“Background Alloyed AuPd bimetallic nanoparticles have drawn great attention because of their unique properties for optical, electronic, magnetic, and catalytic applications [1–3]. Especially, AuPd alloyed nanoparticles have been widely investigated as catalysts for benzyl oxidation, direct synthesis of hydrogen peroxide from H2 and O2, and CO oxidation [1, 3]. Currently, a variety of approaches have been reported on the preparation of alloyed AuPd nanoparticles, including chemical reduction [3–5], electrochemical reduction [1, 6], thermolysis of double metallic salts [2], and sonochemical reduction [7]. Among all these methods, the chemical reduction is mostly applied. It is normally performed using a reducing agent, like NaBH4 or H2, in the presence of stabilizer or protective molecule for the size and structure control.
