Interplay between metal‒support interaction and stability in Pt/Co3O4(111) model catalysts


Y. Lykhach et al., J. Mater. Chem. A. 6, 23078 (2018); DOI: 10.1039/C8TA08142E



The interplay between metal‒support interaction and thermal stability of Pt nanoparticles supported on well-ordered Co3O4(111)/Ir(100) films have been investigated by means of synchrotron radiation photoelectron spectroscopy. We found that the electronic metal‒support interaction gives rise to the formation of partially oxidized Ptδ+ species at the Pt/Co3O4(111) interface. The stability of the supported Pt particles is coupled to the oxidation state of Ptδ+ species, which can be reduced or oxidized depending on the Pt coverage and reactive environment.
