FePt concave nanocubes with enhanced methanol oxidation activity

FePt concave nanocubes enclosed by highly active high-index atom steps were synthesized by a facile process. The oleic acid was demonstrated to be the key point for the formation of FePt concave nanocubes. Due to the concave structure, the FePt concave nanocubes exhibit higher electrocatalytic activity than either FePt nanocubes or commercial Pt catalysts in methanol oxidation.
