Deeply excavated: Platinum nanoframes with highly concave {740} facets are synthesized directly by a facile oleylamine-assisted solvothermal method. Because of the unique structure and exposed high-index facets, the as-prepared Pt nanoframes exhibit very high electrocatalytic activity and remarkable stability for the oxygen reduction reaction and the oxidation of methanol and formic acid.
