      abstract     = {Hydrogen storage in the form of small molecules and
                      subsequent release are foreseen to play a fundamental role
                      in future energy systems or carbon cycles. Methanol is an
                      ideal hydrogen carrier due to the high H/C ratio, the lack
                      of C–C bonds, and being liquid under ambient conditions.
                      Methanol steam reforming is an advantageous reaction for the
                      release of the chemically bound hydrogen. Pd- or Pt-based
                      intermetallic compounds have shown to be CO2-selective and
                      long-term stable catalytic materials. However, an intrinsic
                      understanding of the underlying processes is still lacking.
                      In this study, we show that the redox activity in the
                      In–Pt system can be steered by gas-phase changes and leads
                      to highly active catalytic materials at 300 °C [1500 mol
                      (H2)/(mol (Pt) × h)] with an excellent CO2 selectivity of
                      $99.5\%,$ thus clearly outperforming previous materials.
                      Reactive transformations between In2Pt, In3Pt2, and In2O3
                      have been identified to cause the high selectivity. Redox
                      activity of intermetallic compounds as part of the catalytic
                      cycle was previously unknown and adds an understanding to
                      the concept of different adsorption sites.},
