Abstract
Monodisperse bimetallic alloyed palladium–copper nanocrystals are uniformly supported on reduced graphene oxide nanosheets by a one-pot solvothermal strategy, with an average size of 6.81 nm. As a result, the as-prepared nanocomposites have the enlarged electrochemically active surface area (49.2 m2 g−1), and display the improved electrocatalytic performance and high methanol-tolerance ability for oxygen reduction reaction in alkaline media, compared with commercial Pd black and RGOs. Those RGOs-supporting Pd–Cu alloys would have potential applications in fuel cells.
