At slow scan rates this leads to increased steady activity for oxygen reduction reaction (ORR). Furthermore, ionic liquids (IL) influence the activity of Pt-based catalysts and can alter the leaching of Pt-alloy catalysts. This study investigates the influence of ILs on the preconditioning of PtNiMo/C catalysts. Therefore, preconditioning parameters as well as the IL employed were varied. ILs with long side chains like [C8fC1][BETI] resulted in a spreading of the activity development during preconditioning over a longer cycle time and with damped amplitude for the activity changes. For shorter side chains like [BMIM][BETI] the development is like the pristine catalyst. Ex-situ and in-situ characterization revealed that [BMIM][BETI] leached fast to the electrolyte, which was not observed for the other ILs. Nevertheless, for all ILs a strongly reduced platinum leaching was observed. Even for the leached [BMIM][BETI] a stable wetting layer influencing the leaching seems to remain. Nevertheless, only for the other ILs where an immobilized bulk phase is remaining a difference in catalyst restructuring during the preconditioning is observed and a higher number of small sized Pt clusters and a lower amount of bigger Pt clusters resulted.</p></p> <h3>Authors with CRIS profile</h3> <div class="entity-map"> <a class="entity" href="/persons/259709598/"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 448 512"><path d="M224 256c70.7 0 128-57.3 128-128S294.7 0 224 0S96 57.3 96 128s57.3 128 128 128zm-45.7 48C79.8 304 0 383.8 0 482.3C0 498.7 13.3 512 29.7 512H418.3c16.4 0 29.7-13.3 29.7-29.7C448 383.8 368.2 304 269.7 304H178.3z"/></svg> <span>Juntao Yang</span> </a> <a class="entity" href="/organisations/210811678/"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 576 512"><!--!
