A simple method for preparing Ag/Pd nanorings is reported. Energy dispersive X-ray element mapping results showed a random distribution of Ag and Pd atoms over the nanoring, indicating that the nanorings were made of an alloy of Ag and Pd. These nanorings were then successfully used as catalysts in electroless copper deposition. Results of quartz crystal microbalance measurements revealed that the catalytic activity of prepared Ag/Pd nanorings was better than that of monometallic Ag and Pd nanoparticles.
