The Pt\n                    <jats:sub>2<\/jats:sub>\n                    RhFe\/C achieves a superior mass activity of 6.43 A mg\n                    <jats:sub>Pt<\/jats:sub>\n                    <jats:sup>\u22121<\/jats:sup>\n                    , which is 2.23\u2010fold and 3.53\u2010fold higher than those of PtRu\/C and Pt\/C.

This work provides new insights into the role of OH binding strength in the removal of CO species, which is beneficial for the rational design of highly efficient catalysts.\n
