Big and small : Chemically modifying platinum with calix[4]arene yields a highly stable anode catalyst that effectively suppresses the oxidation reduction reaction without altering the maximum activity for the hydrogen oxidation reaction (see picture, Pt blue, C gray, O red, S yellow). This behavior extends from long‐range‐ordered stepped single‐crystal surfaces to nanocatalysts.
