                      doped tin oxide (ATO) supported platinum nanoparticles are
                      considered a more stable replacement for conventional carbon
                      supported platinum materials for the oxygen reduction
                      reaction. However, the interplay of antimony, tin and
                      platinum and its impact on the catalytic activity and
                      durability has only received minor attention. This is partly
                      due to difficulties in the preparation of morphology- and
                      surface-area-controlled antimony-doped tin oxide materials.
                      The presented study sheds light onto catalyst–support
                      interaction on a fundamental level, specifically between
                      platinum as a catalyst and ATO as a support material. By
                      using a previously described hard-templating method, a
                      series of morphology controlled ATO support materials for
                      platinum nanoparticles with different antimony doping
                      concentrations were prepared. Compositional and
                      morphological changes before and during accelerated stress
                      tests are monitored, and underlying principles of
                      deactivation, dissolution and catalytic performance are
                      elaborated. We demonstrate that mobilized antimony species
                      and strong metal support interactions lead to Pt/Sb alloy
                      formation as well as partially blocking of active sites.
                      This has adverse consequences on the accessible platinum
                      surface area, and affects negatively the catalytic
                      performance of platinum. Operando time-resolved dissolution
                      experiments uncover the potential boundary conditions at
                      which antimony dissolution can be effectively suppressed and
                      how platinum influences the dissolution behavior of the
                      support.},
