“…Several approaches to the synthesis various bimetallic NPs have been reported, including the chemical reduction method, electrochemical deposition, ethylene glycol-assisted polyol process, photochemical or radiolytic routes, and the galvanic replacement reaction (GRR) [4][5][6][7]. Among them, the GRR method can be used to prepare a wide variety of bimetallic nanostructures such as spherical nanoshells, cubic nanoboxes, nanocages, nanotubes, and nanodendrites [7][8][9][10].…”
