                      thorough understanding of (electro)catalytic surface
                      transformations under dynamic reaction conditions is of
                      utmost importance for a knowledge-based catalyst design.
                      Friction Force Microscopy (FFM) as an atomic force
                      microscopy based technique is capable to obtain materials
                      specific information in addition to electrical and
                      structural properties of catalysts in liquid media and under
                      electrochemical conditions. This is especially relevant as
                      surface transitions at early catalytic activity are subtle
                      and might be easily overseen by pure topography mapping.It
                      is the objective of this work to demonstrate the
                      capabilities of FFM for investigating (electro)catalysts. It
                      has been shown earlier that the frictional behavior of a
                      bare metal differs significantly from its
                      oxy/hydroxy-terminated surface under electrochemical
                      conditions.The new results on combined electrochemical and
                      frictional experiments on well-defined epitaxial perovskite
                      oxide structures in aqueous liquids are illustrated. This
                      approach represents the first application of these technique
                      with respect to (electro)catalysis. Simultaneously recorded
                      cyclic voltammograms and lateral forces, so-called
                      frictograms, allow to correlate subtle and local surface
                      transformations and the applied potential precisely.In
                      conclusion, FFM represents a versatile new operando
                      technique to investigate (electro)catalytic reactions under
                      dynamic conditions on a local scale with high sensitivity to
                      materials and structural changes.},
