      abstract     = {The observable reaction rate of heterogeneously catalyzed
                      reactions is known to be limited either by the intrinsic
                      kinetics of the catalytic transformation or by the rate of
                      pore and/or film diffusion. Here, we show that in gas
                      generation reactions from liquid reactants, the nucleation
                      of gas bubbles in the catalyst pore structure represents an
                      additional important rate-limiting step. This is highlighted
                      for the example of catalytic hydrogen release from the
                      liquid organic hydrogen carrier compound
                      perhydro-dibenzyltoluene. A nucleation-inhibited catalytic
                      system produces only dissolved hydrogen with fast saturation
                      of the fluid phase around the active site, while bubble
                      formation enhances mass transfer by more than a factor of 50
                      in an oscillating reaction regime. Nucleation can be
                      efficiently triggered not only by temperature changes and
                      catalyst surface modification but also by a mechanical
                      stimulus. Our work sheds new light on performance-limiting
                      factors in reactions that are of highest relevance for the
                      future green hydrogen economy.},
