摘要
We report a novel microwave-induced fast and efficient synthesis of sub-10 nm sized palladium-decorated FeCo@Fe core-shell nano-particles (ca. 3-7 nm) from a large-sized FeCo@Fe (0.21-1.5 mu m) precursor, suggesting 'top-down' nanosizing. The high electrochemical surface area, tolerance to methanol during oxygen reduction reaction, and the excellent stability of FeCo@Fe@Pd in alkaline electrolytes indicate that this nanomaterial may find future applications in Pd-based catalysis and/or alkaline fuel cells.
