      Anodic and Cathodic Platinum Dissolution Processes Involve Different Oxide Species 

      Fuchs, Timo; Briega Martos, Valentín; Drnec, Jakub; Stubb, Natalie; Martens, Isaac; Calle Vallejo, Federico; Harrington, David A.; Cherevko, Serhiy; Magnussen, Olaf M. (Wiley, 2023-08)
      The degradation of Pt-containing oxygen reduction catalysts for fuel cell applications is strongly linked to the electrochemical surface oxidation and reduction of Pt. Here, we study the surface restructuring and Pt ...

      Structure dependency of the atomic-scale mechanisms of platinum electro-oxidation and dissolution 

      Fuchs, Timo; Drnec, Jakub; Calle Vallejo, Federico; Stubb, Natalie; Sandbeck, Daniel J. S.; Ruge, Martin; Cherevko, Serhiy; Harrington, David A.; Magnussen, Olaf M. (Springer Nature, 2020-08-24)
      Platinum dissolution and restructuring due to surface oxidation are primary degradation mechanisms that limit the lifetime of Pt-based electrocatalysts for electrochemical energy conversion. Here, we studied well-defined ...
