Abstract

We present a novel, scaled-up sol–gel synthesis which enables one to produce 20 g batches of highly active and stable carbon supported PtCu₃ nanoparticles as cathode materials for low temperature fuel cell application. We confirm the presence of an ordered intermetallic phase underneath a multilayered Pt-skin together with firm embedment of nanoparticles in the carbon matrix.
