observe elementary reactions in real time, to construct nanostructured catalysts, etc... Molecular beams allow to simulate elementary steps in catalytic processes like the formation and stabilization of reactive radicals or direct reactions between adsorbates and atoms/molecules of the gas phase. On the other hand, theoretical methods for the determination of the electronic structure of adsorbates on surfaces have reached the point where they are able to deal with complex situations, like the determination of reactive paths, even when the latter involve defects or local modifications of the surface. The concerted theoretical and experimental approach has proved to be very successful for the elucidation of elementary microscopic reaction steps of molecules at surfaces. In this workshop, the current state of the art in both theory and experiment will be reviewed and promising new developments discussed.
